http://en.wikipedia.org/wiki/PageRank
PageRank: PageRank is a link analysis algorithm, named after Larry Page[1]
and used by the Google Internet search engine, that assigns a numerical
weighting to each element of a hyperlinked set of documents, such as the
World Wide Web, with the purpose of "measuring" its relative importance
within the set.

排名很靠前

PageRank algorithm
In 1976 a recursive impact factor that gives citations from journals with
high impact greater weight than citations from low-impact journals was
proposed.[28] Such a recursive impact factor resembles the PageRank
algorithm of the Google search engine, though the original Pinski and Narin
paper uses a "trade balance" approach in which journals score highest when
they are often cited but rarely cite other journals. A number of subsequent
authors have proposed related approaches to ranking scholarly journals.[29][
30][31] In 2006, Johan Bollen, Marko A. Rodriguez, and Herbert Van de Sompel
also proposed using the PageRank algorithm.[32] From their paper:
