  • Towards an Evaluation of Semantic Searching in Digital Repositories: A
           DSpace Case-Study
    • Authors: Georgia Solomou et al
      Abstract: Program, Volume 49, Issue 1, February 2015. Purpose Successful learning infrastructures and repositories often depend on well-organized content collections for effective dissemination, maintenance and preservation of resources. By combining semantic descriptions already lying or implicit within their descriptive metadata, reasoning-based or semantic searching of these collections can be enabled and produce novel possibilities for content browsing and retrieval. The specifics and necessities of such an approach however make it hard to assess and measure its effectiveness Design/methodology/approach Therefore in this paper we introduce a concrete methodology towards a pragmatic evaluation of semantic searching in such scenarios, which is exemplified through the Semantic Search plugin we have developed for the popular DSpace repository system. Findings Our results reveal that this approach can be appealing to expert as well as novice users alike, improve the effectiveness of content discovery and enable new retrieval possibilities in comparison to traditional, keyword-based search. Originality/value This paper presents applied research efforts to employ semantic searching techniques on digital repositories and to construct a novel methodology for evaluating the outcomes against various perspectives. Although this is original in itself, value lies also within the concrete and measurable results presented, accompanied by an analysis, that would be helpful to assess similar (i.e. semantic query answering and searching) techniques in the particular scenario of digital repositories and libraries and to evaluate corresponding investments. To our knowledge there has been hardly any other evaluation effort in the literature for this particular case; that is, to assess the merit and usage of advanced semantic technologies in digital repositories.

  • An Investigation Into The Perceptions Of Academic Librarians And Students
           Towards Next-Generation Opacs And Their Features
    • Authors: Hollie M. Osborne et al
      Abstract: Program, Volume 49, Issue 1, February 2015. Purpose This article seeks to determine whether features of next-generation OPAC interfaces are useful and intuitive to users who have different levels of searching ability. In addition, it investigates whether there is a difference between librarians’ and students’ preferences for specific features. Design/methodology/approach The research is based on 18 semi-structured interviews conducted in July 2012 with three groups of library users from The University Of Sheffield (TUOS): librarians; Master of Arts Librarianship students; and a group of other post-graduate students. Findings Overall, this study suggests that while the next-generation catalogue interfaces and features are useful, they are not as “intuitive” as some previous studies have claimed. Interviewees appeared to prefer the searching and browsing options over the Web 2.0 features. Both librarians and students have similar opinions regarding the usefulness of next-generation OPAC features, but preferences are complex. Research limitations/implications The study is based on one institution, and the disciplinary background of the postgraduate students was limited. Practical implications Promoting next generation OPACs and explaining their features to users is essential. Originality/value The paper adds to our understanding of users’ preferences in relation to next-generation OPACs, locating the findings of the current findings firmly in the context of previous literature.

  • Factors Affecting the Satisfaction of an Online Community for Archive
           Management in Taiwan
    • Authors: Fang-Ming HSU et al
      Abstract: Program, Volume 49, Issue 1, February 2015. Purpose The purpose of this study is to investigate the relationship between the richness of information and the satisfaction of participants in an online community regarding archive management in Taiwan. Design/methodology/approach An investigation was deployed to attendants in 20 training courses created by the National Archives Administration (NAA) in Taiwan for records staff on the topic of digital preservation. The responses were collected from respondents who were participating in an online community for archive management. Through structural equation modeling method, this study examined the effects of channel richness, information transparency and accessibility of archive to brand image and trust and then continued to the satisfaction of professional participants to archive management in an online community. Findings Appropriate disclosure of information regarding archiving can effectively improve the satisfaction of participants in the online community to archive. Channel richness of communication, information transparency and accessibility of archive significantly affect the brand image of archive and the trust of participants to archivists and finally affect the satisfaction of participants in the online community toward archive management. Practical implications The larger the amount of information exchanged, the more the trust among participants and the better brand image of the archives. The more trust and brand image exists among participants, the more satisfaction they will obtain from archive management. Originality/value The results can provide a strategic direction for managers of the national archive and the online community in government agencies to allocate resources for enhancing the information richness and the image of archive as well as achieving the satisfaction of participants in the professional community.

