The aim of this study is to analyze to which extent the Journal Impact Factor (JIF) reflects the amount of excellent publications contained in a journal in the corresponding subject category. We are introducing two percentile-based indicators in order to measure the excellence contribution at journal level. Calculations of these indicators have bee...
In the nineties of the last century, researchers have applied several indicators to study reference literature of scientific articles. Glänzel and Schoepflin (1999) was the first time to capture and understand the subject characteristics in terms of structure and ageing of cited literature in the sciences and social sciences. Following and extendin...
This study uses mixed methods—classical citation analysis, altmetric analysis, a survey with researchers as respondents, and text analysis of the abstracts of scientific articles—to investigate gender differences in the aims and impacts of research. We find that male researchers more often value and engage in research mainly aimed at scientific pro...
Interdisciplinary research figures high on today’s policy agendas. This short introduction and overview sketches the complexity of defining and mapping the nature of interdisciplinary research (IDR). The paper focuses on the different approaches to IDR and different methods applied in bibliometric studies that allow measuring it. These methods shou...
This study uses mixed methods – classical citation analysis, altmetric analysis, a survey with researchers as respondents, and text analysis of the abstracts of scientific articles – to investigate gender differences in the aims and impacts of research. We find that male researchers more often value and engage in research mainly aimed at scientific...
Prof. Zeyuan Liu was the first to introduce the concept of knowledge-domain mapping to the scientific community in China. Knowledge-domain maps are useful tools for tracking the frontiers of science and technology, facilitating knowledge management, and assisting scientific and technological decision-making. Science overlay mapping as a type of kno...
In this study we analyse the key driving factors of preprints in enhancing scholarly communication. To this end we use four groups of metrics, one referring to scholarly communication and based on bibliometric indicators (Web of Science and Scopus citations), while the others reflect usage (usage counts in Web of Science), capture (Mendeley readers...

The objective of this paper is to explore the impact of preprints in scholarly and broader scientific communication. In particular, the following four indicators are used to examine the 508 arXiv and 5536 non-arXiv papers in three major journals in Library and Information Science: citations from Web of Science (WoS), Scopus and Google Scholar, usag...
As of the middle of April 2020, the unprecedented COVID-19 pandemic has claimed more than 137,000 lives 1. Because of its extremely fast spreading, the attention of the global scientific community is now focusing on slowing down, containing and finally stopping the spread of this disease. This requires the concerted action of researchers and practi...
In the present study we discuss the challenge of “Scientometrics 2.0” as introduced by Priem and Hemminger (2010) in the light of possible applications to research evaluation. We use the Web of Science subject category public, environmental and occupational health to illustrate how indicators similar to those used in traditional scientometrics can...

We intend to edit a Festschrift for Henk Moed combining a “best of” collection of his papers and new contributions (original research papers) by authors having worked and collaborated with him. The outcome of this original combination aims to provide an overview of the advancement of the field in the intersection of bibliometrics, informetrics, sci...
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...
Aims:
Comprehensive data on research undertaken in cardiovascular medicine can inform the scientific community and can support policy building. We used the publication output from 2004 to 2013 and the 2014 references to these documents, to identify research topics and trends in the field of cardiovascular disease.
Methods and results:
Text fragm...
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 granula...
The concern about predominance of basic discovery research and lack of translation into clinical medicine, and segregation between these research communities, led the authors to study these research communities through mapping networks of publications and cross-references. Cardiovascular research from 1993 to 2013 was published in 565 journals, inc...
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 an...
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 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...
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: increa...
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...
Continuous cell lines are widely used, but can result in invalid, irreproducible research data. Cell line misidentification is a common problem that can be detected by authentication testing; however, misidentified cell lines continue to be used in publications. Here we explore the impact of one misidentified cell line, KB (HeLa), on the scientific...
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 Character...
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...
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 themat...
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...
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 rece...
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 combin...
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...
This Letter to the Editor proposes to use the CSS method for classifying ranking results (e.g. from university rankings) into meaningful groups.
Aims The growing burden of cardiovascular disease requires growth in research and innovation. We examine world-wide participation and citation impact across the cardiovascular research landscape from 1992 to 2012; we investigate cross-fertilization between countries and examine whether cross-border collaboration affects impact.
Methods and Results...
Objective:
The purpose of this study is to introduce a new methodology in the field of substance abuse, namely, co-citation analysis, which uses the bibliographic references of publications to establish the main thematic areas being researched and to identify the seminal documents that have contributed to establishing the intellectual foundation o...
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...
Altmetrics have gained momentum and are meant to overcome the shortcomings of citation-based metrics. In this regard some light is shed on the dangers associated with the new “all-in-one” indicator altmetric score.
One of the most important requirements of building applicable models and meaningful indicators for the use of scientometrics at the micro and meso level is the correct identification and disambiguation of authors and institutes. Platforms like ResearcherID or ORCID with author registration providing high reliability but lower coverage now provide a...
A work strand planned by the Science Europe Working Group on Research Policy and Programme Evaluation aims at mapping the state of affairs in data collection and their use at European funding and research organisations. In particular, the project identifies and proposes solutions for issues experienced by the Member Organisations (MO) regarding col...

