  • Accessible search and the role of metadata
    • Pages: 2 - 17
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 2-17, March 2018.
      Purpose Some of the usability and accessibility problems of search interfaces emanate from poorly organized search results, where different types of metadata are employed. Metadata is important to make well-informed selection of resources. However, putting too much of it on search interfaces could be counterproductive. Therefore, studies suggest that metadata-related decisions need to be informed by user requirements. The purpose of this paper is to explore library metadata from usability and accessibility perspectives. It identifies search-related problems users with print disability face and explores how metadata-related decisions could be tailored to improve their experience in resource discovery and access. Design/methodology/approach A questionnaire was posted online for two months. It targeted people with print disability who are using the audiobook app Lydhør. It was finally possible to gather responses from 113 respondents. Two open-ended questions dealing with search and metadata issues were selected for qualitative analysis. Findings Most respondents mentioned the Lydhør’s intolerance to spelling errors as a problem. Some suggested the use of faceted metadata, such as genres, for exploratory search to offset frustration caused by spelling errors. Most respondents indicated the importance of summaries to be shown among search results, implying their significance for lookup searches. There have been few demands related to accessibility metadata. Originality/value This study could be a valuable input for inclusive/universal design of library search interfaces.

  • The design of early childhood makerspaces to support positive
           technological development
    • Pages: 75 - 96
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 75-96, March 2018.
      Purpose With the advent of the maker movement, there has been a new push to explore how spaces of learning ought to be designed. The purpose of this paper is to integrate three approaches for thinking about the role of design of the learning environment: the makerspace movement, Reggio Emilia’s Third Teacher approach, and the positive technological development (PTD) framework. Design/methodology/approach This paper describes two case studies that involved the design of two different early childhood makerspaces (ECMSs) through a co-participatory design experience: the Kindergarten Creator Space at the International School of Billund in Denmark; and the ECMS at (removed for blind review), a resource library in Medford, MA. Findings Based on the foundational education framework of PTD, and ideas from the field of interior design, this paper describes the design principles of several successful makerspaces, and case examples of children who use them. Originality/value By grounding the theoretical discussion in three approaches, the authors aim to suggest design elements of physical spaces in schools and libraries that can promote young children’s learning through making. Recommendations are discussed for practitioners and researchers interested in ECMSs.

  • Factors influencing people’s health knowledge adoption in social
    • Pages: 129 - 151
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 129-151, March 2018.
      Purpose The purpose of this paper is to explore the factors influencing people’s health knowledge adoption in social media, with an eye toward promoting health information literacy and healthy behavior. Design/methodology/approach Based on the integration of sense-making theory, social influence theory, information richness theory, fear appeal theory, and ELM (elaboration likelihood method), a health knowledge adoption model is constructed. Taking spondylopathy as an example, high health threat and low health threat experiments and questionnaires are designed to complete the empirical study. In all, 355 effective survey samples are collected and analyzed, leveraging a partial least squares method. Findings Research results indicate that perceived knowledge quality, perceived knowledge consensus, and perceived source credibility have positive effects on health knowledge adoption via the mediator – trust; knowledge richness contributes to the perception of knowledge quality, source credibility, and knowledge consensus, especially under high health threat; health threat has significant positive moderating effects on the relationship between trust and health knowledge adoption, and the relationship between perceived knowledge quality and trust, with negative moderating effects on the relationships between perceived knowledge consensus, perceived source credibility, and trust. Originality/value This paper examines the mediating effecting of trust in the process of health knowledge adoption. Based on the integration of fear appeal theory, social influence theory, sense-making theory, information richness theory and elaboration likelihood model, this study investigates the factors influencing health knowledge adoption in social media from the perspective of a user, and explores the moderating effect of health threat on health knowledge adoption.

  • Establishing evaluation criteria for e-dictionaries
    • Pages: 152 - 166
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 152-166, March 2018.
      Purpose The purpose of this paper is to identify criteria according to which e-dictionaries can be evaluated. Information technology can be used to enhance e-dictionaries, but if not done carefully, information tools that completely overwhelm a user with irrelevant information can be developed. Criteria are necessary according to which e-dictionaries can be developed and evaluated to ensure tools that only provide relevant information on demand. Design/methodology/approach A literature review was conducted to identify trends in lexicography and modern information technology. Previous usability studies were considered to identify key usability issues. The information was synthesised to identify a set of criteria. Findings It was found the e-dictionaries should be evaluated according to their content, information architecture, navigation, access (searching and browsing), help, customisation and use of other innovative technologies. Originality/value A comprehensive set of criteria has been identified that can be used to evaluate e-dictionaries and to guide lexicographers in the development of e-dictionaries.

  • Motivating issues affecting students’ use of social media sites in
           Ghanaian tertiary institutions
    • Pages: 167 - 179
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 167-179, March 2018.
      Purpose Social media usage has become popular among the youth. The popularity and acceptance of this tool by the youth in large numbers make it necessary to find out more about the reasons why the youth are so interested in social media sites and as a result rely so much on it in every social engagement irrespective of the dangers or demerits it poses. The paper aims to discuss these issues. Design/methodology/approach With the adoption of survey methodology, this paper randomly selected 204 students majoring in sociology from University of Ghana and Kwame Nkrumah University of Science and Technology to participate in the study. Findings Using the uses and gratifications theory, this study identified the following: WhatsApp was found to be the most widely used social media tool in both institutions; chatting and keeping in touch with loved ones and maintaining distant relationships are the major factors that motivate students in both institutions to use social media sites. The results further indicated that students are highly influenced by social media sites and, therefore, this has become their main medium of communication within and outside campus. Practical implications Social media, one way or the other is controlling the world and everything in it. The exposure of students to this tool requires the taking of certain relevant measures to direct the focus of its usage in tertiary institutions. It is against this background that this paper strongly recommended its integration into the academic system and the enshrinement of social media policies in the handbook of university students in Ghana. Originality/value This paper adds to existing literature on students frequent use of social media and confirms the assumptions of the uses and gratifications theory which simply asks the question why and how people use media.

