  • Construction of personal knowledge maps for a peer-to-peer
           information-sharing environment
    • Pages: 394 - 413
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 394-413, June 2018.
      Purpose Browsing knowledge documents in a peer-to-peer (P2P) environment is difficult because knowledge documents in such an environment are large in quantity and distributed over different peers who organize the documents according to their own views. This paper aims to propose a method for constructing a personal knowledge map for a peer to facilitate knowledge browsing and alleviate information overload in P2P environments. Design/methodology/approach The research presents a method for constructing a personal knowledge map. The method adopts an ontology-concept-tree-based classification algorithm to recognize a peer’s personal knowledge structure and construct a personal knowledge map, and uses a self-organizing map algorithm to cluster and visualize the knowledge documents. The correctness of the created knowledge map is evaluated with a collection of abstracts of academic papers. Findings The method for constructing a personal knowledge map is the main finding of this research. The evaluation shows that the created knowledge map is good in quality. Research limitations/implications The proposed method provides a way for P2P platforms to understand their users’ knowledge background, as well as to improve the P2P platform environment. However, the proposed method will not help a peer when he has nothing in his individual knowledge document repository (i.e. the “cold start” problem). The method also requires a relatively good ontology base for a P2P document sharing system to use the method effectively. Originality/value It is novel that the proposed method organizes the knowledge documents related to a peer’s knowledge background into a personal knowledge map. Moreover, the created knowledge map combines the advantages of a hierarchical display and a map display. It has values for a distributed P2P environment to facilitate users’ knowledge browsing and to alleviate information overload.

  • Geographical visualization of research collaborations of library science
           in China
    • Pages: 414 - 429
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 414-429, June 2018.
      Purpose The purpose of this paper is to visualize the collaboration network among regions in library science (LS) in China. Using various methods and tools of social network analysis and geographical visualization, results were obtained, showing the structure and patterns of research collaborations in topological and geographical views, as well as the geographical distributions of contribution. Design/methodology/approach The sample includes all studies published in the top journal in library science in China from 2006 to 2015. First, co-occurrence data representing collaborations among regions was extracted from author affiliations. Second, the topological network of collaboration was generated by applying social network analysis tools and descriptive statistics, network indicators of the collaboration network and research communities were calculated. Third, the topological network was projected into a geographical map with corresponding coordinates and distances using geographical tools. Finally, the topological network maps and the geographical maps were produced for visualization. Findings The levels of contribution are very unbalanced between regions, and overall research collaboration is low. Beijing, Hubei and several other areas are central and significant regions in China; other regions are mostly connected with central ones through direct collaborations. Research collaborations in LS research in China are mostly distributed in the east and south of China, being centralized in the “Beijing–Hubei–Shanghai” triangle zone, as well as within the triangle’s extending zones. Finally, there are three distinct research communities that connect closely within themselves and loosely between them. The Beijing community is relatively centralized in geography, while other communities are scattered. Originality/value This study applied various methods and tools of social network analysis and geographical mapping analysis to reveal the collaboration structure and patterns among regions in LS research in China. Visualized maps in topological and geographical views help shed new light on research efforts.

  • Domain-specific readability measures to improve information retrieval in
           the Persian language
    • Pages: 430 - 444
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 430-444, June 2018.
      Purpose The degree to which a text is considered readable depends on the capability of the reader. This assumption puts different information retrieval systems at the risk of retrieving unreadable or hard-to-be-read yet relevant documents for their users. This paper aims to examine the potential use of concept-based readability measures along with classic measures for re-ranking search results in information retrieval systems, specifically in the Persian language. Design/methodology/approach Flesch–Dayani as a classic readability measure along with document scope (DS) and document cohesion (DC) as domain-specific measures have been applied for scoring the retrieved documents from Google (181 documents) and the RICeST database (215 documents) in the field of computer science and information technology (IT). The re-ranked result has been compared with the ranking of potential users regarding their readability. Findings The results show that there is a difference among subcategories of the computer science and IT field according to their readability and understandability. This study also shows that it is possible to develop a hybrid score based on DS and DC measures and, among all four applied scores in re-ranking the documents, the re-ranked list of documents based on the DSDC score shows correlation with re-ranking of the participants in both groups. Practical implications The findings of this study would foster a new option in re-ranking search results based on their difficulty for experts and non-experts in different fields. Originality/value The findings and the two-mode re-ranking model proposed in this paper along with its primary focus on domain-specific readability in the Persian language would help Web search engines and online databases in further refining the search results in pursuit of retrieving useful texts for users with differing expertise.

