Bibliometric analysis

Standard way of doing it:

  • Download database from WebofScience or Scopos
  • visualize with network viz tool 'Gephi'

Important tasks and challenges

  • Cleaning up data (duplicate authors/publications) - heuristics to identify different/same persons built in? (80/90% of the issue)
  • Multiple fields to analyze simultaneously
  • Merging WebofScience and Scopos (does not automatically add article references)
  • Orcid not yet default and standard (works for author to publications link but not the other way around). Is there a tool automatically checking this?
  • Merging institutions
  • Other networks where one can harvest bibliometric data? e.g. ResearchGate, Academia, Google scholar?
  • Limit with download reference entries (WebofScience - 500 per go, Scopus easier)
  • Clustering tasks - what are the different strategies and routines? (orthogonal, ...)
  • Classification of journals into themes (can be changing} - how to find links/important authors/institutes beyond co-authorship networks?
  • Topics classification by WebofScience - sometimes problematic, different from key word search
  • Account for time factor

What to evaluate

  • Impact analysis
  • altmetrics - broad network impact outside publications (news, social media ...)
  • Relevance over time, can it be normalized to some degree? Relation to GDP, number of employees per institution?
  • co-authorships
  • citation networks (x-order)
  • filter by internal citation in a community, not single high citations
  • Compare number of collective group citations vs. without self-citations

Example tools

  • VOSviewer to construct and visualize bibliometric networks
  • CitNetExplorer to visualize citation networks
  • Gephi - visualize networks, even over time
  • yEd - for layouting graphs