  • Overcoming disintermediation: a call for librarians to learn to use web
           service APIs
    • Pages: 180 - 190
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 180-190, March 2018.
      Purpose The purpose of this paper is to argue that academic librarians must learn to use web service APIs and to introduce APIs to a non-technical audience. Design/methodology/approach This paper is a viewpoint that argues for the importance of APIs by identifying the shifting paradigms of libraries in the digital age. Showing that the primary function of librarians will be to share and curate digital content, the paper shows that APIs empower a librarian to do that. Findings The implementation of web service APIs is within the reach of librarians who are not trained as software developers. Online documentation and free courses offer sufficient training for librarians to learn these new ways of sharing and curating digital content. Research limitations/implications The argument of this paper depends upon an assumption of a shift in the paradigm of libraries away from collections of materials to access points of information. The need for libraries to learn APIs depends upon a new role for librarians that anecdotal evidence supports is rising. Practical implications By learning a few technical skills, librarians can help patrons find relevant information within a world of proliferating information sources. Originality/value The literature on APIs is highly technical and overwhelming for those without training in software development. This paper translates technical language for those who have not programmed before.

  • Corpus linguistics is not just for linguists
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to generate awareness of and interest in the techniques used in computer-based corpus linguistics, focusing on their methodological implications for research in library and information science (LIS). Design/methodology/approach This methodology paper provides an overview of computer-based corpus linguistics, describes the main techniques used in this field, assesses its strengths and weaknesses, and presents examples to illustrate the value of corpus linguistics to LIS research. Findings Overall, corpus-based techniques are simple, yet powerful, and they support both quantitative and qualitative analyses. While corpus methods alone may not be sufficient for research in LIS, they can be used to complement and to help triangulate the findings of other methods. Corpus linguistics techniques also have the potential to be exploited more fully in LIS research that involves a higher degree of automation (e.g. recommender systems, knowledge discovery systems, and text mining). Practical implications Numerous LIS researchers have drawn attention to the lack of diversity in research methods used in this field, and suggested that approaches permitting mixed methods research are needed. If LIS researchers learn about the potential of computer-based corpus methods, they can diversify their approaches. Originality/value Over the past quarter century, corpus linguistics has established itself as one of the main methods used in the field of linguistics, but its potential has not yet been realized by researchers in LIS. Corpus linguistics tools are readily available and relatively straightforward to apply. By raising awareness about corpus linguistics, the author hopes to make these techniques available as additional tools in the LIS researcher’s methodological toolbox, thus broadening the range of methods applied in this field.

    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to investigate the availability of embedded metadata within images of digital cultural collections. It is designed to examine a proposed hypothesis that most digitally derived images of cultural resources are stripped of their metadata once they are placed on the web. Design/methodology/approach A sample of 603 images were selected randomly from four cultural portals which aggregate digitized cultural collections, then four steps in the data collection process took place to examine image metadata via the web-based tool and windows application. Findings The study revealed that 28.5 percent of the analyzed images contained metadata, no links exist between image embedded metadata and its metadata record or the pages of the websites analyzed, and there is a significant usage of Extensible Metadata Platform to encode embedded metadata within the images. Practical implications The findings of the study may encourage heritage digital collection providers to reconsider their metadata preservation practices and policies to enrich the content of embedded metadata. In addition, it will raise awareness about the potential and value of embedded metadata in enhancing the findability and exchange of digital collections. Originality/value This study is ground breaking in that it is one of the early studies, especially in the Arab world, which aim to recognize the use of image embedded metadata within cultural heritage digital collections on the web.

  • Characterizing queries in cross-device OPAC search: a large-scale log
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The study focused on online public access catalog (OPAC) users’ cross-device search behavior. The purpose of this paper is to understand the characteristics of cross-device OPAC searches, and to identify query reformulation (QR) patterns during device transitions. Design/methodology/approach The transaction log from a university library, spanning six months, was used to conduct the quantitative analysis. The query vocabulary richness, which refers to the average number of unique words each query contains in a search session, can evaluate query diversity, and contribute to the analysis of QR. Findings The results show that PC-PC transition is the most important pattern of device transition. The time interval of device transition was different to the time interval of transitions in web searches. Short device transitions mainly occurred in daytime, and the number of transitions that occurred in less than one minute was higher than on the web. Searches for Industry and Technology triggered the most device transitions, and the users tended to choose the same search field. In addition, the authors made a detailed analysis of the reasons for same-type device transitions and different-type device transitions. Furthermore, the authors focused on the characteristics of adjacent QR patterns. The authors not only refined the concept of cross-device to include the same-type device transition, but also summarized the characteristics of the cross-device QR patterns, which can be used to predict post-switch queries. Originality/value This study extends research into cross-device interaction and cross-device search to the domain of digital library research. The authors also introduced QR perspective on cross-device interaction on OPAC.