  • Exploring the context of visual information seeking
    • Pages: 445 - 456
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 445-456, June 2018.
      Purpose Information seeking is an interactive behaviour of the end users with information systems, which occurs in a real environment known as context. Context affects information-seeking behaviour in many different ways. The purpose of this paper is to investigate the factors that potentially constitute the context of visual information seeking. Design/methodology/approach The authors used a Straussian version of grounded theory, a qualitative approach, to conduct the study. Using a purposive sampling method, 28 subjects participated in the study. The data were analysed using open, axial and selective coding in MAXQDA software. Findings The contextual factors influencing visual information seeking were classified into seven categories, including: “user characteristics”, “general search features”, “visual search features”, “display of results”, “accessibility of results”, “task type” and “environmental factors”. Practical/implications This study contributes to a better understanding of how people conduct searches in and interact with visual search interfaces. Results have important implications for the designers of information retrieval systems. Originality/value This paper is among the pioneer studies investigating contextual factors influencing information seeking in visual information retrieval systems.

           country‚Äôs perspective
    • Pages: 457 - 470
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 457-470, June 2018.
      Purpose The purpose of this study is to identify barriers that are hindering digitization initiatives in university libraries of Pakistan. Design/methodology/approach The study opted a mixed-methods research design based on quantitative (QUAN) and qualitative (QUAL) strands by using a survey research method. The subjects of the study were central libraries of the universities (both public and private sector) of Pakistan. A self-administered structured questionnaire was used for QUAN data collection in the QUAN strand. In the QUAL phase, in-depth interviews of purposely selected 25 library experts from different parts of the country were conducted. Findings Meta-inferences were drawn from the findings of both QUAN and QUAL strands. Both of the research designs provided the requisite data to answer research questions of the study. The finding revealed the barriers which were hindering the digitization activities in university libraries of Pakistan. Originality/value The findings of the study are helpful for funding bodies, university libraries and university administration. The findings are also helpful for other developing countries with similar economic and/or social landscapes.

  • Improving the discoverability of PhD student work through a CRIS system
    • Pages: 471 - 486
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 471-486, June 2018.
      Purpose Dissertations from the University of Novi Sad (UNS) are integrated with the research information system called the current research information system (CRIS) UNS. This paper aims to present a proposal for an extension of this system to enable the storage of student papers as prescribed by PhD study exam obligations. The proposed extension enables preservation and improves discoverability of scientific and technical works produced by students during their PhD studies. Design/methodology/approach An analysis of examination modes in accredited PhD study programs has been conducted. It was noted that students in examination modes verify the obtained results in the form of scientific and technical work. The main idea of this paper is to enable the preservation of those student results and to implement electronic services for retrieving those results by current and future PhD students to empower the development of science. Findings The proposal includes an extension of the CRIS UNS to store and publish student papers as prescribed as a PhD study exam obligation; an extension of the CERIF data model to enable storing of student papers; cataloguing student papers in the MARC 21 format; and a way to represent student papers in the Dublin Core format. Practical implications This paper can be a starting point for initiatives for the creation of institutional, regional, national and international Web portals for searching and browsing papers by PhD students. Social implications This system offers the improvement of cooperation between PhD students from different institutions and countries. Originality/value The paper presents an extension of institutional, national and international current research information system (CRIS) systems which will enable the preservation and improve discoverability of student papers produced during PhD studies. The proposed extension has been verified by its implementation within the CRIS UNS system, which also supports monitoring of the scientific competencies of students based on an automatic evaluation of published scientific results.