Background: Some bibliometric research has been carried out in sport sciences, but compared with other disciplines
there is still no intensive study at macro level, especially on international collaboration.
Aim: This study attempts to observe the status and trend of international collaboration in sport sciences at macro
level, and to look at its r...
Scientific mapping has now become an important subject in the scientometrics field. Journal clustering can provide insights into both the internal relations among journals and the evolution trend of studies. In this paper, we apply the affinity propagation (AP) algorithm to do scientific journal clustering. The AP algorithm identifies clusters by d...
Using the example of the ‘h-related’ publication dataset created for a previous study on the literature of Hirsch-type measures (Zhang et al. in J Informetri 5(3):583–593, 2011) and updated for the present paper, we attempt to study the robustness and dynamic evolution of ‘core documents’. With using two different methods that have been recently in...
An attempt is made to apply bibliographic coupling to journal clustering of the complete Web of Science database. Since the sparseness of the underlying similarity matrix proved inappropriate for this exercise, second-order similarities have been used. Only 0.12% out of 8282 journals had to be removed from the classification as being singletons. Th...
A hybrid search strategy, using lexical and citation based methods, is presented in this paper as a robust method to delineate the broad field of cardiovascular research. Overall, this study aims to provide scientifically reliable and accurate data driven evidence about cardiovascular research by establishing a dataset of published research in this...
Scientometricians have devoted much time to the analysis of the (almost mythical) relation between collaboration and citation impact. Several authors found positive correlation between collaboration and scientific productivity (Price and Beaver, 1966; Beaver and Rosen, 1979, Braun et al., 2001, Glänzel, 2002). These findings were extended by includ...
Interdisciplinary research is increasingly recognized as the solution to today's challenging scientific and societal problems, but the relationship between interdisciplinary research and scientific impact is still unclear. This paper studies the association between the degree of interdisciplinarity and the number of citations at the paper level. Di...
The objective of this article is to further the study of journal interdisciplinarity, or, more generally, knowledge integration at the level of individual articles. Interdisciplinarity is operationalized by the diversity of subject fields assigned to cited items in the article's reference list. Subject fields and subfields were obtained from the Le...
Recently an increasingly controversial discussion about the concepts of usage metrics and altmetrics got going at conferences and meetings in our field. While for a small group both concepts are clearly different, a large part of the community tends to regard usage metrics as a subset of altmetrics.From our point of view this use of terminology is...
This study examines the relationship between exposure to the Internet and changes in collaboration patterns across institutional and national borders. The number of years that have elapsed since an institution’s adoption of a domain name (
Dns
) is used as a proxy for Internet exposure. This proxy is then matched with institutional data on all pub...
The hybrid clustering approach combining lexical and link-based similarities suffered for a long time from the different properties of the underlying networks. We propose a method based on noun phrase extraction using natural language processing to improve the measurement of the lexical component. Term shingles of different length are created form...
In this position paper we discuss the current status of the core scientific journals in China. Based on discussions of journals' relation to a small group of full-text database providers, open access publishing and copyright problems, we conclude that ...
The analysis of the high end of citation distributions represented by its tail provides important supplementary information on the citation profile of the unit under study. In a previous study by Glänzel (2013a), a parameter-free solution providing four performance classes has been proposed. Unlike in methods based on pre-set percentiles, this meth...
Os padrões da atividade de publicação, do impacto da citação e comunicação, em geral, mudam ao longo da carreira de um cientista. A mobilidade e as mudanças radicais no ambiente de pesquisa de um cientista ou no seu perfil estão entre os fatores mais espetaculares que têm efeito sobre os padrões de colaboração individuais. Embora a bibliometria, ne...
This paper attempts to sketch the interrelation between information retrieval and scientometrics pointing at possible synergy effects provided by some recently developed bibliometric methods in the context of subject delineation and clustering. Examples of specific search strategies based on both traditional retrieval techniques and bibliometric me...
This paper seeks to map out the emergence and evolution of entrepreneurship as an independent field in the social science literature from the early 1990s to 2009. Our analysis indicates that entrepreneurship has grown steadily during the 1990s but has truly emerged as a legitimate academic discipline in the latter part of the 2000s. The field has b...
Many nations are adopting higher education strategies that emphasize the development of elite universities able to compete at the international level in the attraction of skills and resources. Elite universities pursue excellence in all their disciplines ...
In 2005, J.E. Hirsch proposed a new measure "to quantify an individual's scientific output". He called his measure, which is based on individual citation rank statistics, h-index. It was shown that the h-index correlates with other bibliometric indicators of ‘significance’ but it was also stressed that scientific performance can hardly…En 2005, J.E...
The objective of the present study is twofold: (1) to show the aims and means of quantitative interpretation of bibliographic features in bibliometrics and their re-interpretation in research policy, and (2) to summarise the state-of-art in self-citation research. The authors describe three approaches to the role of author self-citations and possib...