  • Hakka genealogical migration analysis enhancement using big data on
           library services
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to explore the data connection, spatial distribution characteristics and trends in genealogical information. First, it implements a spatial-temporal visualization of the Hakka genealogical information system that makes these individual family pedigree charts appear as one seamless genealogy to family and researchers seeking connections and family history all over the world. Second, this study applies migration analysis by applying big data technologies to Hakka genealogies to investigate the migration patterns of the Hakka ethnic group in Taiwan between 1954 and 2014. This innovative library service enhances the Hakka genealogical migration analysis using big data. Design/methodology/approach The platform is designed for the exchange of genealogical data to be used in big data analysis. This study integrates big data and geographic information systems (GIS) to map the population distribution themes. The general procedure included collecting genealogical big data, geographic encoding, gathering the map information, GIS layer integration and migration map production. Findings The analytical results demonstrate that big data technology is highly appropriate for family migration history analysis, given the increasing volume, velocity and variety of genealogical data. The spatial-temporal visualization of the genealogical research platform can follow family history and migration paths, and dynamically generate roadmaps to simplify the cartographic steps. Practical implications Technology that combines big data and GIS is suitable for performing migration analysis based on genealogy. A web-based application for spatial-temporal genealogical information also demonstrates the contribution of innovative library services. Social implications Big data play a dominant role in library services, and in turn, provide an active library service. These findings indicate that big data technology can provide a suitable tool for improving library services. Originality/value Online genealogy and family trees are linked with large-volume, growing data sets that are complex and have multiple, autonomous sources. The migration analysis using big data has the potential to help genealogy researchers to construct minority ethnic history.

  • Text mining based theme logic structure identification: application in
           library journals
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose Library intelligence institutions, which are a kind of traditional knowledge management organization, are at the frontline of the big data revolution, in which the use of unstructured data has become a modern knowledge management resource. The paper aims to discuss this issue. Design/methodology/approach This research combined theme logic structure (TLS), artificial neural network (ANN), and ensemble empirical mode decomposition (EEMD) to transform unstructured data into a signal-wave to examine the research characteristics. Findings Research characteristics have a vital effect on knowledge management activities and management behavior through concentration and relaxation, and ultimately form a quasi-periodic evolution. Knowledge management should actively control the evolution of the research characteristics because the natural development of six to nine years was found to be difficult to plot. Originality/value Periodic evaluation using TLS-ANN-EEMD gives insights into journal evolution and allows journal managers and contributors to follow the intrinsic mode functions and predict the journal research characteristics tendencies.

  • Heuristic evaluation of e-dictionaries
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to discuss the heuristic evaluations of five e-dictionaries according to the criteria developed by Ball and Bothma (2018). E-dictionaries are increasingly making use of modern information technology to create advanced information tools. It is necessary to ensure that these new products are still usable. Heuristic evaluation is a usability evaluation method used to evaluate the usability of a product. Design/methodology/approach Five e-dictionaries were evaluated through heuristic evaluation. This method requires an evaluator to evaluate a product by using a set of criteria or guidelines. Findings Various usability issues, as well as good features of e-dictionaries, could be identified through these evaluations, and are discussed under the categories of content, information architecture, navigation, access (searching and browsing), help, customisation and use of other innovative technologies. Originality/value Through the evaluations in this study, the criteria could be validated and an example of how the criteria can be used to evaluate e-dictionaries could be presented.

  • Impacts of quality antecedents on faculty members’ acceptance of
           electronic resources
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to assess whether quality antecedents and individual characteristics can influence faculty members’ continued usage intention of electronic resources (e-resources) in selected public universities in Tanzania. Design/methodology/approach A total of 204 faculty members participated in the study from three public universities in Tanzania. The study used structural equation modelling, ANOVA and t-tests to perform analyses. Findings Better educated and middle-aged faculty members with a wide experience of using e-resources are more likely to continue using e-resources. Information quality had positive relationship with continued usage intention of e-resources while service quality had indirect impact to continued usage intention through information quality and system quality. Originality/value Based on the DeLone and McLean information systems success model, this study integrates quality factors (information, service and system quality) and individual characteristics as antecedents to the continued usage intention of e-resources. The study comprehensively documents empirical findings on impacts of quality factors and individual characteristics on e-resources in a developing country. The study reveals results that are useful for enhancing usage of e-resources by faculty in other institutions with similar conditions.

  • Discovering research topics from library electronic references using
           latent Dirichlet allocation
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose Discovering the research topics and trends from a large quantity of library electronic references is essential for scientific research. Current research of this kind mainly depends on human justification. The purpose of this paper is to demonstrate how to identify research topics and evolution in trends from library electronic references efficiently and effectively by employing automatic text analysis algorithms. Design/methodology/approach The authors used the latent Dirichlet allocation (LDA), a probabilistic generative topic model to extract the latent topic from the large quantity of research abstracts. Then, the authors conducted a regression analysis on the document-topic distributions generated by LDA to identify hot and cold topics. Findings First, this paper discovers 32 significant research topics from the abstracts of 3,737 articles published in the six top accounting journals during the period of 1992-2014. Second, based on the document-topic distributions generated by LDA, the authors identified seven hot topics and six cold topics from the 32 topics. Originality/value The topics discovered by LDA are highly consistent with the topics identified by human experts, indicating the validity and effectiveness of the methodology. Therefore, this paper provides novel knowledge to the accounting literature and demonstrates a methodology and process for topic discovery with lower cost and higher efficiency than the current methods.

  • Beyond metrics
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to describe an approach to developing a makerspace assessment plan. This approach focuses on connecting organizational and service point mission statements with outcome-based assessment plan goals, strategies, methods, and success measures. Design/methodology/approach This paper will outline the steps taken by an academic research library to design an outcomes-based assessment plan that monitors the human ecology of a makerspace. The paper includes a history of the space, the role of the library within the campus makerspace environment, the connection between mission statements and assessment plans, and how that connection can facilitate and drive space and service design. Findings Designing assessment plans that are centered on a makerspace mission statement can ensure that progress toward fulfilling the mission, values, and goals of the space is constantly monitored. Originality/value Academic library makerspace assessment literature is still in its infancy. This paper seeks to contribute to the literature on academic library makerspace management and stewardship.