  • A Feature Selection Approach for Automatic E-book Classification Based on
           Discourse Segmentation
    • Authors: Jiunn-Liang Guo et al
      Abstract: Program, Volume 49, Issue 1, February 2015. Purpose The aim of this paper is to develop a novel feature selection approach for automatic text classification of large digital documents – E-books of online library system. The main idea mainly aims on automatically identifying the discourse features in order to improving the feature selection process rather than focusing on the size of the corpus. Design/methodology/approach The proposed framework intends to automatically identify the discourse segments within e-books and capture proper discourse subtopics that are cohesively expressed in discourse segments and treating these subtopics as informative and prominent features. The selected set of features is then used to train and perform the e-book classification task based on the SVM technique. Findings The evaluation of the proposed framework shows that identifying discourse segments and capturing subtopic features leads to better performance, in comparison with two conventional feature selection techniques: TFIDF and MI. It also demonstrates that discourse features play important roles among textual features, especially for large documents such as e-books. Research limitations/implications Automatically extracted subtopic features cannot be directly entered into FS process but requires control of the threshold. Practical implications The proposed technique has demonstrated the promised application of using discourse analysis to enhance the classification of large digital documents – e-books as against to conventional techniques. Originality/value A new FS technique is proposed which can inspect the narrative structure of large documents and it is new to the text classification domain. The other contribution is that it inspires the consideration of discourse information in future text analysis, by providing more evidences through evaluation of the results. The proposed system can be integrated into other library management systems.

  • Enhancing the management of unstructured data in e-learning systems using
           MongoDB
    • Authors: Milorad Pantelija Stević et al
      Abstract: Program, Volume 49, Issue 1, February 2015. Purpose Current e-learning platforms are based on relational database management systems and are well suited for handling structured data. However, it is expected from e-learning solutions to efficiently handle unstructured data as well. The purpose of this paper is to show an alternative to current solutions for unstructured data management. Design/methodology/approach Current repository-based solution for file management was compared to MongoDB architecture according to their functionalities and characteristics. This included several categories: data integrity, hardware acquisition, processing files, availability, handling concurrent users, partition tolerance, disaster recovery, backup policies and scalability. Findings This paper shows that it is possible to improve e-learning platform capabilities by implementing a hybrid database architecture that incorporates relational database management system for handling structured data and MongoDB database system for handling unstructured data. Research limitations/implications The study shows an acceptable adoption of MongoDB inside a service oriented architecture (SOA) for enhancing e-learning solutions. Practical implications This research enables an efficient file handling not only for e-learning systems, but also for any system where file handling is needed. Originality/value It is expected that future single/joint e-learning initiatives will need to manage huge amount of files and they will require effective file handling solution. The new architecture solution for file handling is offered in this paper: it is different from current solutions because it is less expensive, more efficient, more flexible and requires less administrative and development effort for building and maintaining.

  • Establishing of a Slovenian open access infrastructure: a technical point
           of view
    • Authors: Milan Ojsteršek et al
      Abstract: Program, Volume 48, Issue 4, Page 394-412, August 2014. Purpose – The purpose of this paper is to present a technical perspective when implementing the Slovenian open access infrastructure that consists of four institutional repositories (IRs) and a national portal (NP) that aggregates content from the repositories in order to provide a common search engine, recommendations of similar documents, and similar text detection. Design/methodology/approach – During the project, the necessary legal background and processes for mandatory submissions of final study works, research publications and research data were established, as well as processes for data exchange between the IRs and the NP, and processes for similar text detection. Findings – The consortium consisted of four Slovenian universities that significantly differ in size, organisation, and workflows. It was anticipated that exactly the same legal background and software would be used for the four repositories. It turned out that complete unification was impossible due to the differences. Practical implications – The national open access infrastructure will improve the visibility of Slovenian research organisations. It supports the compliance with the funders’ open access mandates. The established infrastructure enables the depositing and archiving of approximately 80 percent of the peer-reviewed scientific publications that are annually published by Slovenian researchers. At the same time, the majority of final study works from Slovenian higher education institutions are available in full-text format. Originality/value – This paper describes a technical perspective for setting up a national open access infrastructure, which has not been described in the literature previously.

  • Relationship between Authors’ Structural Position in the
           Collaboration Network and Research Productivity: Case of Indian Earth
           Scientists
    • Authors: Sameer Kumar et al
      Abstract: Program, Volume 48, Issue 4, August 2014. Purpose The focus of this paper was to compute and analyze the topological properties of co-authorship network formed between earth scientists in India. As a case study, we evaluate bibliographic data of authors who have contributed research articles in the Journal of the Geological Society of India (JGSI), a premier Earth Science journal in India. Design/methodology/approach Research articles totaling 3903 records from 1970 to 2011 were harvested from the ISI Web of Science SCI database and analyzed using Social Network Analysis (SNA). Findings The author productivity in terms of number of papers published followed Lotka's law with = 2.1027. A dense giant component was detected that spanned 73% of the network with a density of 0.0017 and clustering coefficient of 0.631, suggesting high level of knowledge diffusion and a rapid flow of information and creativity in this network. Local metrics were calculated using degree, betweenness and closeness centralities. A strong correlation was seen between degree and author productivity (number of works) and betweenness centrality and author productivity, suggesting that author’s number of connections and controlling ‘in-between’ position in the network may be providing the authors’ with the knowledge and resources to be more productive. Originality/value The impact of human actions on the earth systems is a hot topic of research in India. This is one of the first works that investigates co-authorship networks of Indian earth science researchers.

