One of the most significant inaccuracies of bibliometric databases is that of omitted citations, namely, missing electronic links between a paper of interest and some citing papers, which are (or should be) covered by the database. This paper proposes a novel approach for estimating a database’s omitted-citation rate, based on the combined use of 2 or more bibliometric databases. A statistical ...
The paper is written with the assumption that the purpose of a mathematical theory of citation is to explain bibliometric regularities at the level of mathematical formalism. A mathematical formalism is proposed for the appearance of power law distributions in social citation systems. The principal contributions of this paper are an axiomatic characterization of citation distributions in terms ...
Demonstrating scholarly impact is a matter of growing importance. This paper reports on a bibliometric and altmetric analysis conducted on the Journal of Community Informatics (JOCI). Besides the bibliometric analysis the study also looked into JOCI article-level metrics by comparing usage metrics (article views), alternative metrics (Mendeley readership), and traditional citation metrics (Goog...
In recent years there is a small but increasing number of articles presenting and/or analyzing the scientific production from discrete geographical regions on a certain scientific topic. These articles applied the so-called bibliometric methods in order to evaluate the contribution of different countries in a scientific research field. In the present work, the research output of all countries i...
The impact factor of scientific reviews, calculated by the Institute for Scientific Information (ISI), is increasingly used to evaluate the performance of scientists and programmes. Bibliometric indicators, originally designed for other purposes than individual evaluation, are very useful tools provided their interpretation is not extrapolated beyond their limits of validity. Here we present a ...
Bibliometric techniques are not yet widely used to enhance retrieval processes in digital libraries, although they offer value-added effects for users. In this workshop we will explore how statistical modelling of scholarship, such as Bradfordizing or network analysis of coauthorship network, can improve retrieval services for specific communities, as well as for large, cross-domain collections...
Since 1996, hyperlinks have been studied extensively by applying existing bibliometric methods. The Web impact factor (WIF), for example, is the online counterpart of the journal impact factor. This paper reviews how this linkbased metric has been developed, enhanced and applied. Not only has the metric itself undergone improvement but also the relevant data collection techniques have been enha...
Bibliometric analysis has a long tradition in the context of scientific communication (Hood and Wilson 2001). In current discussions related to the impact of research results one can observe a more economically driven perception of bibliometric and scientometric indicators. Therefore the statistical methods and the conceptual framework involved must be understood and interpreted adequately. Thi...
Background and Objective: Violence against women is a global public health problem. Although there has been much research done on violence against women, there are few studies that provide the current scientific production. Method: In this study, bibliometric analysis has been used to evaluate the 1984 documents from 1986 to 2020 based on the Scopus database. These documents were analyzed quan...
in bibliometric and scientometric studies, three approaches of multivariate analysis, namely factor analysis, cluster analysis and multidimensional scaling are the most used methods. this article aims to review the use and applications of these techniques.