  • Collaborative matrix factorization mechanism for group recommendation in
           big data-based library systems
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose Academic groups are designed specifically for researchers. A group recommendation procedure is essential to support scholars’ research-based social activities. However, group recommendation methods are rarely applied in online libraries and they often suffer from scalability problem in big data context. The purpose of this paper is to facilitate academic group activities in big data-based library systems by recommending satisfying articles for academic groups. Design/methodology/approach The authors propose a collaborative matrix factorization (CoMF) mechanism and implement paralleled CoMF under Hadoop framework. Its rationale is collaboratively decomposing researcher-article interaction matrix and group-article interaction matrix. Furthermore, three extended models of CoMF are proposed. Findings Empirical studies on CiteULike data set demonstrate that CoMF and three variants outperform baseline algorithms in terms of accuracy and robustness. The scalability evaluation of paralleled CoMF shows its potential value in scholarly big data environment. Research limitations/implications The proposed methods fill the gap of group-article recommendation in online libraries domain. The proposed methods have enriched the group recommendation methods by considering the interaction effects between groups and members. The proposed methods are the first attempt to implement group recommendation methods in big data contexts. Practical implications The proposed methods can improve group activity effectiveness and information shareability in academic groups, which are beneficial to membership retention and enhance the service quality of online library systems. Furthermore, the proposed methods are applicable to big data contexts and make library system services more efficient. Social implications The proposed methods have potential value to improve scientific collaboration and research innovation. Originality/value The proposed CoMF method is a novel group recommendation method based on the collaboratively decomposition of researcher-article matrix and group-article matrix. The process indirectly reflects the interaction between groups and members, which accords with actual library environments and provides an interpretable recommendation result.

  • eReadiness of public university libraries in Malawi to use mobile phones
           in the provision of library and information services
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to present findings of a study conducted to determine eReadiness status of public university libraries in Malawi to use mobile phones in the provision of library and information services. Design/methodology/approach The researcher carried out in-depth semi-structured interviews with university/college librarians and information and communications technology (ICT) directors using interview guides. Students were also administered with a survey questionnaire that contained closed- and some open-ended questions. Proceedings of the interviews were recorded using a tape recorder whilst backup notes were recorded in a notebook. Qualitative data were transcribed and analysed using NVivo software whilst quantitative data were analysed using SPPS. Findings The study findings revealed that institutions studied had the ICT infrastructure necessary for offering library and information services on the mobile phone platform. Moreover, students had mobile phones which were connected to internet to facilitate their access to services offered. However, the institutions covered by this study did not have operational ICT policies to govern the operations of library and information services offered through mobile phones although draft ICT policies were available. The study further concluded that though the human resources required to manage the provision of library and information services through mobile phones in the institutions studied were available, they did not have the necessary skills and numbers to provide quality services. Other findings revealed that attitudes of library staff and students to the offering and access to services through mobile phones were positive. The study also revealed that there are some factors that could impact the offering of library services through mobile phones. Research limitations/implications Although Malawi has four public universities, this study only focused on three of them. Moreover, academic staff is another important user group of academic libraries. In this case, findings reported in this paper only focus on students. This implies that library’s readiness to offer services through mobile phones to this group remains unknown hence may have to be covered by future studies. Much as the study incorporated a quantitative strand in addition to the qualitative one, it neither involved theory testing nor confirmation as is the case with other related studies. This implies that the two theories used in this study (the unified theory of acceptance and use of technology and the technology-organisation-environment) were not used in the strict sense, which is empirical at the core, but rather to put the problem studied in the context of other related studies. Practical implications The findings have practical implications in that they can be used for planning the implementation of library and information services through mobile phones in public university libraries in Malawi. Other related institutions can also use the findings as a reference point in planning the implementation of similar services. Originality/value Studies relating to the use of mobile phones in the delivery of library and information services have not been conducted in public universities in Malawi. Findings of this study will, therefore, inform researchers intending to conduct similar or related studies not only in public universities in Malawi but other related institutions as well.

  • Comparing the determinants of non-MOOC and MOOC continuance intention in
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose Massive open online courses (MOOCs) differ from non-MOOC e-learning platforms mainly in terms of degree of openness, with MOOCs designed to maximize learner access and interaction. The purpose of this paper is to propose a new research model to explore intention to continue to use MOOCs from the perspectives of openness and interactivity, based on related theories and dimensions from previous research. Design/methodology/approach In order to evaluate the effectiveness of the MOOC platform, two online survey questionnaires were developed and e-mailed to the all of the university students in Taichung, Taiwan. The first one and second one are the same except the construct openness. The first one was delivered in late 2015 while the second one was delivered in the middle 2016. After the authors eliminated incomplete responses and duplicates, 995 and 854 usable responses from platform users remained, respectively, and were used to test the relationships in the model. Findings The model can account for more than 75 percent of the variance in continuance intention. The research results affirm prior findings that satisfaction has a strong direct influence on intention. Among the three interaction factors, human-message interaction on the platform has the strongest effect on satisfaction. This study found that the effects of interactions and motivation on MOOC and non-MOOC platforms were consistent and similar. Moreover, perceived openness was found to influence usage intention but its effects were relative low. Originality/value The model demonstrated good explanatory power for continued intention in the context of MOOCs. This study provides a better understanding of the relationships among interactions, motivations, perceived openness, and continuance intention.

