Eigenfactor
Eigenfactor (created by University of Washington scientists, Thomson Reuters)
The Eigenfactor score of a journal is an estimate of the percentage of time that library users spend with that journal. Borrowing methods from network theory, eigenfactor.org ranks the influence of journals much as Google’s PageRank algorithm ranks the influence of web pages. By this approach, journals are considered to be influential if they are cited often by other influential journals.
- Publications about EigenfactorThe Eigenfactor project has lead to numerous scholarly publications in several areas of research.
