Advanced Bibliometric Methods

The working group Advanced Bibliometric Methods (ABM) focuses its activities on developing and improving bibliometric methods and techniques. The working group also investigates bibliometric data sources.

Themes

The research program of the ABM working group consists of three themes:

  • Bibliometric indicators. This theme is concerned with the development, improvement, and interpretation of bibliometric indicators, in particular citation-based indicators for assessing research performance.
  • Bibliometric network analysis. This theme focuses on the use of network analysis, text mining, and visualization techniques for analyzing bibliometric networks. This theme also supports the development of the VOSviewer software.
  • Bibliometric data sources and data processing. This theme investigates and compares different data sources available for bibliometric analysis, such as Web of Science, Scopus, Google Scholar, and PubMed. In addition, new techniques for processing bibliometric data are developed, for instance for cleaning and standardizing bibliometric data.

The ABM working group has a strong application-oriented focus. In order to identify the most relevant and most challenging problems in bibliometric practice, the ABM working group is working closely together with CWTS B.V..