  • Long-term preservation of big data: prospects of current storage
           technologies in digital libraries
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to investigate the prospects of current storage technologies for long-term preservation of big data in digital libraries. Design/methodology/approach The study employs a systematic and critical review of the relevant literature to explore the prospects of current storage technologies for long-term preservation of big data in digital libraries. Online computer databases were searched to identify the relevant literature published between 2000 and 2016. A specific inclusion and exclusion criterion was formulated and applied in two distinct rounds to determine the most relevant papers. Findings The study concludes that the current storage technologies are not viable for long-term preservation of big data in digital libraries. They can neither fulfil all the storage demands nor alleviate the financial expenditures of digital libraries. The study also points out that migrating to emerging storage technologies in digital libraries is a long-term viable solution. Research limitations/implications The study suggests that continuous innovation and research efforts in current storage technologies are required to lessen the impact of storage shortage on digital libraries, and to allow emerging storage technologies to advance further and take over. At the same time, more aggressive research and development efforts are required by academics and industry to further advance the emerging storage technologies for their timely and swift adoption by digital libraries. Practical implications The study reveals that digital libraries, besides incurring significant financial expenditures, will suffer from potential loss of information due to storage shortage for long-term preservation of big data, if current storage technologies are employed by them. Therefore, policy makers and practitioners should meticulously choose storage technologies for long-term preservation of big data in digital libraries. Originality/value This type of holistic study that investigates the prospects of magnetic drive technology, solid-state drive technology, and data-reduction techniques for long-term preservation of big data in digital libraries has not been conducted in the field previously, and so provides a novel contribution. The study arms academics, practitioners, policy makers, and industry with the deep understanding of the problem, technical details to choose storage technologies meticulously, greater insight to frame sustainable policies, and opportunities to address various research problems.

  • Digital preservation at Big Data scales: proposing a step-change in
           preservation system architectures
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to consider how digital preservation system architectures will support business analysis of large-scale collections of preserved resources, and the use of Big Data analyses by future researchers. Design/methodology/approach This paper reviews the architecture of existing systems, then discusses experimental surveys of large digital collections using existing digital preservation tools at Big Data scales. Finally, it introduces the design of a proposed new architecture to work with Big Data volumes of preserved digital resources – also based upon experience of managing a collection of 30 million digital images. Findings Modern visualisation tools enable business analyses based on file-related metadata, but most currently available systems need more of this functionality “out-of-the-box”. Scalability of preservation architecture to Big Data volumes depends upon the ability to run preservation processes in parallel, so indexes that enable effective sub-division of collections are vital. Not all processes scale easily: those that do not require complex management. Practical implications The complexities caused by scaling up to Big Data volumes can be seen as being at odds with preservation, where simplicity matters. However, the sustainability of preservation systems relates directly to their usefulness, and maintaining usefulness will increasingly depend upon being able to process digital resources at Big Data volumes. An effective balance between these conflicting situations must be struck. Originality/value Preservation systems are at a step-change as they move to Big Data scale architectures and respond to more technical research processes. This paper is a timely illustration of the state of play at this pivotal moment.

  • Antecedents and consequences of social networking site knowledge sharing
           by seniors
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose Understanding elders’ experience and knowledge-sharing behaviors online have become significant issues in this aging society. In this study, the purpose of this paper is to summarize and validate the factors that influence the intention of elders to share knowledge online, and assess whether seniors’ knowledge-sharing behaviors affect their sense of meaning in life. Design/methodology/approach In total, 49 senior students were invited as participants to join the social networking site (SNS) and share knowledge on the platform. After a month of knowledge-sharing activities, questionnaires were distributed to all the participants. All the 49 participants returned completed questionnaires. To verify the results obtained via the above quantitative data analysis, follow-up interviews were conducted with one popular computer instructor and four seniors (who are experienced users of the SNS). Open-ended questions were employed to understand the motivations for sharing knowledge in a virtual community and the benefits obtained from sharing. Findings The results indicate that sharing vision, community identification, and social interaction ties are the main factors that influence the sharing of knowledge by seniors on SNSs. In addition, sharing knowledge on SNSs has a positive influence on seniors’ meaning in life. Follow-up interviews conducted also validate the results obtained. Originality/value Understanding elders’ experience and knowledge-sharing behaviors online have become significant issues in this aging society. It can not only benefit younger generations but also enable them to age gracefully. Rare SNSs similar to the one used in the study were found on the Facebook during our research.

  • Apps on laps: digital storytimes in public libraries in Aotearoa New
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to report on a small, exploratory research project focusing on librarian and parent/caregiver opinions of, and reactions to, the use of digital media and technology in public library storytimes for preschool children in Aotearoa New Zealand. Design/methodology/approach Telephone interviews with librarians and an online survey of parent/caregivers were undertaken. Findings The research found a mixed response to digital storytimes. Those who had not attended or presented digital storytime sessions were largely opposed to the practice, while those who had participated in a storytime using digital media generally held more positive views. Key concerns were focused on the amount of screentime young children should have and a lack of human interaction. Supporters appreciated the introduction of some basic digital literacy skills and the variety that technology could bring to storytime sessions. Research limitations/implications Both samples were small and self-selecting. The use of an online survey meant a bias in the sample toward those with access to appropriate information communication technology as well as a self-selection bias. Practical implications The paper suggests some developments in practice and approach if librarians are going to play the role of media mentors in their communities. Originality/value This is the first study focusing on the development of digital storytimes in Aotearoa New Zealand and adds to knowledge and understanding of key stakeholder views of the inclusion of digital media and technology in public library programming for young children.

  • Public library mobile apps in Scotland: views from the local authorities
           and the public
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to examine current public library apps in Scotland and assess Scottish public library users’ opinions of those apps. Design/methodology/approach Two qualitative and quantitative surveys were conducted. One survey was distributed to each Scottish local authority, the entities responsible for public libraries and Scotland. The second survey was made available to the public. The results were analysed with nonparametric statistics and content analysis. Findings All 32 authorities responded. In all, 17 authorities had an app, two had one in development, and 13 had none. Offering an alternative means of communication to patrons was the main reason for providing an app, while cost and low priority were the main reasons provided against app provision. Authorities were satisfied with the core services offered in their apps, but less so with others. No authorities had consulted the public regarding app provision. The public (n=185), while satisfied with current library apps, criticised the complex procedures required to access external services. Patrons from authorities without an app stated interest in apps. Research limitations/implications It is vital for public libraries to implement at least core services that are optimised for mobile devices. They should consult with the public before and throughout the development process to ensure they are happy with the implementation. Originality/value This is the first known study to explore public library app use in Scotland as well as one of the first in public library app use worldwide.

