  • Semantic ontologies for multimedia indexing (SOMI)
    • Authors: Issam Bendib et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 206-218, June 2014. Purpose – The overwhelming speed and scale of digital media production greatly outpace conventional indexing methods by humans. The management of Big Data for e-library speech resources requires an automated metadata solution. The paper aims to discuss these issues. Design/methodology/approach – A conceptual model called semantic ontologies for multimedia indexing (SOMI) allows for assembly of the speech objects, encapsulation of semantic associations between phonic units and the definition of indexing techniques designed to invoke and maximize the semantic ontologies for indexing. A literature review and architectural overview are followed by evaluation techniques and a conclusion. Findings – This approach is only possible because of recent innovations in automated speech recognition. The introduction of semantic keyword spotting allows for indexing models that disambiguate and prioritize meaning using probability algorithms within a word confusion network. By the use of AI error-training procedures, optimization is sought for each index item. Research limitations/implications – Validation and implementation of this approach within the field of digital libraries still remain under development, but rapid developments in technology and research show rich conceptual promise for automated speech indexing. Practical implications – The SOMI process has been preliminarily tested, showing that hybrid semantic-ontological approaches produce better accuracy than semantic automation alone. Social implications – Even as testing proceeds on recorded conference talks at the University of Tebessa (Algeria), other digital archives can look toward similar indexing. This will mean greater access to sound file metadata. Originality/value – Huge masses of spoken data, unmanageable for a human indexer, can prospectively find semantically sorted and prioritized indexing – not transcription, but generated metadata – automatically, quickly and accurately.

  • Electronic theses and dissertations
    • Authors: Mildred Coates
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 285-299, June 2014. Purpose – The purpose of this paper is to examine two research questions: first, How do users in different locations find Auburn University Electronic Theses and Dissertations (ETDs)' Second, do users in different locations interact differently with the collection and, if so, how' Design/methodology/approach – Google Analytics data for user visits, landing pages, and page views were separated into groups based on user location. Visits data were also correlated with source (referring web site), and landing pages and page views were grouped by type. Findings – Most local users came to the repository via Auburn University web pages. This group usually landed on the collection home page and used internal navigation pages to find what they needed. Submission page views showed that most ETD depositors were local. Most out-of-state users came to the repository via web search engines. This group usually landed directly on bibliographic information pages for individual ETDs. They used internal navigation pages less frequently than local users. Users located within the state but outside of the local area interacted with the collection in a way that was intermediate between these two groups. Practical implications – Institutions interested in improving repository access for depositors will probably find it helpful to focus on in-state usage reports, while institutions seeking to improve access for end-users should exclude in-state users from their assessments. Originality/value – This is the first detailed examination of ETDs usage published since 2001 and shows how filtering tools available in Google Analytics allow comparisons of user behavior based on location and source (referring web site).

  • System design for location name recognition in ancient local chronicles
    • Authors: Ping Bao et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 276-284, June 2014. Purpose – The purpose of this paper is to present a system for recognition of location names in ancient books written in languages, such as Chinese, in which proper names are not signaled by an initial capital letter. Design/methodology/approach – Rule-based and statistical methods were combined to develop a set of rules for identification of product-related location names in the local chronicles of Guangdong. A name recognition system, with functions of document management, information extraction and storage, rule management, location name recognition, and inquiry and statistics, was developed using Microsoft's .NET framework, SQL Server 2005, ADO.NET and XML. The system was evaluated with precision ratio, recall ratio and the comprehensive index, F. Findings – The system was quite successful at recognizing product-related location names (F was 71.8 percent), demonstrating the potential for application of automatic named entity recognition techniques in digital collation of ancient books such as local chronicles. Research limitations/implications – Results suffered from limitations in initial digitization of the text. Statistical methods, such as the hidden Markov model, should be combined with an extended set of recognition rules to improve recognition scores and system efficiency. Practical implications – Electronic access to local chronicles by location name saves time for chorographers and provides researchers with new opportunities. Social implications – Named entity recognition brings previously isolated ancient documents together in a knowledge base of scholarly and cultural value. Originality/value – Automatic name recognition can be implemented in information extraction from ancient books in languages other than English. The system described here can also be adapted to modern texts and other named entities.

