Finally, the IR score is combined with PageRank to give a final rank to the document. 4.5 Searching The goal of searching is to provide quality search results efficiently. A number of results are from the whitehouse. The Effectiveness of GlOSS for the Text-Database Discovery Problem.
CitEc, citation analysis from items in the RePEc database. This of course erodes the advertising supported business model of the existing search engines. Database customization and filtration by a "personal information robot". As an example which illustrates the use of PageRank, anchor text, and proximity, Figure 4 shows Google's results for a search on "bill clinton".
