- Abstract
- On a scientific concept hierarchy, a parent concept may have a few attributes, each of which has multiple values being a group of child concepts. We call these attributes facets: classification has a few facets such as application (e.g., face recognition), model (e.g., svm, knn), and metric (e.g., precision). In this work, we aim at building faceted concept hierarchies from scientific literature. Hierarchy construction methods heavily rely on hypernym detection, however, the faceted relations are parent-to-child links but the hypernym relation is a multi-hop, i.e., ancestor-to-descendent link with a specific facet "type-of". We use information extraction techniques to find synonyms, sibling concepts, and ancestor-descendent relations from a data science corpus. And we propose a hierarchy growth algorithm to infer the parent-child links from the three types of relationships. It resolves conflicts by maintaining the acyclic structure of a hierarchy.

- Abstract
- To "classify" in Library and Information Sciences (LIS) usually involves an engagement with formally established classification systems, such as the Dewey Decimal Classification. In this research I suggest an alternative path for LIS scholars - one that considers the application of LIS theories about classification to the investigation of everyday life "classification" processes and technologies.

- Abstract
- This article outlines the history of library and information science (LIS), from its roots in library science, information science and documentation. It considers various conceptions or "paradigms" in the field and discusses the topical content of LIS as well as the relationships between LIS and other disciplines. The main argument of the article is that answers to all such questions concerning LIS are related to conceptions of LIS. It is argued that an updated version of social epistemology (SE), which was founded by Egan and Shera in 1952, may in hindsight provide the most fruitful theoretical frame for LIS. SE is related to the domain-analytic approach, which was suggested by Hjørland and Albrechtsen in 1995.

- Abstract
- This article outlines the history of library and information science (LIS), from its roots in library science, information science and documentation. It considers various conceptions or "paradigms" in the field and discusses the topical content of LIS as well as the relationships between LIS and other disciplines. The main argument of the article is that answers to all such questions concerning LIS are related to conceptions of LIS. It is argued that an updated version of social epistemology (SE), which was founded by Egan and Shera in 1952, may in hindsight provide the most fruitful theoretical frame for LIS. SE is related to the domain-analytic approach, which was suggested by Hjørland and Albrechtsen in 1995.

- Abstract
- Classification is the basis of knowledge organization. Ontology, a comparatively new concept used as a tool for knowledge organization, establishes connections between terms and concepts enhancing the scope and usefulness of library classification. Ranganathan had invented the strong theory of the analytico-synthetic method in classification and devised Colon Classification. In this study a domain ontology on library and information science has been developed by implementing Raganathan's faceted approach of classification. The hierarchical relationships among terms have been established primarily keeping conformity with that of Ranganathan's Colon Classification (7th edition). But to accommodate new vocabularies, DDC 23rd edition and UDC Standard edition are consulted. The Protégé ontology editor has been used. The study carefully examines the steps in which the analytico-synthetic method have been followed. Ranganathan's Canon of Characteristics and its relevant Canons have been followed for defining the class-subclass hierarchy. It concludes by identifying the drawbacks as well as the merits faced while developing the ontology. This paper proves the relevance and importance of Ranganathan's philosophy in developing ontology based knowledge organization.

- Abstract
- Data is everywhere - praktisch bei allen wissenschaftlichen, staatlichen, gesellschaftlichen und wirtschaftlichen Aktivitäten entstehen sie. Die Daten werden erzeugt durch Befragungen, mobile und eingebettete Systeme, Sensoren, Beobachtungssysteme, wissenschaftliche Instrumente, Publikationen, Experimente, Simulationen, Auswertungen und Analysen. Bürger, Wissenschaftler, Forschende und Lehrende kommunizieren durch den Austausch von Daten, Software, Veröffentlichungen, Berichte, Simulationen und Visualisierungen. Darüber hinaus führen die zunehmende Nutzung der visuellen Kommunikation für Unterhaltung und zwischenmenschlichen Beziehungen sowie die rasche Zunahme der sozialen Netzwerke zu riesigen Datenmengen. Daten von Observatorien, Experimenten und Umweltüberwachung sowie aus der Genforschung und dem Gesundheitswesen generieren eine Größenordnung von Daten alle zwei Jahre, die weit über das Mooresche Gesetz hinausgeht - und dabei ist noch kein Ende in Sicht. Wissenschaftliche Publikationen sind Datengrundlage für die weitere wissenschaftliche Arbeit und Publikationen.