  • Usability testing for an open-source integrated library system
    • Pages: 487 - 503
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 487-503, June 2018.
      Purpose The aim of this paper is to empirically examine the usability of the Koha OPAC from a user perspective. Design/methodology/approach A series of usability tests with Koha were carried out at a private university in Bangladesh. Both experienced and novice users participated in these tests. Experienced users participated only once, whereas novices took part in three successive sessions. At first, novices’ initial performance was recorded. Then, they performed the same tasks after a short training tutorial. Novices again participated in the retention experiment with the same tasks after four weeks. A set of seven tasks was given to the users to see their performance in terms of time taken, number of errors made and success scores. Performance data were captured through a computer screen recording software, and satisfaction scores were obtained using a modified version of Questionnaire on User Interface Satisfaction (QUIS). Comparisons of performance and satisfaction with Koha OPAC were made between experienced users and novices’ initial, learning and retention experiments and amongst novices’ three test sessions. Findings The results showed significant performance difference between experienced and novices’ initial session. Novices could easily pick up the functionality of Koha OPAC when a brief training was provided. The comparative analysis of performance between experienced users and novices’ learning showed no significant difference between these sessions. There was a significant difference between experienced and novices’ retention in terms of success scores. The comparison amongst novices’ initial, learning and retention sessions showed significant performance differences in time taken and errors made. The QUIS results also showed significant differences in subjective satisfaction for several items between experienced users and naïve sessions, and for one item amongst novices’ three experiments. Originality/value This is a pioneering study of the task-based usability of Koha OPAC. The findings from this study will encourage researchers to empirically examine the usability of other open-source ILSs, which might result in improved user performance and satisfaction with these systems.

  • Institutional repositories: a bibliometric study of the social sciences
           citation index (SSCI)
    • Pages: 504 - 517
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 504-517, June 2018.
      Purpose This paper aims to provide a bibliometric study of journal articles related to institutional repositories in the Social Sciences Citation Index (SSCI) between January 1993 and August 2017. This study will provide researchers with a foundation for further research. Design/methodology/approach In this study, articles published were analyzed; titles were searched using the term “institutional repositories.” The data were evaluated in response to four research questions on the following topics: publication trends, prolific authors, core journals and times cited. Findings The results indicate that 124 articles on institutional repositories were authored by 223 individuals. These articles were cited 722 times in 37 journals, and the h-index provided by the Web of Science was 14. Research limitations/implications This study only investigated articles titled with institutional repositories in the SSCI. Other items were not included. Practical implications This study shows that the implementation of institutional repositories has been limited to library and information science. If they can be used broadly in different disciplines, a better outcome can be expected. Social implications Based on the findings, the growth of institutional repositories as an academic subject is likely to continue. If such discussions can be conducted in other disciplines, institutional repositories may be able to provide a more promising outcome to academia. Originality/value This paper is valuable for researchers who wish to examine the trends of institutional repositories in the SSCI and seek possible areas for further research.

  • Factors affecting student use of Web-based services
    • Pages: 518 - 534
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 518-534, June 2018.
      Purpose The delivery of information services in higher education is increasingly relying on Web-based systems. The low adoption and underutilization of information systems have been major problems for developing countries such as Pakistan in terms of realizing their full benefits. This study aims to investigate factors affecting student use of Allama Iqbal Open University’s (AIOU) Web-based services by using the Unified Theory of Acceptance and Use of Technology (UTAUT) from the perspective of Pakistani distance education. Design/methodology/approach This study has adopted quantitative research design with the UTAUT model as a theoretical framework. A self-completion structured questionnaire-based survey has been administered to 388 master’s level students, selected through systematic sampling from the target population. The response rate was 82 per cent (318). All statistical tests have been performed using IBM SPSS (version 20.0) and Process macro for SPSS. Findings Findings of the model’s hypotheses reveal that performance expectancy, effort expectancy and social influence are significant predictors of student behavioural intention to use AIOU Web-based services, whereas actual student use is dependent on facilitating conditions and student behavioural intention to use. The impact of moderating variables with respect to age, gender and experience did not influence the actual use of the Web services. However, the research model significantly measured (62.1 per cent) the actual use of AIOU Web-based services by the students. Research limitations/implications This study is delimited to the UTAUT model to investigate the phenomena. Besides this, the context of the study is the voluntary instead of mandatory usage of Web services. A study conducted in mandatory settings, in which students are bound to use Web services, may have different results. Originality/value This is the first attempt to apply the UTAUT model to investigate the factors affecting student use of Web-based services from the perspective of distance education and the findings prove strong support for the model.

