  • A Library’s Information Retrieval System (In)Effectiveness: Case
    • Authors: Robert Marijan, Robert Leskovar
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose The purpose of this research is (1) evaluating the effectiveness of the information retrieval component of a daily newspaper publisher’s integrated library system (ILS) in comparison with the commercial and open source alternatives and (2) observing the impact of the scale of metadata, generated daily by library administrators, on retrieved result sets. Design/methodology/approach In Experiment 1, we compared the result sets of the information retrieval system (IRS) component of the publisher’s current ILS and the result sets of proposed ones with human-assessed relevance judgment set. In Experiment 2, we compared the performance of proposed IRS components with the publisher’s current production IRS, using result sets of current IRS classified as relevant. Both experiments were conducted using standard information retrieval evaluation methods: precision, recall, precision at k, f-measure, mean average precision and 11-point interpolated average precision. Findings Results showed that (1) in Experiment 1, the publisher’s current production ILS ranked last of all participating information retrieval systems when compared to a relevance document set classified by the senior library administrator, and (2) in Experiment 2, the tested information retrieval components’ request handlers that used only automatically generated metadata performed slightly better than request handlers that used all of the metadata fields. Therefore, regarding the effectiveness of information retrieval, the daily human effort of generating the publisher’s current set of metadata attributes is unjustified. Research limitations/implications The experiments’ collections contained Slovene language with large number of variations of the forms of nouns, verbs and adjectives. The results could be different if the experiments’ collections contained languages with different grammatical properties. Practical implications We have confirmed, using standard information retrieval methods, that the information retrieval component used in the publisher’s current ILS, could be adequately replaced with an open source component. Based on our research, the publisher could incorporate the suggested open source information retrieval components in practice. In the research, we have described the methods that can be used by libraries for evaluating the effectiveness of the information retrieval of their ILSs. Originality/value The paper provides a framework for the evaluation of an ILS’s information retrieval effectiveness for libraries. Based on the evaluation results, the libraries could replace the information retrieval components if their current information system setup allows it.

  • Usability Study of the Mobile Library App: An Example from Chongqing
    • Authors: Qunyi Wei, Zhaoxin Chang, Qin Cheng
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose The purpose of the evaluation described in this study was to determine the usability of the mobile library App of Chongqing University and to provide recommendations for improving the experience of App users. Design/methodology/approach Usability testing, which comprised pre-test questionnaires, accomplishing tasks, and post-test surveys, was conducted in this study. The effectiveness and efficiency of the App, as well as user satisfaction with it, were measured. Findings The mobile App was proven effective but the efficiency of the App required improvement. With regard to user satisfaction, the factors “clarity” and “usefulness” received the lowest and highest scores, respectively. The descriptions of mobile services were unclear and confused users; nonetheless, the services provided by this App were appealing and useful to the users. Based on the measured user experience, this study proposed several recommendations for enhancing the usability of the App. Originality/value An increasing number of domestic and foreign libraries have begun to use mobile Apps to provide new services to patrons. In the future, smartphones are likely to become crucial to the delivery of information services. Given the extensive use of the Super Star Mobile Library system adopted by Chongqing University Library in China, the usability of such a system must be investigated. Improving the usability of the mobile library App can help enhance user experience.

    • Authors: Jing Chen, Quan Lu
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose This paper proposed a novel method to analysis TOC (Table of Contents) in Chinese books automatically based on the hierarchy organization rules which gained by investigation. Design/methodology/approach This paper analyzed the main literature in this field first, then hierarchy organization rules of Chinese book TOC were generated and the method parsing TOC automatically based on these rules was proposed. A prototype system implementing our method was also developed. The method was evaluated through processing a corpus on the prototype system, and the results were checked with calculation of precision and recall. Findings The experiment result illustrated the superiority (extensive application, recall is 95.34% and precision is 94.44%) of our method. Practical implications The result can helps Chinese libraries deal with electronic texts from four aspects. First, it can be used to complement or enhance current digitization and OCR methods and cut the financial and labor cost of Chinese libraries. Second, it can help libraries to keep information on indexing words as well as chapters, sections and subsections in Chinese book databases, which ensures easy retrieval and extract any intended portion as demanded by user. Third, it helps to enrich the services and then enhances the user experiences in Chinese libraries. Fourth, it improves the specification and policy of digitalizing Chinese books. Originality/value The paper provided insight into the hierarchy organization of TOCs in Chinese books, the method based on the rules has extensive application than other methods. This method for Chinese book TOC automatic analysis is also as reference for English book TOC automatic analysis.