- Abstract
- Interdisciplinarity has been studied using cognitive connections among individuals in corresponding domains, but rarely from the perspective of academic genealogy. This article utilizes academic genealogy network data from 3,038 PhD dissertations in Library and Information Science (LIS) over a span of 80 years (1930-2009) to describe interdisciplinary changes in the discipline. Aspects of academic pedigree of advisors and committee members are analyzed, such as country, school, and discipline of highest degree, to reveal the interdisciplinary features of LIS. The results demonstrate a strong history of mentors from fields such as education and psychology, a decreasing trend of mentors with LIS degrees, and an increasing trend in mentors receiving degrees in computer science, business, and communication, among other disciplines. This work proposes and explores the use of academic genealogy as an indicator of interdisciplinarity and calls for additional research on the role of doctoral committee composition in a student's subsequent academic career.

- Abstract
- Using the library and information science journals 2003-2012 in Nanjing University's Chinese Social Sciences Citation Index as data sources, the paper reveals the citation structure implied in these journals by applying social network analysis. Results show that, first, journal knowledge transfer activity in library and information science is frequent, and both the level of knowledge and discipline integration as well as the knowledge gap influenced knowledge transfer activity. According to the out-degree and in-degree, journals can be divided into three kinds. Second, based on professional bias and citation frequency, the knowledge transfer network can be divided into four blocks. With the change of discipline capacity and knowledge gap among journals, the "core-periphery" structure of the knowledge transfer network is getting weaker. Finally, regions of the knowledge transfer network evolved from a "weak-weak" subgroup to a "strong-weak" subgroup or a "weak-strong" subgroup, and then move to a "strong-strong" subgroup.

- Abstract
- Normalization of citation scores using reference sets based on Web of Science subject categories (WCs) has become an established ("best") practice in evaluative bibliometrics. For example, the Times Higher Education World University Rankings are, among other things, based on this operationalization. However, WCs were developed decades ago for the purpose of information retrieval and evolved incrementally with the database; the classification is machine-based and partially manually corrected. Using the WC "information science & library science" and the WCs attributed to journals in the field of "science and technology studies," we show that WCs do not provide sufficient analytical clarity to carry bibliometric normalization in evaluation practices because of "indexer effects." Can the compliance with "best practices" be replaced with an ambition to develop "best possible practices"? New research questions can then be envisaged.

- Abstract
- General graph random walk has been successfully applied in multi-document summarization, but it has some limitations to process documents by this way. In this paper, we propose a novel hypergraph based vertex-reinforced random walk framework for multi-document summarization. The framework first exploits the Hierarchical Dirichlet Process (HDP) topic model to learn a word-topic probability distribution in sentences. Then the hypergraph is used to capture both cluster relationship based on the word-topic probability distribution and pairwise similarity among sentences. Finally, a time-variant random walk algorithm for hypergraphs is developed to rank sentences which ensures sentence diversity by vertex-reinforcement in summaries. Experimental results on the public available dataset demonstrate the effectiveness of our framework.

- Abstract
- Purpose - Library and information science (LIS) and the digital humanities are both interested in studying recorded information and often share institutional frameworks. The purpose of this paper is to go beyond outlining these similarities by examining the perceived and real strengths and weaknesses of both disciplines. Design/methodology/approach - Epistemologies and methods of both disciplines are analysed, principally in the light of the growing importance of data-intensive research, taking into consideration that there is a tension about the academic status of these disciplines. Findings - Epistemologies and methods of both disciplines are analysed, principally in the light of the growing importance of data-intensive research, taking into consideration that there is a tension about the academic status of these disciplines. Originality/value - The paper intends to be an add-on to the recent discussions and the evolving body of knowledge about the relationship of these disciplines with the hope of indicating a possible new direction in the development of LIS.

- Abstract
- Journals in the Information Science & Library Science category of Journal Citation Reports (JCR) were compared using both bibliometric and bibliographic features. Data collected covered journal impact factor (JIF), number of issues per year, number of authors per article, longevity, editorial board membership, frequency of publication, number of databases indexing the journal, number of aggregators providing full-text access, country of publication, JCR categories, Dewey decimal classification, and journal statement of scope. Three features significantly correlated with JIF: number of editorial board members and number of JCR categories in which a journal is listed correlated positively; journal longevity correlated negatively with JIF. Coword analysis of journal descriptions provided a proximity clustering of journals, which differed considerably from the clusters based on editorial board membership. Finally, a multiple linear regression model was built to predict the JIF based on all the collected bibliographic features.

- Abstract
- In theory, articles can attract readers on the social reference sharing site Mendeley before they can attract citations, so Mendeley altmetrics could provide early indications of article impact. This article investigates the influence of time on the number of Mendeley readers of an article through a theoretical discussion and an investigation into the relationship between counts of readers of, and citations to, 4 general library and information science (LIS) journals. For this discipline, it takes about 7 years for articles to attract as many Scopus citations as Mendeley readers, and after this the Spearman correlation between readers and citers is stable at about 0.6 for all years. This suggests that Mendeley readership counts may be useful impact indicators for both newer and older articles. The lack of dates for individual Mendeley article readers and an unknown bias toward more recent articles mean that readership data should be normalized individually by year, however, before making any comparisons between articles published in different years.