  • Digital library user privacy: changing librarian viewpoints through
    • Authors: Younghee Noh
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 300-317, June 2014. Purpose – The purpose of this paper is to research attempts to educate public librarians in the importance of user privacy issues and assist in reducing privacy violations by providing librarians with an educational program on the subject and measuring its effects. Design/methodology/approach – Research was conducted to examine the influence of education on library user privacy. An education program on the topic was developed and effects of the training were measured with pre- and post-seminar surveys. Findings – Concern for the protection of user privacy increased after the training, and its importance was rated higher as participating librarians became aware of the current likelihood of privacy violations, given the amount of user data libraries collect regularly. The demand for user privacy education also significantly increased after the librarian training course had been completed. Originality/value – This research verified that user privacy awareness can be greatly improved by educating librarians. The awareness change in librarians could greatly contribute to user protection and the basic mission of the library while controversial issues about privacy violation and filter bubbles are seriously discussed.

  • Exploring the effect of individual differences on user perceptions of
           print and electronic resources
    • Authors: Xianjin Zha et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 346-367, June 2014. Purpose – Individual differences are critical in determining how individuals think and behave in different ways. The purpose of this paper is to explore the effect of individual differences on users’ perceptions of print and electronic resources in terms of ease of use, usefulness and usage in the hopes that a better understanding of these effects can help Chinese university libraries to meet the diversified information needs of their users more specifically and appropriately so that the second-level capability divide and third-level outcome divide of library information resources can be much reduced. Design/methodology/approach – Data collected from 273 library users were used for data analysis. The independent samples t-test, one-way analysis of variance (ANOVA) and two-way ANOVA were employed. Meanwhile, the quantitative analysis is supplemented by the qualitative interviews which present richer data about the use of specific types of print and electronic resources. Findings – The effect of basic characteristics (gender, age, field) and experience (experience with library print resources, experience with library electronic resources, which library resources were used first) on users’ perceptions of print and electronic resources in terms of ease of use, usefulness and usage was explored and discussed. Meanwhile, the two-way interaction effect was examined and 13 significant interaction effects were presented. Originality/value – Building on the digital divide, this study examines ease of use, usefulness and usage in terms of individual differences which cover not only basic characteristics but also experience and two-way interaction, which the authors think provides a new view for library information resources research and practice alike in China.

  • Ensuring accessibility of electronic information resources for visually
           impaired people
    • Authors: Stefanus Andreas Kleynhans et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 368-379, June 2014. Purpose – The paper addresses the importance of clarifying terminology such as visually impaired and related terms before embarking on accessibility studies of electronic information resources in library contexts. Apart from briefly defining accessibility, the paper attempts to address the lack of in-depth definitions of terms such as visually impaired, blind, partially sighted, etc. that has been noted in the literature indexed by two major Library and Information Science (LIS) databases. The purpose of this paper is to offer a basis for selecting participants in studies of accessibility of electronic information resources in library contexts and to put discussions of such studies in context. Design/methodology/approach – Clarification of concepts concerning visual impairment following a literature survey based on searching two major databases in LIS. To put the discussion in context accessibility is also briefly defined. Findings – Although visually impaired and a variety of related terms such as blind, partially sighted, visually disabled, etc. are used in the LIS literature, hardly any attempt is made to define these terms in depth. This can be a serious limitation in web and electronic accessibility evaluations and the selection of participants. Practical implications – Clearly distinguishing between categories of visually impaired people and the ability of sight of participants is important when selecting participants for studies on accessibility for visually impaired people, e.g. the accessibility evaluation of web sites, digital libraries and other electronic information resources. Originality/value – The paper can make a contribution to the clarification of terminology essential for the selection of participants in accessibility studies, as well as enriching the literature on accessibility for visually impaired people in the context of LIS.

  • Mobile services at academic libraries: meeting the users’ needs'
    • Authors: Catharine Bomhold
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 336-345, June 2014. Purpose – The purpose of this paper is to describe how academic libraries in the USA have responded to the rapidly evolving mobile environment and to determine if there is a noticeable, comprehensive pattern to instituting mobile services. Design/methodology/approach – The researcher surveyed library mobile services of 73 academic libraries at Carnegie Foundation rated RU/VH institutions. Based on this survey, the paper describes the current state of mobile services at very high research universities. Findings – While most academic libraries at research universities have some sort of mobile presence, what is offered is highly varied and is not predictable. There are still many notable University libraries that have no mobile presence. Practical implications – This study highlights the inconsistent nature of mobile services at research universities and identifies best practices in place at others. Originality/value – This is the first study to employ the Carnegie Foundation ratings of the university in which the library functions.