  • A Study on the User Evaluation for an RDA-based Korean Bibliography
           Retrieval System
    • Authors: Seulki Do, Sam G. Oh, Sungin Lee
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose This study attempts to validate the usefulness of Resource Description and Access (RDA) from user perspectives by implementing an RDA-based bibliographic retrieval system, and comparing it against two retrieval systems. Design/methodology/approach Surveys and interviews were conducted to gather responses from 20 subjects who used the systems. Usability was measured according to the following metrics: 1) search usefulness from search process and results; 2) search efficiency, measured in time and the number of steps involved; 3) general satisfaction for search results and process, and for information need; 4) satisfaction for search functionalities, with five sub-measures (usability of functions of search tool, appropriateness of search results, usability of additional information, usability of associative relations, and appropriateness of search categories); and 5) system convenience in terms of understandability and ease. Findings The survey results indicate that all but the satisfaction for appropriateness of search categories showed significant differences between the systems. The interviews show that the RDA system received from the subjects a more positive evaluation compared to the counterpart systems, in search usefulness, search efficiency, general search satisfaction, satisfaction for search functionalities. Practical implications Though a few organizations such as the Library of Congress in the U.S. have implemented RDA, no such endeavors have been undertaken in the context of Korean bibliography, and especially for the systematic validation of usability of such a system from user perspectives. Originality/value This is the first published study that validates the usefulness perceived by users of RDA in the context of Korean bibliography.

  • Beyond TIFF and JPEG2000: PDF/A as an OAIS Submission Information Package
    • Authors: Yan Han
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose The article is to introduce PDF/A to replace TIFF as the preferred file format for digitization of textual documents. In addition, PDF/A can be used as an OAIS submission information package (SIP) container to reduce digitization and digital preservation costs. Design/methodology/approach The author first reviewed the current digitization guidelines, the OAIS model and provides on an overview of the development PDF and PDF/A as international standards. Then literature review of the uses of PDF/A is presented. The author analyzed pitfalls of TIFFs as the preferred format for digitization, and showed how to use PDF/A to code digitization submission information packages. Findings TIFF file format has been the preferred master file format by FADGI digitization guidelines for the past 20 years. However, there are drawbacks of TIFF format. Literature reviews show that PDF/A has been the preferred standard for coding born-digital documents in court, government and business sectors. PDF/A-2 and PDF/A-3 are relatively new standards released after 2010. However, few understood the standards and have utilized the full potentials in digitization. The author shows that PDF/A can be used as an OAIS SIP container. Practical implications In order to delivery OAIS SIPs, current practices require a combination of files, directories, and various types of metadata. The author shows that PDF/A (PDF/A-2 and/or PDF/A-3) can be a better file format for textual document digitization with coding various types of metadata in XMP and arbitrary file/data can be coded in PDF/A-3. These features in PDF/A provide much better ways to deliver SIPs in a cost-efficient manner. Originality/value PDF/A has been recognized as the preferred standard for born-digital documents, but it has not been used as the preferred file format for digitized materials. The author recommends that 1) PDF/A with lossless JPX compressions as the prefered file format, and 2) PDF/A with lossless JPX compressions along with metadata/data as the preferred OAIS SIP container. As a result, the uses reduce costs in digitization and digital preservation and also increase productivity. The author recommends to update the national and international digitization practices using PDF/A.

  • A Multisource Book Review System for Reducing Information Overload and
           Accommodating Individual Styles
    • Authors: Gloria Yi-Ming Kao, Chi-Chieh Peng
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose This study evaluated the performance of the multi-source book review system (MBRS). MBRS was designed to reduce information overload using the Internet and to accommodate different learner preferences. Design/methodology/approach We experimentally compared MBRS with the Google search engine. MBRS first gathers reviews from online sources, such as bookstores and blogs. It reduces information overload through an advanced filtering and sorting algorithm and by providing a uniform user interface. MBRS accommodates different learning styles through various sort options and through adding video-mediated reviews. Findings Results indicate that, compared with Google, MBRS (a) reduces the information overload associated with searching for online book reviews, (b) increases users finding satisfactory book reviews, and (c) allows users to find reviews more quickly. In addition, more than half of the participants found video-mediated book reviews more appealing than traditional text-based reviews. Research limitations/implications Future studies might examine the effects of other recommendations or sorting methods to fit individual preferences in a more dynamic way. Practical implications This study assisted readers with a preference for visual information in locating reviews of personal interest in less time and with finding reviews more aligned with their individual learning preferences. Originality/value This study documents an innovative Website featuring video-mediated book reviews and other mechanisms to accommodate individual preferences. Search engine designers could integrate book reviews with different media types to reduce cognitive load allowing readers to focus attention on the reading task. Internet booksellers or library staff may use this as an effective means to enhance reading motivation.