- Abstract
- Purpose The purpose of this paper is to explore an approach to epistemology which allows a portion of library and information science (LIS) to coherently explain its social and intellectual contributions, and to overcome some of the problems of epistemology that LIS encounters. Design/methodology/approach Literature based conceptual analysis of the problems of epistemology in LIS and the productive approach of Deweyan Pragmatism. Findings LIS' problems with epistemology come from a variety of sources: epistemology itself, the combining of librarianship with information science, and the search for a common grounding of the information professions, their tools and their institutions. No such theoretical foundation is possible, but Deweyan Pragmatism offers a sensible, practical explanation for the historical development and practices of librarianship. Originality/value Pragmatism has been deployed in portions of LIS, but the full implications and the "fit" of Dewey's ideas for librarianship and its epistemology are productive explorations.

- Abstract
- Purpose The purpose of this paper is to re-examine the proposal that Luciano Floridi's philosphy of information (PI) may be an appropriate conceptual foundation for the discipline of library and information science (LIS). Design/methodology/approach A selective literature review and analysis are carried out. Findings It is concluded that LIS is in need of a new conceptual framework, and that PI is appropriate for this purpose. Originality/value Floridi proposed a close relationship between PI and LIS more than a decade ago. Although various authors have addressed the aspects of this relationship since then, this is the first proposal from an LIS perspective that PI be adopted as a basis for LIS.

- Abstract
- This paper presents a condensed history of Library and Information Science (LIS) over the course of more than a century using a variety of bibliometric measures. It examines in detail the variable rate of knowledge production in the field, shifts in subject coverage, the dominance of particular publication genres at different times, prevailing modes of production, interactions with other disciplines, and, more generally, observes how the field has evolved. It shows that, despite a striking growth in the number of journals, papers, and contributing authors, a decrease was observed in the field's market-share of all social science and humanities research. Collaborative authorship is now the norm, a pattern seen across the social sciences. The idea of boundary crossing was also examined: in 2010, nearly 60% of authors who published in LIS also published in another discipline. This high degree of permeability in LIS was also demonstrated through reference and citation practices: LIS scholars now cite and receive citations from other fields more than from LIS itself. Two major structural shifts are revealed in the data: in 1960, LIS changed from a professional field focused on librarianship to an academic field focused on information and use; and in 1990, LIS began to receive a growing number of citations from outside the field, notably from Computer Science and Management, and saw a dramatic increase in the number of authors contributing to the literature of the field.

- Abstract
- This work identifies changes in dominant topics in library and information science (LIS) over time, by analyzing the 3,121 doctoral dissertations completed between 1930 and 2009 at North American Library and Information Science programs. The authors utilize latent Dirichlet allocation (LDA) to identify latent topics diachronically and to identify representative dissertations of those topics. The findings indicate that the main topics in LIS have changed substantially from those in the initial period (1930-1969) to the present (2000-2009). However, some themes occurred in multiple periods, representing core areas of the field: library history occurred in the first two periods; citation analysis in the second and third periods; and information-seeking behavior in the fourth and last period. Two topics occurred in three of the five periods: information retrieval and information use. One of the notable changes in the topics was the diminishing use of the word library (and related terms). This has implications for the provision of doctoral education in LIS. This work is compared to other earlier analyses and provides validation for the use of LDA in topic analysis of a discipline.

- Abstract
- Purpose - The purpose of this paper is to provide a close, detailed analysis of the frequency, nature, and depth of visible use of two of Foucault's classic early works, The Archaeology of Knowledge and The Order of Things, by library, and information science/studies (LIS) scholars. Design/methodology/approach - The study involved conducting extensive full-text searches in a large number of electronically available LIS journal databases to find citations of Foucault's works, then examining each citing article and each individual citation to evaluate the nature and depth of each use. Findings - Contrary to initial expectations, the works in question are relatively little used by LIS scholars in journal articles, and where they are used, such use is often only vague, brief, or in passing. In short, works traditionally seen as central and foundational to discourse analysis appear relatively little in discussions of discourse. Research limitations/implications - The study was limited to a certain batch of LIS journal articles that are electronically available in full text at UCLA, where the study was conducted. The results potentially could change by focussing on a fuller or different collection of journals or on non-journal literature. More sophisticated bibliometric techniques could reveal different relative performance among journals. Other research approaches, such as discourse analysis, social network analysis, or scholar interviews, might reveal patterns of use and influence that are not visible in the journal literature. Originality/value - This study's intensive, in-depth study of quality as well as quantity of citations challenges some existing assumptions regarding citation analysis and the sociology of citation practices, plus illuminating Foucault scholarship.
