Indicators

Basic bibliometric indicators

• number of publications and citations
• number of publications and citations per researcher
• average number of citations per publication
• self citedness
• uncitedness
• h-index
• impact factor (journals, Thomson Reuters)
• SCImago Journal Rank (SJR) indicator (journals, countries)

Advanced bibliometric indicators
are always normalised, the publications are compared to other publications in the same subject area, the same publication year and of the same document type.
Examples

• field normalised citation score, e.g. CPP/FCSm and MNCS (about these indicators, see: Waltman, L., Eck, N. J., Leeuwen, T. N., Visser, M. S. & Raan, A. F. J. (2011). Towards a new crown indicator: an empirical analysis. Scientometrics 87, 467–481.).
  
• field normalised most cited publications, Top 5%, the share of publications from a group of authors that belong to the 5% most cited publications, world average=1

Alternative bibliometric indicators
New publication models e.g. Open Access journals, e-print archives, personal home pages have led to proposals for alternative indicators.
Examples

• number of downloaded publications, visibiblity on the web e.g. PLoS Journals, Article-Level Metrics 
• F1000, post publication peer review of articles by leading scientists and F1000 Article Factor

Structural indicators

• publication patterns - sometimes visualised in maps (e.g. Citation Map in Web of Science) with connections between authors, subject areas, countries and organisations
