Patent ID: 7231395

Claim:
A computer-implemented method for categorizing Resulting Pages into categories, comprising: designating a first category as commercial pages and a second category as informational pages; determining a quality score q(wi) for each Resulting Page; determining a transactional rating τ(w i )for each Resulting Page, deriving a propagation matrix P; determining a commercial score κ for each Resulting Page; filtering out all Resulting Pages that meet or exceed a commercial score threshold value; wherein the Resulting Pages that meet or exceed the commercial page threshold value are placed in the first category and all remaining Resulting Pages are placed in the second category, wherein the determining the transactional rating τ(w i ) comprises determining whether each Resulting Page meets select criteria, determining how strongly each Resulting Page meets the select criteria, determining a transactional score for each page, and determining the transactional rating for each page from the transactional score, and wherein determining a transactional score for each page comprises creating a vector for each Resulting Page αk(w i ), wherein each vector contains a plurality of elements αk n (w i ), wherein each of the plurality of elements αk n (w i ) is a Boolean value that reflects how strongly each of the Resulting Pages meets each of the select criteria.