  • Measuring Student Academic Technology Proficiency in the College Library
           [now “How do I send an Email?”: Technology Challenges for
           First-Year Students in the College Library]
    • Authors: Michelle Eichelberger, Bonnie Brubaker Imler
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose The study described in this paper aims to identify the ability of college freshmen to successfully use common academic software and manage files. Design/methodology/approach 39 college freshmen from three college campuses were recruited for the study. An online test environment and screen recording software were used to measure student proficiency in using PDFs, Microsoft Word, Microsoft PowerPoint, Microsoft Excel, Gmail, and Windows. Data were collected in September 2013. Findings Student use of academic technology is common, but their software skills are not comprehensive or deep. Students were most proficient at using PDFs and Microsoft Word. Microsoft Excel tasks were the most difficult for the students, and many struggled to use Gmail to compose a message and send an attachment. Students were able to open a PowerPoint document and view a slideshow, but they were less comfortable navigating the software’s printing environment. Originality/value Having concrete data about student technology skills, rather than anecdotal data from Reference Desk interactions, can help librarians design improved instruction and tutorials that target areas of student technology weakness.

  • Collaborative information seeking environments benefiting from holistic
    • Authors: Anika Meyer, Ina Fourie
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose To explore the value of utilising a holistic ergonomic approach, covering engineering, cognitive, and social perspectives, to cultivate beneficial and productive CIS systems and environments, specifically with regard to three main CIS pillars (control, communication and awareness). Design/methodology/approach A qualitative research approach, based on a selective corpus of CIS literature, was utilised to perform a content analysis to note if terms and concepts normally associated with engineering, cognitive and social ergonomics can be used to eliminate terms reflecting issues related to three CIS pillars (control, communication and awareness) that can benefit from a holistic ergonomic approach. Findings The content analysis revealed that a fairly extensive amount of holistic ergonomic terminology is prominent within the CIS literature, therefore establishing a connection between the two disciplines: Collaborative Information Seeking and Ergonomics. This suggests that CIS system issues could benefit from the insights of a holistic ergonomic approach. Research limitations/implications Since this is an exploratory study the scope of CIS literature utilised in the content analysis was limited to a selection considered most important by the authors; this should be supplemented by further research. Practical implications Intended to instigate interest in further exploration of the beneficial and productive implications and practical application of holistic ergonomics in designing CIS systems and environments. Originality/value This is the first research article in the LIS literature that explores the potential of utilising holistic ergonomics to cultivate CIS systems and environments.

  • The Use of Geographic Information System in the Development and
           Utilization of Ancient Local Chronicles
    • Authors: Suoling Zhu, Ping Bao
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose The purpose of this paper is to apply Geographic Information System (GIS) in the development and utilization of Chinese ancient local chronicles to achieve the mining and visualization of historical data about products distribution and dispersal in Products in Local Chronicles. Design/methodology/approach Using 1756 records of product-related location names in Products in Local Chronicles of Guangdong of the Qing dynasty, which are recognized by a name recognition system, as attribute data; taking the spatial data of Chinese administrative geography of the Qing dynasty in 1820 and the Historical Atlas of China as spatial data; connect the attribute data with relevant spatial data based on the table connection function of Arcmap in Arcgis8.3 to implement the data management, cartography and analysis. Findings The application of GIS in the development and utilization of ancient local chronicles was quite successful. With some thematic maps, knowledge about products distribution and dispersal in ancient books was vividly displayed so as to facilitate relevant researches. Research limitations/implications Only product-related location names inside China were analyzed, not other named entities in local chronicles; and only static visual display was achieved, not dynamic visual display. Historical maps of the world can be used to carry out the visualization of the products distribution and dispersal in the world, and even the visualization of other knowledge, such as poetries and songs scattered over many places in China. The process of products dispersal and the distribution of poetries and songs can be dynamically and visually displayed by pictures, audios, videos, multimedia, etc. Practical implications By using GIS in the development and utilization of Chinese ancient local chronicles, this paper explores a new way for the collation of ancient books and open up a new area for the research of digital humanities. Originality/value This is the first try about the application of GIS in the development and utilization of ancient local chronicles, and also the same of digital humanities research in the field of agricultural history.

