Microsoft Goes After Google’s PageRank With BrowseRank
The paper describes the downside of Google’s PageRank algorithm and describes how Microsoft’s “BrowseRank” algorithm fills in the holes. BrowseRank uses browsing behavior, such as analyzing a user’s web browsing history for relational data, to add into the mix. In addition, the paper describes that they look at how long a user stayed on a particular page. They believe BrowseRank is much more reliable in “inferring page importance” than PageRank and TrustRank algorithms. Stephan at News.com does a nice job summarizing the research paper, which you can find more of at this page.