  • Differences between experts and novices when reading with navigational
           table of contents
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to examine the difference between experts and novices when reading with navigational table of contents (N-TOC). Experts refer to readers with high level of domain knowledge; novices refer to readers with low level of domain knowledge. Design/methodology/approach The authors performed a controlled experiment of three reading tasks (including fact finding task, partial understanding task, and full-text understanding task) on an N-TOC system for 35 post-graduates of Wuhan University who have rich experience in reading with N-TOC. Participants’ domain knowledge was measured by pre-experiment questionnaires; reading performance data including score, time, navigation use, and evaluation of N-TOC were collected. Findings The results showed that there was significant difference in neither navigation use nor participants’ evaluation, but domain experts performed significantly better in both score and time of all tasks than domain novices, which revealed an “illusion of control” phenomenon that rich experience in reading with N-TOC enabled domain novices to achieve the same performance as domain experts. In addition, this research found that N-TOC was not suitable for domain novices to solve full-text understanding task because of “cognitive overload” phenomenon. Originality/value This study makes a good contribution to the literature on the effect of domain knowledge on reading performance during N-TOC reading and how to provide better digital reading service in the field of library science and information science.

    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to compare the content of Web of Science (WoS) and Google Scholar (GS) by searching the interdisciplinary field of climate and ancient societies. The authors aim at analyzing the retrieved documents by open availability, received citations, co-authors and type of publication. Design/methodology/approach The authors searched the services by a defined set of keyword. Data were retrieved and analyzed using a variety of bibliometric tools such as Publish or Perish, Sci2Tool and Gephi. In order to determine the proportion of open full texts based on the WoS result, the authors relocated the records in GS, using an off-campus internet connection. Findings The authors found that the top 1,000 downloadable and analyzable GS items matched poorly with the items retrieved by WoS. Based on this approach (subject searching), the services appeared complementary rather than similar. Even though the first search results differ considerably by service, almost each single WoS title could be located in GS. Based on GS’s full text recognition, the authors found 74 percent of WoS items openly available and the citation median of these was twice as high as for documents behind paywalls. Research limitations/implications Even though the study is a case study, the authors believe that findings are transferable to other interdisciplinary fields. The share of freely available documents, however, may depend on the investigated field and its culture toward open publishing. Practical implications Discovering the literature of interdisciplinary fields puts scholars in a challenging situation and requires a better understanding of the existing infrastructures. The authors hope that the paper contributes to that and can advise the research and library communities. Originality/value In light of an overwhelming and exponentially growing amount of literature, the bibliometric approach is new in a library context.

  • No strings attached' Challenges and successes in creating a flexible,
           wire-free active learning classroom
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose This paper serves as a case study, detailing an academic library’s three-year process of redesigning, implementing, and using a library electronic classroom. The purpose of this paper is to share the challenges and successes of a library’s attempt to create a high-tech space that both accommodates active learning and is entirely flexible and free of wires. The paper provides technical details for implementing features such as wireless screen sharing and offers practical advice for librarians who are creating new teaching and learning spaces at their institutions. Design/methodology/approach This is a descriptive case study, which details the lessons learned in implementing an active learning space that incorporates technology such as wireless display to multiple screens. Findings There are still major challenges in having a truly wire-free classroom including authentication policies, wireless display technology, instructor’s station mobility, and student laptop control. Successes include flexible furniture, battery-power management solutions, and using multiple wireless devices in a single room. Practical implications Practical implications of this paper include recommendations for planning this type of upgrade in a library electronic classroom. Originality/value The unique feature of this case was the effort to combine the mobile features of a flexible learning space with some of the robust technology of a hardwired active learning classroom. This paper features technical details beyond what can be found in the library literature. For example, very little has been written about the issues involved in wirelessly displaying a computer screen to multiple devices in a classroom.

  • The comparison of thesaurus and ontology
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to investigate indexers’ evaluation on the usability of ontology vs thesaurus in representation of concepts and semantic relations. To do so, “searching” category of ASIS&T thesaurus was selected and ASIS&TOnto was built based on it. Design/methodology/approach The usability examination method is used in order to compare the two semantic tools. Nine indexers were recruited as participants, who were proficient in English language, had experience in using the thesaurus and all had successfully passed the course of “information representation.” They were asked to think aloud while working with the tools and to answer a semi-structured interview. The data gathering was continued until it reached its saturation point. Findings The results of this study revealed that the definitions and scope notes represented in indexing tools such as thesauri and ontologies have an important role in improvement of indexers’ understanding. On comparing the hierarchical relations, results show that converting the structure of hierarchical relationships of ASIS&T thesaurus can enhance the indexers understanding of them, and also enriching the associative relations of ASIS&T thesaurus can cause indexers to have a better understanding and evaluation of the presented concepts and relations. Originality/value This study shares our findings on the usability of ASIS&T thesaurus as a core set of vocabulary for building a “searching” domain as a prototype ontology in the area of library and information science and provides the indexers viewpoints of the two semantic tools in this area.

