    A comparison of two techniques for bibliometric mapping: Multidimensional scaling and VOS

    Get PDF
    VOS is a new mapping technique that can serve as an alternative to the well-known technique of multidimensional scaling. We present an extensive comparison between the use of multidimensional scaling and the use of VOS for constructing bibliometric maps. In our theoretical analysis, we show the mathematical relation between the two techniques. In our experimental analysis, we use the techniques for constructing maps of authors, journals, and keywords. Two commonly used approaches to bibliometric mapping, both based on multidimensional scaling, turn out to produce maps that suffer from artifacts. Maps constructed using VOS turn out not to have this problem. We conclude that in general maps constructed using VOS provide a more satisfactory representation of a data set than maps constructed using well-known multidimensional scaling approaches

    Mapping the Structure and Evolution of Chemistry Research

    How does our collective scholarly knowledge grow over time? What major areas of science exist and how are they interlinked? Which areas are major knowledge producers; which ones are consumers? Computational scientometrics – the application of bibliometric/scientometric methods to large-scale scholarly datasets – and the communication of results via maps of science might help us answer these questions. This paper represents the results of a prototype study that aims to map the structure and evolution of chemistry research over a 30 year time frame. Information from the combined Science (SCIE) and Social Science (SSCI) Citations Indexes from 2002 was used to generate a disciplinary map of 7,227 journals and 671 journal clusters. Clusters relevant to study the structure and evolution of chemistry were identified using JCR categories and were further clustered into 14 disciplines. The changing scientific composition of these 14 disciplines and their knowledge exchange via citation linkages was computed. Major changes on the dominance, influence, and role of Chemistry, Biology, Biochemistry, and Bioengineering over these 30 years are discussed. The paper concludes with suggestions for future work

    Information Retrieval across Information Visualization

    Get PDF
    This article presents the analytical and retrieval potential of visualization maps. Obtained maps were tested as information retrieval (IR) interface. The collection of documents derived from the ACM Digital Library was mapped on the sphere surface. Proposed approach uses nonlinear similarity of documents by comparing ascribed thematic categories and thereby development of semantic connections between them. For domain analysis the newest IT trend - Cloud Computing was monitored across time period 2007-2009. Visualization reflects evolution, dynamics and relational fields of cloud technology as well as its paradigmatic property

    VOSviewer: A Computer Program for Bibliometric Mapping

    Get PDF
    We present VOSviewer, a computer program that we have developed for constructing and viewing bibliometric maps. VOSviewer combines the VOS mapping technique and an advanced viewer into a single easy-to-use computer program that is freely available to the bibliometric research community. Our aim in this paper is to provide an overview of the functionality of VOSviewer and to elaborate on the technical implementation of specific parts of the program

    A Bibliometric Analysis of Islamic Accounting Research Indexed by Dimensions.ai

    Get PDF
    This bibliometric study investigated the current state of documents on Islamic accounting published by digital object identifier equipped journals from 1990 to 2020 listed in Dimension. The analysis focused on the trends of the keywords, authors and journals. The data analyzed were 556 publications of research publications in Dimension (https://dimension.ai). Search terms were \u27Islamic accounting\u27. The searches used to establish the study dataset were last updated on November 13, 2020. Descriptive statistical methods were used, and a bibliometric analysis was conducted using the R Biblioshiny to find out the bibliometric map. The number of articles discussing the theme of Islamic accounting has been quite extensive in years, along with the development of Islamic financial institutions. Many journals publish this theme, among which the top journal is the Journal of Islamic Accounting and Business Research. The most popular keywords used are Islamic, Accounting dan Financial. The most prolific author is Karim RAA, who has been writing since 1990. The country with the most popular and the most number of authors is Malaysia. This study provides an overview of trends in the most popular keywords, journals and authors in articles on the topic of Islamic accounting, thus providing information for researchers focused on research in the field of Islamic accounting. In the end, this theme has the potential to continue to be developed

    Software survey: VOSviewer, a computer program for bibliometric mapping

    Get PDF
    We present VOSviewer, a freely available computer program that we have developed for constructing and viewing bibliometric maps. Unlike most computer programs that are used for bibliometric mapping, VOSviewer pays special attention to the graphical representation of bibliometric maps. The functionality of VOSviewer is especially useful for displaying large bibliometric maps in an easy-to-interpret way. The paper consists of three parts. In the first part, an overview of VOSviewer's functionality for displaying bibliometric maps is provided. In the second part, the technical implementation of specific parts of the program is discussed. Finally, in the third part, VOSviewer's ability to handle large maps is demonstrated by using the program to construct and display a co-citation map of 5,000 major scientific journals
