Several [[Web search]] [[ranking]] algorithms use link-based centrality metrics, including (in order of appearance) [[Massimo Marchiori|Marchiori]]'s [[Hyper Search]], [[Google]]'s [[PageRank]], Kleinberg's [[HITS algorithm]], the [[CheiRank]] and [[TrustRank]] algorithms. Link analysis is also conducted in information science and communication science in order to understand and extract information from the structure of collections of web pages. For example, the analysis might be of the interlinking between politicians' web sites or blogs. | Several [[Web search]] [[ranking]] algorithms use link-based centrality metrics, including (in order of appearance) [[Massimo Marchiori|Marchiori]]'s [[Hyper Search]], [[Google]]'s [[PageRank]], Kleinberg's [[HITS algorithm]], the [[CheiRank]] and [[TrustRank]] algorithms.
