Title

Online citation analysis : a methodological approach

Source

Scientometrics. 37(1996) no.1, S.39-62

Year

1996

Abstract

Investigates the possibilities and limitations of online citation analysis. The Dialog online processing tools RANK, MAP and TARGET are used to perform analysis of citations to and from isolated sets of documents as well as to carry out diachrone journal analysis. Discusses the implications of this analysis on the journal impact factors of ISI journals. Suggests that by the combined application of RANK and TARGET, a hitherto overlooked possibility of the online analysis of bibliographic coupling and mapping of scientific fields has been revealed
