Have your Google PageRank drop or rise recently ? Anyway, Microsoft just introduce Microsoft BrowseRank where the researchers and academic collaborators claims that BrowseRank will bring more human touch.

“The more visits of the page made by the users and the longer time periods spent by the users on the page, the more likely the page is important. We can leverage hundreds of millions of users’ implicit voting on page importance,” the researchers said in BrowseRank: Letting Web Users Vote for Page Importance, a paper from the SIGIR (Special Interest Group on Information Retrieval) conference this week in Singapore. Authors are Bin Gao, Tie-Yan Liu, and Hang Li from Microsoft Research Asia and Ying Zhang of Nankai University, Zhiming Ma of the Chinese Academy of Sciences, and Shuyuan He of Peking University.

PageRank Shortcoming

Microsoft researchers argues that Google PageRank has number of weakness.  For example:-

1. There are smart peoples out there that can fool with Google PageRank by building bogus websites called as link farm. A higher ranking page links to different sites so that other sites will appear higher in search engine results.
2. With PageRank, the indexing doesn’t take into account the time a user spend on a particular site. This is where Microsoft BrowseRank come in to take into account the user spend time, browsing behavior and etc.

“Experimental results show that BrowseRank can achieve better performance than existing methods, including PageRank…in important page finding, spam page fighting, and relevance ranking.