  • An informetrics view of the relationship between Internet ethics, computer
           ethics and cyberethics
    • Authors: Omwoyo Bosire Onyancha
      Abstract: Library Hi Tech, Volume 33, Issue 3, September 2015.
      Purpose The paper sought to explore the differences and similarities between computer ethics, Internet ethics and cyberethics as reflected in the contents of the published literature as well as the search trends on Google. Design/methodology/approach The paper opted for an informetrics approach, and more specifically content analysis, to investigate the inter-relationships between computer ethics, Internet ethics and cyberethics. The data sources for this study included Google Trends, Google Scholar and the Web of Science (WoS) citation indexes. Different search queries were used, depending on the structure of each data source, to extract the relevant datasets. Findings Using different methods and techniques to analyse the data, the paper provides an alternative means of investigating relationships among concepts. The findings indicate that there is still no clear distinction between the concepts in terms of subject and title terms used to describe the published literature on the three concepts, as well as the research areas where the three concepts are applied. Going by the current trend, the paper envisages that cyberethics may, in the future, become a broader term to include computer ethics and Internet ethics. Research limitations/implications The data sources that were selected for the study might have not been comprehensive in the coverage of the published literature on the three concepts and therefore there is need for further research, which will expand the scope of the data sources. Practical implications The paper’s findings may apply in the practice of indexing and abstracting as well as thesaurus construction as far as the three terms are concerned. Originality/value The paper offers an alternative technique that can be used to investigate relationships among concepts. The value of the paper could include curriculum development of programmes dealing with ethical issues that arise when developing and using computers and related technologies.

  • An analysis of file format control in institutional repositories
    • Authors: Miquel Termens, Mireia Ribera, Anita Locher
      First page: 162
      Abstract: Library Hi Tech, Volume 33, Issue 2, June 2015.
      Purpose This study analyzes the file formats of the digital objects stored in two of the largest open access repositories in Spain, DDUB and TDX, and determines the implications of these formats for long-term preservation, focusing in particular on the different versions of PDF. Design/methodology/approach To be able to study the two repositories, we harvested all the files corresponding to every digital object and some of their associated metadata using the OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting) and OAI-ORE (Open Archives Initiative Object Reuse and Exchange) protocols. The file formats were analyzed with DROID software and some additional tools. Findings The results show that there is no alignment between the preservation policies declared by institutions, the technical tools available, and the actual stored files. Originality/value The results show that file controls currently applied to institutional repositories do not suffice to grant their stated mission of longterm preservation of scientific literature.

  • A RDF-based approach to metadata crosswalk for semantic interoperability
           at the data element level
    • Authors: Ya-Ning Chen
      First page: 175
      Abstract: Library Hi Tech, Volume 33, Issue 2, June 2015.
      Purpose This article proposes a Resource Description Framework (RDF)-based approach to transform metadata crosswalking from equivalent lexical element mapping into semantic mapping with various contextual relationships. RDF is used as a crosswalk model to represent the contextual relationships implicitly embedded between described objects and their elements, including semantic, hierarchical, granular, syntactic, and multiple object relationships to achieve semantic metadata interoperability at the data element level. Design/methodology/approach This article uses RDF to translate metadata elements and their relationships into semantic expressions, and also as a data model to define the syntax for element mapping. The feasibility of the proposed approach for semantic metadata crosswalking is examined based on two use cases – the Archives of Navy Ships Project and the Digital Artifacts Project of National Palace Museum in Taipei – both from the Taiwan E-Learning and Digital Archives Program. Findings As the model developed is based on RDF-based expressions, unsolved issues related to crosswalking, such as sets of shared terms, and contextual relationships embedded between described objects and their metadata elements could be manifested into a semantic representation. Corresponding element mapping and mapping rules can be specified without ambiguity to achieve semantic metadata interoperability. Research limitations/implications Five steps were developed to clarify the details of the RDF-based crosswalk. The RDF-based expressions can also serve as a basis from which to develop linked data and Semantic Web applications. More use cases including biodiversity artifacts of natural history museums and literary works of libraries, and conditions, constraints and cardinality of metadata data elements will be required to make revisions to fine tune the proposed RDF-based metadata crosswalk. Originality/value In addition to reviving contextual relationships embedded between described objects and their metadata elements, nine types of mapping rules were developed to achieve a semantic metadata crosswalk which will facilitate the design of related mapping software. Furthermore, the proposed approach complements existing crosswalking documents provided by authoritative organizations, and enriches mapping language developed by the CIDOC community.

