Comparing capture, usage and citation indicators: an altmetric analysis of journal papers in chemistry disciplines

Pei-Shan Chi, Juan Gorraiz, Wolfgang Glänzel

Scientometrics > 2019 > 120 > 3 > 1461-1473

In this paper we extend the perspective of the scholarly impact from the traditional citations to other forms of scientific communication among scholars in the mirror of the PlumX and Web of Science (WoS) data. There are in total eight indicators out of three categories including Captures, Citations, and Usage analysed in the study. The results of this study shows that Captures and Usage indicators...

The role of baseline granularity for benchmarking citation impact. The case of CSS profiles

Wolfgang Glänzel, Bart Thijs

Scientometrics > 2018 > 116 > 1 > 521-536

In this paper we study the effect of granularity on Characteristic Scores and Scales (CSS). Unlike the traditional indicators that are mostly based on means and quantiles, CSS require the reduction of the citation distributions collaboration of the underlying reference population to four states (classes) and thus higher a different level of granularity. While the question of the choice of granularity...

Comparison of citation and usage indicators in research assessment in scientific disciplines and journals

Pei-Shan Chi, Wolfgang Glänzel

Scientometrics > 2018 > 116 > 1 > 537-554

Proceeding from the results of an earlier pilot study usage and citation impact data from the 2013 annual volume of the Web of Science Core Collection were collected and used to build indicators. Besides basic indicators on citation impact, usage counts and international collaboration, we applied the method of Characteristic Scores and Scales to analyse the distributions of citations and usage counts...

Which differences can be expected when two universities in the Leiden Ranking are compared? Some benchmarks for institutional research evaluations

Lutz Bornmann, Wolfgang Glänzel

Scientometrics > 2018 > 115 > 2 > 1101-1105

The comparison of two universities in terms of bibliometric indicators frequently faces the problem of assessing the differences as meaningful or not. This Letter to the Editor proposes some benchmarks which can be used for supporting the interpretation of institutional differences.

The contribution of the lexical component in hybrid clustering, the case of four decades of “Scientometrics”

Bart Thijs, Wolfgang Glänzel

Scientometrics > 2018 > 115 > 1 > 21-33

The introduction of textual analysis and the use of lexical similarities already proved an important asset in science mapping. Earlier research showed the added value of hybrid document networks over link-based ones through the reduction of the extreme sparseness. However, it was only after the application of Natural Language Processing and phrase extraction that networks purely based on lexical similarities...

Scientometric research assessment in the developing world: A tribute to Michael J. Moravcsik from the perspective of the twenty-first century

Wolfgang Glänzel, Lin Zhang

Scientometrics > 2018 > 115 > 3 > 1517-1532

Proceeding from Moravcsik’s paradigmatic ideas of how to build indigenous capability and sustainable science systems in developing countries, we attempted to further focus on the peculiarities of the twenty-first century and the new challenges of globalisation. In doing so, we selected three particular topics deemed relevant in this context: increase of international visibility and reception by the...

Garfield number: on some characteristics of Eugene Garfield’s first and second order co-authorship networks

Wolfgang Glänzel, Mehmet Ali Abdulhayoǧlu

Scientometrics > 2018 > 114 > 2 > 533-544

In this note we give an overview of the first- and second-order collaboration network reflected by Eugene Garfield’s publications in scientific journals. Although he had only a quite limited number of co-authors and co-publications, his co-authors’ own collaboration networks generate a large world-wide and multidisciplinary coverage. The classical model of co-authorship network is the Erdős network...

An empirical investigation of the associations among usage, scientific collaboration and citation impact

Pei-Shan Chi, Wolfgang Glänzel

Scientometrics > 2017 > 112 > 1 > 403-412

In this study usage counts and times cited from Web of Science Core Collection (WoS) were collected for articles published in 2013 with Belgian, Israeli and Iranian addresses. We investigated the relations among three indicators related to citation impact, usage counts and co-authorship, respectively. In addition, we applied the method of Characteristic Scores and Scales (CSS) to analyse the distributions...

Lexical analysis of scientific publications for nano-level scientometrics

Wolfgang Glänzel, Sarah Heeffer, Bart Thijs

Scientometrics > 2017 > 111 > 3 > 1897-1906

In earlier studies (e.g. Glänzel and Thijs in Scientometrics, 2017) we have used components of text analysis in combination with link-based techniques to cluster documents spaces and to detect emerging research topics on the large scale. Taking up now the objectives of evaluative scientometrics, we attempt to link the textual analysis of small sets of individual scientific papers to evaluative bibliometrics...

Same data—different results? Towards a comparative approach to the identification of thematic structures in science

Jochen Gläser, Wolfgang Glänzel, Andrea Scharnhorst

Scientometrics > 2017 > 111 > 2 > 981-998

Science studies are persistently challenged by the elusive structures of their subject matter, be it scientific knowledge or the various collectivities of researchers engaged with its production. Bibliometrics has responded by developing a strong and growing structural bibliometrics, which is concerned with delineating fields and identifying thematic structures. In the course of these developments,...

A citation-based cross-disciplinary study on literature aging: part I—the synchronous approach

Lin Zhang, Wolfgang Glänzel

Scientometrics > 2017 > 111 > 3 > 1573-1589

We provide a view of the literature aging features in the sciences and social sciences, at different aggregation levels, of major fields, subfields, journals and individual papers and from different perspectives. Against to the wide belief that scientific literature may become more rapidly obsolete, we found that, in general, the share of more recent references were distinctly lower in 2014 than that...

A citation-based cross-disciplinary study on literature ageing: part II—diachronous aspects

Lin Zhang, Wolfgang Glänzel

Scientometrics > 2017 > 111 > 3 > 1559-1572

In the first part of our study (Zhang and Glänzel in Scientometrics, 2017) we provided a view of the literature ageing based on a synchronous approach. Taking up the ideas by Egghe (Scientometrics 27(2):195–214, 1993) and Glänzel et al. (Scientometrics 109(3):2165–2179, 2016) we extend our study in the second part by applying a diachronous approach on the basis of citing literature. For this purpose...

Using hybrid methods and ‘core documents’ for the representation of clusters and topics: the astronomy dataset

Wolfgang Glänzel, Bart Thijs

Scientometrics > 2017 > 111 > 2 > 1071-1087

Based on a dataset on Astronomy and Astrophysics, hybrid cluster analyses have been conducted. In order to obtain an optimum solution and to analyse possible issues resulting from the bibliometric methodologies used, we have systematically studied three models and, within these models, two scenarios each. The hybrid clustering was based on a combination of bibliographic coupling and textual similarities...

Improved author profiling through the use of citation classes

Bart Thijs, Koenraad Debackere, Wolfgang Glänzel

Scientometrics > 2017 > 111 > 2 > 829-839

The method of Characteristic Scores and Scales (CSS), previously developed for application at the macro- and meso-level, has been applied to individual author statistics. In particular, two datasets have been used. Firstly, authors with Thomson Reuters Researcher-ID, independently of the field where authors are publishing and, secondly, authors who are active in the field of scientometrics, independently...

The challenges to expand bibliometric studies from periodical literature to monographic literature with a new data source: the book citation index

Wolfgang Glänzel, Bart Thijs, Pei-Shan Chi

Scientometrics > 2016 > 109 > 3 > 2165-2179

This study aims to gain a better understanding of communication patterns in different publication types and the applicability of the Book Citation Index (BKCI) for building indicators for use in both informetrics studies and research evaluation. The authors investigated the differences not only in citation impact between journal and book literature, but also in citation patterns between edited books...