  • The application profiles and development characteristics of library Open
           Source Software projects
    • Authors: Namjoo Choi
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 260-275, June 2014. Purpose – Little is known as to the breadth and diversity of Open Source Software (OSS) applications for libraries and the development characteristics that influence the sustainability and success of projects creating them. The purpose of this paper is to address this gap by analyzing a large sample of library OSS projects. Design/methodology/approach – A total of 594 library OSS projects (469 from SourceForge and 125 from Foss4lib) are classified by type and further differentiated and assessed across a number of criteria including, but not limited to, sponsorship status, license type, and development status. Findings – While various types of library OSS applications were found to be under development and in use, the results show that there has been a steady decrease in the number of projects initiated since 2009. Although sponsorship was significantly positively associated with several indicators of OSS project success, the proportion of sponsored projects was relatively small compared to the proportions reported in some other contexts. In total, 71 percent of the projects have a restrictive license scheme, suggesting that the OSS ideology is valued among library OSS projects. The results also indicate that library OSS projects exhibit several characteristics that differ from the traditional developer-oriented OSS projects in terms of their technical environment. Originality/value – This study, as the first of its kind, offers a broader, more quantitative picture of the state of library OSS applications as well as the development characteristics of projects developing them. Several implications for research and practice, and directions for future research are provided.

  • The Albert Einstein archives digitization project: opening hidden
    • Authors: Dalia Mendelsson et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 318-335, June 2014. Purpose – The purpose of this paper is to present the organizational and technological processes and strategic choices that led to the successful digitization project of the Albert Einstein Archives. Design/methodology/approach – This is a case study of the major challenges that were associated with the project. These include: the integration of the archives in the academic environment; the management of a project of such magnitude within the university organization and between different stakeholders and the technological aspects of the project and user experience. Findings – A digitization project requires not only the archival staff expertise but also information specialists, IT staff, analysts and usually the digitization staff for processing the archival material. Finding the common language between all the professionals involved as well as building a good strategic plan are the keys to a successful project. Research limitations/implications – The planning and implementation of such a project requires a significant budget, manpower project management, hardware, software and intra- and inter-organizational cooperation and coordination. Originality/value – The phenomenon of digitizing unique and exclusive archival data by universities is becoming an innovative contribution of hidden goods to the public at large. This paper offers strategic insights for the planning of similar digitizing projects, particularly in an academic environment.

  • Ontology-based text summarization. The case of Texminer
    • Authors: Pedro Hípola et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 229-248, June 2014. Purpose – The purpose of this paper is to look into the latest advances in ontology-based text summarization systems, with emphasis on the methodologies of a socio-cognitive approach, the structural discourse models and the ontology-based text summarization systems. Design/methodology/approach – The paper analyzes the main literature in this field and presents the structure and features of Texminer, a software that facilitates summarization of texts on Port and Coastal Engineering. Texminer entails a combination of several techniques, including: socio-cognitive user models, Natural Language Processing, disambiguation and ontologies. After processing a corpus, the system was evaluated using as a reference various clustering evaluation experiments conducted by Arco (2008) and Hennig et al. (2008). The results were checked with a support vector machine, Rouge metrics, the F-measure and calculation of precision and recall. Findings – The experiment illustrates the superiority of abstracts obtained through the assistance of ontology-based techniques. Originality/value – The authors were able to corroborate that the summaries obtained using Texminer are more efficient than those derived through other systems whose summarization models do not use ontologies to summarize texts. Thanks to ontologies, main sentences can be selected with a broad rhetorical structure, especially for a specific knowledge domain.

  • Populating the wilderness: crowdsourcing database of the smokies
    • Authors: Mark Patrick Baggett et al
      Abstract: Library Hi Tech, Volume 32, Issue 2, Page 249-259, June 2014. Purpose – Researchers at the University of Tennessee Libraries experimented with crowdsourcing to determine if contributions by members of the public could be utilized to add citations and subject tags to a new online bibliography, Database of the Smokies (DOTS: The paper aims to discuss this issue. Design/methodology/approach – The database is built in Drupal, an open source platform that provides a crowdsourcing mechanism. The public was offered the opportunity to create accounts and add content to DOTS. After three months, the project team performed a transaction log analysis of user submissions in order to determine whether an editorial process was necessary. Findings – This analysis revealed that 18 percent of database content was the result of crowdsourcing and that much of the content submitted by participants was either obscure or difficult to locate. The analysis also showed that while contributors added valuable citations, an editorial review process was necessary to ensure this crowdsourced content could be published in the database. In addition, contributor supplied subject tags were not of significant uniqueness or quantity to substantially influence the existing taxonomy. Finally, the publicity of the crowdsourcing feature allowed other institutions to contribute to the project and add rare material. Originality/value – This paper offers a model for utilizing crowdsourcing to entice a sophisticated user group to help build a bibliographic database.
