This paper presents an overview of advanced bibliometric methods for (1) objective and transparent assessment of strengths and weaknesses in research performance, and (2) monitoring interdisciplinary scientific developments. In the first application, we focus on the detailed analysis of research performance in an international comparative perspective. We demonstrate that advanced bibliometric m...

Bibliometrics has become an increasingly necessary tool for studying and analysing an institution's scientific activity. Research librarians must be able to extract, interpret and represent bibliometric data in different ways depending on the user to whom they are to be presented. In this article, we describe the process of creating a bibliometric data management and consultation tool, called B...

This chapter provides an introduction into the topic of visualizing bibliometric networks. First, the most commonly studied types of bibliometric networks (i.e., citation, co-citation, bibliographic coupling, keyword co-occurrence, and co-authorship networks) are discussed, and three popular visualization approaches (i.e., distance-based, graph-based, and timeline-based approaches) are distingu...

This study provides an historical analysis of the discipline of information retrieval for three time periods: 1980-1984, 1990-1994, and 2000-2004. This analysis is done through the use of a novel bibliometric technique called tri-occurrence analysis, in which the descriptor “information retrieval” is used as a filter term within the traditional technique of cooccurrence analysis. The resulting ...

In the analysis of bibliometric networks, researchers often use mapping and clustering techniques in a combined fashion. Typically, however, mapping and clustering techniques that are used together rely on very different ideas and assumptions. We propose a unified approach to mapping and clustering of bibliometric networks. We show that the VOS mapping technique and a weighted and parameterized...

Scientific research needs lots of literature searches that cost a large amount of time and energy. Bibliometric techniques could help us find research hotspots and grasp the research direction yet can’t reveal huge hidden information in massive literature since the existing bibliometric analysis techniques employ mainly simple statistical analysis techniques. Hence, we propose to introduce data...

Objective. The purpose of this work is to analyse the knowledge structure and trends in scientific research in the Online Information Reviews journal by bibliometric analysis of key words and social network analysis of co-words. Methods.

We address the question how citation-based bibliometric indicators can best be normalized to ensure fair comparisons between publications from different scientific fields and different years. In a systematic large-scale empirical analysis, we compare a traditional normalization approach based on a field classification system with three source normalization approaches. We pay special attention t...

BACKGROUND The h index bibliometric indicator for evaluating scientists and scientific institutions plays an increasingly important role in evaluating contemporary scientific research, including chemistry. RESULTS Citations are meaningful. The best way of measuring performance is to use the informed peer review, where peers judge on the base of a bibliometric report, once the limits and advan...

Introduction The scientific community has developed many institutionalized forms of evaluation where peer review has an important role, but recently, bibliometric methods have been gaining some acceptability to assess the scientific performance. The two techniques have been related to one another in different ways: 1) bibliometric methods have been used to analyze the peer review processes (Moe...
