  • Relationship between Authors’ Structural Position in the
           Collaboration Network and Research Productivity: Case of Indian Earth
    • 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.

  • Extracting bibliographical data for PDF documents with HMM and external
    • Authors: Wen-Feng Hsiao et al
      Abstract: Program, Volume 48, Issue 3, Page 293-313, July 2014. Purpose – The purpose of this paper is to propose an automatic metadata extraction and retrieval system to extract bibliographical information from digital academic documents in portable document formats (PDFs). Design/methodology/approach – The authors use PDFBox to extract text and font size information, a rule-based method to identify titles, and an Hidden Markov Model (HMM) to extract the titles and authors. Finally, the extracted titles and authors (possibly incorrect or incomplete) are sent as query strings to digital libraries (e.g. ACM, IEEE, CiteSeerX, SDOS, and Google Scholar) to retrieve the rest of metadata. Findings – Four experiments are conducted to examine the feasibility of the proposed system. The first experiment compares two different HMM models: multi-state model and one state model (the proposed model). The result shows that one state model can have a comparable performance with multi-state model, but is more suitable to deal with real-world unknown states. The second experiment shows that our proposed model (without the aid of online query) can achieve as good performance as other researcher's model on Cora paper header dataset. In the third experiment the paper examines the performance of our system on a small dataset of 43 real PDF research papers. The result shows that our proposed system (with online query) can perform pretty well on bibliographical data extraction and even outperform the free citation management tool Zotero 3.0. Finally, the paper conducts the fourth experiment with a larger dataset of 103 papers to compare our system with Zotero 4.0. The result shows that our system significantly outperforms Zotero 4.0. The feasibility of the proposed model is thus justified. Research limitations/implications – For academic implication, the system is unique in two folds: first, the system only uses Cora header set for HMM training, without using other tagged datasets or gazetteers resources, which means the system is light and scalable. Second, the system is workable and can be applied to extracting metadata of real-world PDF files. The extracted bibliographical data can then be imported into citation software such as endnote or refworks to increase researchers’ productivity. Practical implications – For practical implication, the system can outperform the existing tool, Zotero v4.0. This provides practitioners good chances to develop similar products in real applications; though it might require some knowledge about HMM implementation. Originality/value – The HMM implementation is not novel. What is innovative is that it actually combines two HMM models. The main model is adapted from Freitag and Mccallum (1999) and the authors add word features of the Nymble HMM (Bikel et al, 1997) to it. The system is workable even without manually tagging the datasets before training the model (the authors just use cora dataset to train and test on real-world PDF papers), as this is significantly different from what other works have done so far. The experimental results have shown sufficient evidence about the feasibility of our proposed method in this aspect.

  • Use of online resources at Jawaharlal Nehru University: a quantitative
    • Authors: Manorama Tripathi et al
      Abstract: Program, Volume 48, Issue 3, Page 272-292, July 2014. Purpose – The main purpose of this paper is to describe the use of e-resources at Jawaharlal Nehru University (JNU), those are being offered through the University Grant Commission – Information and Library Network (UGC-INFONET) consortium. Statistical techniques are applied on usage reports generated by e-resources vendors/publishers to understand trend and seasonality in usages of e-resources in academic libraries. The researchers evaluated gain in popularity of e-resources and drew a comparison in use of various databases of e-resources in terms of volume of downloads over a period of three years. The study would help in designing an instrument to evaluate utilization of e-resources. The cross comparison of databases helps in identifying e-resources, which have been optimally used. Design/methodology/approach – The present study used quantitative approach to express utilization of e-resources in terms of number of downloads of full text research papers from Project Muse, Cambridge University Press, Oxford University Press, Springer Links, Taylor and Francis and JSTOR databases, accessible through the UGC-INFONET consortium. The investigation is based on secondary data of usage statistics made available by the UGC-INFONET consortium. The descriptive statistics techniques have been used in the initial phase of the investigation to understand trend in utilization of e-resources and examine robustness of various statistical tests to identify most appropriate tests for the latter phase of the investigation. The robustness analysis has been recommended for graphical and non-parametric tests for advanced investigation, in the latter phase of the study. The with-in cohort analysis techniques investigates numbers of monthly downloads from each database for a period of three years, i.e. 2008-2010 to explain seasonality in volume of downloads of e-resources. Findings – e-Resources have been gaining popularity gradually in academic libraries; this trend is in tune with gaining of popularity of web-based intellectual resources in other sectors. The study established need of library consortium for sharing resources and subscription fee. The investigation proves significant association between numbers of downloads of e-resources from different databases in the same period; thus gain in popularity of one database encourages readers to explore other databases. The study indicates seasonality effect in the usages of e-resources in academic libraries. This seasonality effect is contemporary to the academic calendar. There are large numbers of downloads just before the examinations, which are held twice in a year and negligible number of downloads during and around long summer study breaks. Thus, the bandwidth rendered to the university is not consistently used during the academic session. The coverage of databases in terms of disciplines and numbers of journals varies to great extent. There is overlapping in the coverage of databases. The strength of students and their demands for scholarly works also vary across disciplines, thus cross comparison of numbers of downloads from databases has little meaning until impact of these three parameters are not controlled in the investigation of utilization of e-resources. Originality/value – The literature shows that no study has been carried out for the use of e-resources by researchers of JNU.

  • A case study for understanding the nature of redundant entities in
           bibliographic digital libraries
    • Authors: Byung-Won On et al
      Abstract: Program, Volume 48, Issue 3, Page 246-271, July 2014. Purpose – The purpose of this paper is to collect and understand the nature of real cases of author name variants that have often appeared in bibliographic digital libraries (DLs) as a case study of the name authority control problem in DLs. Design/methodology/approach – To find a sample of name variants across DLs (e.g. DBLP and ACM) and in a single DL (e.g. ACM), the approach is based on two bipartite matching algorithms: Maximum Weighted Bipartite Matching and Maximum Cardinality Bipartite Matching. Findings – First, the authors validated the effectiveness and efficiency of the bipartite matching algorithms. The authors also studied the nature of real cases of author name variants that had been found across DLs (e.g. ACM, CiteSeer and DBLP) and in a single DL. Originality/value – To the best of the authors knowledge, there is less research effort to understand the nature of author name variants shown in DLs. A thorough analysis can help focus research effort on real problems that arise when the authors perform duplicate detection methods.

  • The impact of Facebook on libraries and librarians: a review of the
    • Authors: Evgenia Vassilakaki et al
      Abstract: Program, Volume 48, Issue 3, Page 226-245, July 2014. Purpose – Social networking sites are becoming more and more popular triggering an increase in published research and impacting different aspects of daily life. One such aspect concerns libraries and librarians and the way they have adopted social networking sites. The purpose of this paper is to present a selective review on libraries’ adoption and use of a specific social networking site such as Facebook in order to promote their services. Design/methodology/approach – The method of selective review is employed to identify, document and present the relevant literature in a structured and annotated way. More specifically, all types of documents published between 2006 and 2012 are considered. In addition, the papers are assigned based on their expressed aim/s to emerged themes and sub-themes. Findings – It was found that the main body of the reported literature focused on reporting experiences, problems and lessons learned from building a presence on Facebook. A few studies aimed to explore users’ and librarians’ perspectives towards social networking sites whereas there is a strong need for specific guidelines to assist libraries and librarians in adopting Facebook. Research limitations/implications – This systematic literature review consists of articles published between 2006 and 2012. Originality/value – This paper contributes to identifying, collecting and presenting research regarding the use of Facebook in the field of library science. In addition, it identifies and summarises the main problems and challenges libraries and librarians are faced with when employing Facebook.
