Eigenfactor and Article influence score

Washington University indicators that use JCR data to calculate metrics and serve to complement other indicators such as the impact factor.

The Eigenfactor determines the influence of a journal. Article influence, is based on the Eigenfactor score and measures the importance of an article published in a journal. 

 

Eigenfactor

  • A "relational" indicator, similar to Google's PageRank, which measures the global influence of ego magazinesurnto the Citation Report (JCR). Calculates the level of citations received by a journal in a given period (citations received by articles published in the last 5 years in the current year), depending on whether the citations come from more or less cited journals and therefore more or less influential.
It is considered that a magazine is more influential if it receives citations from other miscellaneous magazines.

Article influence score

  • It measures the average influence of a journal article in the next 5 years after its publication and is calculated based on the Eigenfactor, that is, dividing the Eigenfactor of a journal by the number of articles published by the journal. .
Both metrics are based on JCR (Science Citation Index Expanded - SCIE and Social Science Citatoin Index - SSCI) data and exclude journal and proceedings data from the Arts and Humanities Citation Index, the Conference Proceedings Citation Index, the Book Citation Index and the Emerging Sources Citation Index).