    • Pages: 18 - 28
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 18-28, March 2018.
      Purpose The subject of this paper is the application of holograms in cultural institutions. The purpose of this paper is to define the potential areas of hologram use in libraries, particularly in education and promotion, and also in services. Design/methodology/approach The method of analysis and criticism of literature was used. Based on a search conducted through Google Scholar for the 2006-2016 period, the current state of research on the use of holograms in cultural institutions was established. Subsequently, in order to find examples of hologram use in libraries, museums, galleries, and social organizations, an established set of queries was used to systematically search network resources using global search engines and metasearch engines. The initial list of results was narrowed down to the most relevant. On the basis of the above fact, the main areas of hologram use in cultural institutions were defined and examples of best practices were selected according to chosen criteria. The comparative method then was used to determine potential areas of application of holographic techniques in libraries. Finally, SWOT analysis – the situational analysis method known to management sciences – was used to determine opportunities and threats related to the use of holograms in cultural institutions. Findings Holograms have broad potential use in libraries that is even broader than initially assumed because they are not limited to education, promotion and services, and can also be used in documentation, research and exhibitions. The use of holograms can bring many benefits, but it is also associated with certain risks that need to be considered. Practical implications The results can be widely used in practice as a framework for the implementation of holographic techniques in libraries. Social implications The paper can help initiate debate on the opportunities and risks of using holograms in cultural institutions. Originality/value The issue of the use of holograms has not yet been widely discussed in library and information science scientific journals.

  • Student responses to an animated character in information literacy
    • Pages: 29 - 42
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 29-42, March 2018.
      Purpose This paper reports on a grant-funded project to create a hand-drawn, custom-made animated character named Jasmyn. Drawing on animation theory, the purpose of this paper is to use qualitative research to investigate student responses to the medium of animation, the character’s design, and three presentation strategies. Design/methodology/approach The researchers held three student focus groups to investigate the following research questions: Will students endorse animation as a medium for library instructional videos on the grounds of its entertaining, subversive, or playful qualities' Is Jasmyn designed and written in a way that engages students and compels them to respond to her as a character' How will students respond to three presentation strategies: a lecture-style video, a video with supplemental animations, and a real-time, interactive lesson' Findings The researchers found that students expressed broad enthusiasm for animation as a medium, though responses to Jasmyn’s personality were mixed. The only presentation strategy that prompted unique responses was the interactive session, although all three focus groups provided revealing commentary about online learning. Students also identified aspects of the animation and character that could be improved, and reflected on ways Jasmyn might be integrated into online learning. Research limitations/implications This study, performed as part of a pilot project, was deliberately small in scale. Clearer implications would emerge from repetition with a larger group of students. Originality/value Jasmyn may be the only hand-drawn, custom-made animated character created for library instruction. No research studies on the use of animation in libraries have been published to date.

  • The application of near-automated georeferencing technique to a strip of
           historic aerial photographs in GIS
    • Pages: 43 - 56
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 43-56, March 2018.
      Purpose The purpose of this paper is to describe the procedure for near-automation of the most commonly used manual georeferencing technique in a desktop GIS environment for historic aerial photographs strip in library archives. Design/methodology/approach Most of the archived historic aerial photography consists of series of aerial photographs that overlap to some extent, as the optimal overlap ratio is known as 60 percent by photogrammetric standard. Therefore, conjugate points can be detected for the overlapping area. The first image was georeferenced manually by six-parameter affine transformation using 2013 National Agriculture Imagery Program images as ground truths. Then, conjugate points were detected in the first and second images using Speeded Up Robust Features and Random Sample Consensus. The ground space coordinates of conjugate points were estimated using the first image’s six parameters. Then the second image’s six parameters were calculated using conjugate points’ ground space coordinates and pixel coordinates in the second image. This procedure was repeated until the last image was georeferenced. However, error accumulated as the number of photographs increased. Therefore, another six-parameter affine transformation was implemented using control points in the first, middle, and last images. Finally, the images were warped using open source GIS tools. Findings The result shows that historic aerial strip collections can be georeferenced with far less time and labor using the technique proposed compared with the traditional manual georeferencing technique in a desktop GIS environment. Research limitations/implications The suggested approach will promote the usage of historic aerial photographs for various scientific purposes including land use and land cover change detection, soil erosion pattern recognition, agricultural practices change analysis, environmental improvement assessment, and natural habitat change detection. Practical implications Most commonly used georeferencing procedures for historic aerial photographs in academic libraries require significant time and effort for manual measurement of conjugate points in the object images and the ground truth images. By maximizing the automation of georeferencing procedures, the suggested approach will save significant time and effort of library workforce. Social implications With the suggested approach, large numbers of historic aerial photographs can be rapidly georeferenced. This will allow libraries to provide more geospatial data to scientific communities. Originality/value This is a unique approach to rapid georeferencing of historic aerial photograph strips.

  • Improving the visibility of library resources via mapping library subject
           headings to Wikipedia articles
    • Pages: 57 - 74
      Abstract: Library Hi Tech, Volume 36, Issue 1, Page 57-74, March 2018.
      Purpose Linking libraries and Wikipedia can significantly improve the quality of services provided by these two major silos of knowledge. Such linkage would enrich the quality of Wikipedia articles and at the same time increase the visibility of library resources. To this end, the purpose of this paper is to describe the design and development of a software system for automatic mapping of FAST subject headings, used to index library materials, to their corresponding articles in Wikipedia. Design/methodology/approach The proposed system works by first detecting all the candidate Wikipedia concepts (articles) occurring in the titles of the books and other library materials which are indexed with a given FAST subject heading. This is then followed by training and deploying a machine learning (ML) algorithm designed to automatically identify those concepts that correspond to the FAST heading. In specific, the ML algorithm used is a binary classifier which classifies the candidate concepts into either “corresponding” or “non-corresponding” categories. The classifier is trained to learn the characteristics of those candidates which have the highest probability of belonging to the “corresponding” category based on a set of 14 positional, statistical, and semantic features. Findings The authors have assessed the performance of the developed system using standard information retrieval measures of precision, recall, and F-score on a data set containing 170 FAST subject headings manually mapped to their corresponding Wikipedia articles. The evaluation results show that the developed system is capable of achieving F-scores as high as 0.65 and 0.99 in the corresponding and non-corresponding categories, respectively. Research limitations/implications The size of the data set used to evaluate the performance of the system is rather small. However, the authors believe that the developed data set is large enough to demonstrate the feasibility and scalability of the proposed approach. Practical implications The sheer size of English Wikipedia makes the manual mapping of Wikipedia articles to library subject headings a very labor-intensive and time-consuming task. Therefore, the aim is to reduce the cost of such mapping and integration. Social implications The proposed mapping paves the way for connecting libraries and Wikipedia as two major silos of knowledge, and enables the bi-directional movement of users between the two. Originality/value To the best of the authors’ knowledge, the current work is the first attempt at automatic mapping of Wikipedia to a library-controlled vocabulary.