  • The smart library project
    • Pages: 535 - 549
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 535-549, June 2018.
      Purpose This paper aims to analyse the phenomenon of smart libraries, which began in the 2000s, alongside the development of computer technology, digital storage the internet and human–computer interactions. The smart library is a system of library and information services developed to support research and training activity. This paper describes the need to introduce innovative library and information services at universities through users’ personal accounts. Design/methodology/approach An analysis of more than 200 publications mainly written by foreign scientists was conducted, given the dearth of Russian literature on the smart library and its services. The analysis revealed that in Western countries, the term smart library represents a wide range of meanings – from the understanding that it is a typical type of networking to assumptions about the total services provided by libraries in an urban environment. Findings The paper presents a review of both classical library services and those that are focused on the needs of modern education and science. Research limitations/implications The research results may be the best limited to university libraries. Practical implications The research results have practical use in the Library and Publishing Complex of the Siberian Federal University. Consequently, a new library information environment has been developed and integrated into the university’s information space. Social implications The research results have social use in Siberian Federal University. The personal account can be regarded as a functioning system of interaction and information exchange among the automated systems of the Library and Publishing Complex, automated learning management system and integrated educational environment. Originality/value This paper presents a certain set of technical solutions and some services available through personal accounts.

  • Semi-automatic extraction of multiword terms from domain-specific corpora
    • Pages: 550 - 567
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 550-567, June 2018.
      Purpose A hybrid approach is presented, which combines linguistic and statistical information to semi-automatically extract multiword term candidates from texts. Design/methodology/approach The method is designed to be domain and language independent, focusing on languages with rich morphology. Here, it is used for extracting multiword terms from texts in Serbian, belonging to the agricultural engineering domain, as a use case. Predefined syntactic structures were used for multiword terms. For each structure, a finite state transducer was developed, which recognizes text sequences having that structure and outputs the sequence in a normalized form, so that different inflectional forms of the same multiword term can be counted properly. Term candidates were further filtered by their frequencies and evaluated by two domain experts. Findings By using language resources, such as electronic dictionaries and grammars, 928 multiword terms were extracted out of 1,523 multiword terms that were recognized as candidates from a corpus having 42,260 different simple word forms; 870 of these were new, not already contained in the existing electronic dictionary of compounds for Serbian, and they were used to enrich the dictionary. Originality/value The paper presents methodology that can significantly contribute to the development of terminology lexicons in different areas. In this particular use case, some important agricultural engineering concepts were extracted from the text, but this approach could be used for other domains and languages as well.

  • Can I have more of these please'
    • Pages: 568 - 587
      Abstract: The Electronic Library, Volume 36, Issue 3, Page 568-587, June 2018.
      Purpose During the literature review phase, the task of finding similar research papers can be a difficult proposition for researchers due to the procedural complexity of the task. Current systems and approaches help in finding similar papers for a given paper, even though researchers tend to additionally search using a set of papers. This paper aims to focus on conceptualizing and developing recommendation techniques for key literature review and manuscript preparatory tasks that are interconnected. In this paper, the user evaluation results of the task where seed basket-based discovery of papers is performed are presented. Design/methodology/approach A user evaluation study was conducted on a corpus of papers extracted from the ACM Digital Library. Participants in the study included 121 researchers who had experience in authoring research papers. Participants, split into students and staff groups, had to select one of the provided 43 topics and run the tasks offered by the developed assistive system. A questionnaire was provided at the end of each task for evaluating the task performance. Findings The results show that the student group evaluated the task more favourably than the staff group, even though the difference was statistically significant for only 5 of the 16 measures. The measures topical relevance, interdisciplinarity, familiarity and usefulness were found to be significant predictors for user satisfaction in this task. A majority of the participants, who explicitly stated the need for assistance in finding similar papers, were satisfied with the recommended papers in the study. Originality/value The current research helps in bridging the gap between novices and experts in terms of literature review skills. The hybrid recommendation technique evaluated in this study highlights the effectiveness of combining the results of different approaches in finding similar papers.