  • Analysis of Customer Churn Behavior in Digital Libraries
    • Authors: Yuangen Lai et al
      Abstract: Program, Volume 48, Issue 4, August 2014. Purpose To discuss issues related to customer churn behavior in digital libraries and demonstrate the successful application of Survival Analysis for understanding customer churn status and relationship duration distribution between customers and libraries. Design/methodology/approach The study applies non-parametric methods of Survival Analysis to analyze churn behaviors of 8054 customers from a famous Chinese digital library, and a cluster method to make customer segmentation according to customer behavioral features. Findings The customer churn rate of the given library is very high, so as to the churn hazard in early three months after customer’s registration on the website of the library. There is clear difference in both customer survival time and churn hazard among customer groups. It is necessary to strengthen customer churn analysis and customer relationship management for digital libraries. Research limitations/implications The studied samples are mainly based on customers from one digital library and some hypotheses have not been strictly proven due to the absence of relevant empirical researches. Practical implications This study provides a reasonable basis for decision-making about customer relationship management in digital libraries. Originality/value Most previous researches about information behavior concentrate on information seeking behavior in digital libraries, seldom discuss customer switching behavior. The paper discusses issues related to customer churn analysis and illustrates the adaptation of Survival Analysis to understand customer churn status and relationship duration distribution in digital libraries.

  • E-ViVa, the national Hellenic fulltext database on Librarianship and
           Information Science.
    • Authors: Filippos Tsimpoglou et al
      Abstract: Program, Volume 48, Issue 4, August 2014. Purpose The paper presents E-ViVa (Ellinike Vivliothikonomike Vase), the national Hellenic fulltext database on Librarianship and Information Science, developed by the Library of the University of Cyprus. The objectives of E-ViVa are to identify, locate, gather, organize, index, digitize, preserve and promote the results of the research conducted in Greece and Cyprus in the scien-tific fields of Archival, Library and Information Sciences Design/methodology/approach The paper provides data concerning the volume, the coverage, the inclusion criteria, the content, the format and the platform of the database, as well as the steps that have been followed for the development. The legal framework related with the copyright issues that are raised are also discussed. Findings A comparison is attempted between the coverage of E-ViVa and the relative records included in five subject related databases: eLIS, LISA, LISTA, ISI-SSCI and SCOPUS. Finally the future plans for the project are presented. Research limitations/implications Future plans concerning E-ViVa are based a) on the com-pleteness of the database, b) the linguistic expoitation of the terms used through time and c) check of Lotka’s law application concerning authors. Practical implications As the vast majority of the records and fulltext are not provided by any other organised database, E-VIVA emerges as a "must search first" for any future author of scientific paper concerning the situation on librarianship research in Greece and Cyprus. The case of E-ViVa and the methodology that was followed can be used as a pattern for developing national databases on LIS or other fields. Originality/value E-ViVa is the only fulltext database on Librarianship and Information Science, which concentrates the related publications produced in or related to Greece and Cyprus.

  • The D-NET Software Toolkit: A Framework for the Realization, Maintenance,
           and Operation of Aggregative Infrastructures
    • Authors: Paolo Manghi et al
      Abstract: Program, Volume 48, Issue 4, August 2014. Purpose This paper presents the architectural principles and the services of the D-NET Software Toolkit. D-NET is a framework where designers and developers find the tools for constructing and operating aggregative infrastructures (systems for aggregating data sources with heterogeneous data models and technologies) in a cost-effective way. Designers and developers can select from a variety of D-NET data management services, can configure them to handle data according to given data models, and can construct autonomic workflows to obtain personalized aggregative infrastructures. Design/methodology/approach The paper provides a definition of aggregative infrastructures, sketching architecture and components, as inspired by real-case examples. It then describes the limits of current solutions, which find their lacks in the realization and maintenance costs of such complex software. Finally, it proposes D-NET as an optimal solution for designers and developers willing to realize aggregative infrastructures. The D-NET architecture and services are presented, drawing a parallel with the ones of aggregative infrastructures. Finally, real-cases of D-NET are presented, to show-case the statement above. Findings The D-NET software toolkit is a general-purpose service-oriented framework where designers can construct customised, robust, scalable, autonomic aggregative infrastructures in a cost-effective way. D-NET is today adopted by several EC projects, national consortia and communities to create customised infrastructures under diverse application domains, and other organisations are enquiring for or are experimenting its adoption. Its customisability and extendibility make D-NET a suitable candidate for creating aggregative infrastructures mediating between different scientific domains and therefore supporting multi-disciplinary research. Originality/value D-NET is the first general-purpose framework of this kind. Other solutions are available in the literature but focus on specific use-cases and therefore suffer from the limited re-use in different contexts. Due to its maturity, D-NET can also be used by third-party organizations, not necessarily involved in the software design and maintenance.