  • Where are the sleeping beauties and princes in educational technology
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to introduce an affective computing-based method of identifying sleeping beauties and their princes in five educational technology journals. Design/methodology/approach This study develops an information technology-based methodology to analyze sleeping beauties in the field of educational technology. The authors seek to determine the characteristics of studies which trigger the awakening of sleeping beauties (called “princes”). The keywords and Hirsch index (H-index) are used as two essential analysis indicators. Findings Between 2000 and 2015, these five journals included 7,864 articles with a total of 77,700 citations and 24,312 keywords. This study identified articles as being in deep sleep (75.7 percent), less deep sleep (14.7 percent), and awakening (5.5 percent) states. According to the analytical results, 431 of 7,864 articles are qualified as “sleeping beauties.” Of the 431 sleeping beauties identified, 232 articles were awakened by trend princes, while 286 were awakened by H-index princes. A total of 128 sleeping beauties were awakened by both prince types. Besides, impact factors (IFs) of journals do not have a significant effect on the number of sleeping articles. Research limitations/implications There are two main research limitations in this study. The first one is the amount of target journals. Only five well-known educational technology journals are analyzed in this research. There may be more valuable sleeping publications in other journals not been found. The second limitation is that the authors merely pick up the lead author of citing papers as the indicator to determine the H-index prince. The contributions of the rest of authors are not taken are not taken into consideration. These limitations should be further studied. Originality/value To the knowledge, this study is the first one reporting the identification of sleeping beauty and princes in educational technology field. Furthermore, the authors devise an informational method to determine sleeping publications, sleeping beauty, and princes. A systematic analysis of five well-known journals in the field of educational technology field confirms the existence of “sleeping beauties.” It is reported that improvements to a journal’s IF are positively correlated to increased numbers of sleeping beauties being awakened. To reduce the number of such articles, or to reduce the overall sleeping duration, journal editors should not only seek to raise the journal’s IF, but also strategically select keywords for maximum visibility, and promote articles to high H-index authors.

  • Human behavior analysis under financial information science
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose The purpose of this paper is to investigate the relationships among corporate social responsibility (CSR), analyst forecast accuracy and firms’ earnings management behavior using US-based firms. Design/methodology/approach The authors use the Kinder, Lydenberg, Domini (KLD) database to construct CSR performance scores and divide all firms into ten groups from high to low as a proxy for CSR performance. The authors obtained an initial sample of 33,364 firm-year observations from 1991 to 2012. Filtering for records which exist in the KLD, Compustat, and Center for Research in Security Prices databases lefts a total of 16,807 firm-year observations and CSR evaluation reports for 5,896 firms. Findings The authors find that high CSR-score firms have lower rates of analyst forecast error than their low CSR-score counterparts, suggesting that CSR performance is a useful means of forecasting earnings. Furthermore, firms with better CSR performance have significantly lower accrual-based earnings management behavior. However, the level of the manipulation behavior of real earnings management (REM) activities increased significantly in better CSR firms, suggesting that high CSR-score firms substituted REM methods for accrual-based methods. REM methods are consistent with the stipulations of the Sarbanes-Oxley Act and allow high CSR-score firms to better manipulate earnings behavior. These results hold after the authors control for various factors related to firm financial characteristics. Originality/value Overall, the findings have important implications for investors and regulators to more easily assess firms’ earnings manipulation behavior and earnings stability under CSR performance and financial information in financial markets.

  • Library personalized recommendation service method based on improved
           association rules
    • Abstract: Library Hi Tech, Ahead of Print.
      Purpose Nowadays, database management system has been applied in library management, and a great number of data about readers’ visiting history to resources have been accumulated by libraries. A lot of important information is concealed behind such data. The purpose of this paper is to use a typical data mining (DM) technology named an association rule mining model to find out borrowing rules of readers according to their borrowing records, and to recommend other booklists for them in a personalized way, so as to increase utilization rate of data resources at library. Design/methodology/approach Association rule mining algorithm is applied to find out borrowing rules of readers according to their borrowing records, and to recommend other booklists for them in a personalized way, so as to increase utilization rate of data resources at library. Findings Through an analysis on record of book borrowing by readers, library manager can recommend books that may be interested by a reader based on historical borrowing records or current book-borrowing records of the reader. Research limitations/implications If many different categories of book-borrowing problems are involved, it will result in large length of encoding as well as giant searching space. Therefore, future research work may be considered in the following aspects: introduce clustering method; and apply association rule mining method to procurement of book resources and layout of books. Practical implications The paper provides a helpful inspiration for Big Data mining and software development, which will improve their efficiency and insight on users’ behavior and psychology. Social implications The paper proposes a framework to help users understand others’ behavior, which will aid them better take part in group and community with more contribution and delightedness. Originality/value DM technology has been used to discover information concealed behind Big Data in library; the library personalized recommendation problem has been analyzed and formulated deeply; and a method of improved association rules combined with artificial bee colony algorithm has been presented.
