Detecting the intellectual structure of library and information science based on formal concept analysis

Abstract

Detecting intellectual structure of a knowledge domain is valuable to track the dynamics of scientific research. Formal concept analysis (FCA) provides a new perspective for knowledge discovery and data mining. In this paper we introduce a FCA-based approach to detect intellectual structure of library and information science (LIS). Our approach relies on the mathematical theory which formulates the understanding of ''concept'' as a unit of extension (scholars) and intension (keywords) as a way of modelling the intellectual structure of a domain. By analyzing the papers published in sixteen prominent journals of LIS domain from 2001 to 2013, the intellectual structure of LIS in the new century has been identified and visualized. Nine major research themes of LIS were detected together with the core keywords and authors to describe each theme. The significant advantage of our approach is that the mathematical formulae produce a conceptual structure which automatically provides generalization and specialization relationships among the concepts. This provides additional information not available from other methods, especially when shared interests of authors from different granularities are also visualized in concept lattice.Keywords Formal concept analysis Á Intellectual structure Á Library and information science Electronic supplementary material The online version of this article (

Does bibliometric research confer legitimacy to research assessment practice? A sociological study of reputational control, 1972-2016

“…The research specialty of evaluative bibliometrics has been studied repeatedly with scientometric mapping techniques [ 45 – 49 ]. This literature locates the area within the broader disciplinary category of library and information sciences [ 50 – 54 ]. Different methodological approaches have been pursued to identify substructures based on delineations, such as search terms or publications in key journals.…”

“…These studies converge in ECA being a core bibliometric research area since the introduction of the Science Citation Index (SCI) in the 1960s; as such, it can be distinguished from “visualization of knowledge domains” and “webometrics” [ 45 , 47 ]. In addition, “impact factor,” “h-index,” and “journal impact” are core keywords associated with citation analysis [ 50 ].…”

National and international trends in library and information science research: A comparative review of the literature

“…The other interesting finding of the study was the change of focus from the LIS organization to end-user and system development along with increased attention to evaluation and experimentation. Liu et al (2015) reviewed the 10,648 bibliographic records published in 16 leading LIS journals between 2001 and 2013. The paper used the formal concept analysis method to identify the intellectual structure of LIS.…”

Evolution of research topics in LIS between 1996 and 2019: an analysis based on latent Dirichlet allocation topic model

“…This approach enables researchers to examine a larger corpus of text data than content analysis and bibliometric methods. Liu et al (2015) investigated the intellectual structure of library and information science using the formal concept analysis (FCA) method. By analyzing the papers published in 16 prominent journals in the LIS domain from 2001 to 2013, the authors identified nine main LIS research themes: bibliometrics, scientometrics, and informetrics; citation analysis; information retrieval; information behavior; libraries; user studies; social network analysis; information behavior; and webometrics.…”

“…Content analysis was also a widely applied approach (Järvelin and Vakkari 1993;Koufogiannakis et al 2004;Blessinger and Frasier 2007). Today, an increased interest has shown in using model-based approaches to explore the intellectual structure of a domain (Sugimoto et al 2010;Liu et al 2015;Figuerola et al 2017). The method allows researchers to examine large document collections.…”