  • A semi-automatic indexing system based on embedded information in HTML
    • First page: 195
      Abstract: Library Hi Tech, Volume 33, Issue 2, June 2015.
      Purpose This paper describes and evaluates the tool DigiDoc MetaEdit which allows the semi-automatic indexing of HTML documents. The tool works by identifying and suggesting keywords from a thesaurus according to the embedded information in HTML documents. This enables the parameterization of keyword assignment based on how frequently the terms appear in the document, the relevance of their position, and the combination of both. Design/methodology/approach In order to evaluate the efficiency of the indexing tool, the descriptors/keywords suggested by the indexing tool are compared to the keywords which have been indexed manually by human experts. To make this comparison a corpus of HTML documents are randomly selected from a journal devoted to Library and Information Science. Findings The results of the evaluation show that there: (1) is close to a 50% match or overlap between the two indexing systems, however if you take into consideration the related terms and the narrow terms the matches can reach 73%; and (2) the first terms identified by the tool are the most relevant. Originality/value The tool presented identifies the most important keywords in an HTML document based on the embedded information in HTML documents. Nowadays, representing the contents of documents with keywords is an essential practice in areas such as information retrieval and e-commerce.

  • Digital Disaster Management in Libraries in India
    • Authors: Parul Zaveri
      First page: 230
      Abstract: Library Hi Tech, Volume 33, Issue 2, June 2015.
      Purpose Disaster management is an issue that has received relatively little attention in libraries, particularly in India. With the growth in digital resources in libraries, it is necessary for librarians to understand and apply the ways of protecting digital data and the related equipment from disaster. The present paper addresses the issues related to digital data protection in libraries in India. It aims to investigate the perceptions of librarians about the probability of digital disasters happening in their libraries, and to assess the level of digital disaster preparedness among libraries Design/methodology/approach A questionnaire based survey of 276 libraries in the Western region of India was conducted to find out the digital data protection measures taken by them. The paper provides an overview and analysis of the general trends in digital data protection in these libraries. Findings The research results indicate that due to lack of knowledge about handling of digital data, and inadequate digital infrastructure setup in organisations, the chances of loss of digital data are high. However, common measures like taking backup of data manually are mostly followed by all libraries. The paper has identified the trends in protection of digital data, as well as the lacunae, in Indian libraries. Basic guidelines on digital data preservation are also presented in the paper. Practical implications The guidelines provided in the paper will be useful to any libraries to take measures for protection of the digital data. The libraries will be able to prepare their digital data protection plan and train the staff accordingly. Originality/value This paper is the first to address the issue of digital disaster management in libraries in India. It provides a detailed analysis of digital data protection measures taken by Indian libraries currently.

      Purpose The article is intended to use cloud storage in digital preservation by analyzing the pricing and data retrieval models. The author recommends strategies to minimize the costs and believes cloud storage is worthy of serious consideration. Design/methodology/approach Few articles have been published to show the uses of cloud storage in libraries. The cost is the main concern. An overview of cloud storage pricing shows a price drop once every 1 or 1.5 year. The author emphasize the data transfer-out costs and demonstrate a case study. Comparisons and Analysis of S3 and Glacier have been conducted to show the differences in retrieval and costs. Findings Cloud storage solutions like Glacier can be very attractive for long-term digital preservation if data can be operated within the provider’s same data zone and data transfer-out can be minimized. Practical implications Institutions can benefit from cloud storage by understanding the cost models and data retrieval models. Multiple strategies are suggested to minimize the costs. Originality/value The article is intended to bridge the gap of uses of cloud storage. Cloud storage pricing especially data transfer-out pricing charts are presented to show the price drops over the past eight years. Costs and analysis of storing and retrieving data in Amazon S3 and Glacier are discussed in details. Comparisons of S3 and Glacier show that Glacier has uniqueness and advantages over other cloud storage solutions. Finally strategies are suggested to minimize the costs of using cloud storage. The analysis shows that cloud storage can be very useful in digital preservation.

      Abstract: Library Hi Tech, Volume 33, Issue 2, June 2015.
      Purpose This study aims to explore multiple factors affecting online library resource selection by undergraduate students. Three dimensions of factors are investigated including usefulness and ease-of-use, resource quality, and individual differences. Design/methodology/approach An instrument was developed to measure various aspect factors and online library resource use intention. A survey was administered to 332 undergraduate students. Quantitative analysis, including structural equation modelling, ANOVA, and t-tests, was used to statistically examine the effects of the identified eleven factors on the use intention of online library resources. Findings The findings indicated that both usefulness and ease-of-use positively influenced the undergraduates' use intention of online library resources. Also, five resource quality constructs – accessibility, credibility, coverage, currency, and format – were the determinants of online library resources use intention. Interestingly, the effect of accessibility was the strongest, while that of credibility was the weakest. In addition, this study found that familiarity with sources and use of good search skills had a significant effect on users’ use intention at the individual user level. Originality/value This study is one of the few studies investigating multiple factors comprehensively that influence online library resource selection.
