Abstract:
1. A machine-implemented method for extrapolating user profile information from user web page access patterns, comprising: detecting a set of web pages accessed by a test user having an unknown user profile attribute; mapping at least a subset of said detected web pages to a first data structure, said first data structure representing a web page access pattern of said test user; comparing said first data structure to a plurality of a second data structure to obtain a comparison result, the plurality of said second data structure representing clusters of web page access patterns of a sample data set of users having a known user profile attribute in common; evaluating based on said comparison result the plurality of said second data structure and said first data structure to identify a second data structure matching the web page access pattern of the first data structure; and assigning said unknown user profile attribute of said test user from the matching second data structure to said test user; wherein the known user profile attribute in common of the sample data set of users corresponds to the unknown user profile attribute of said test user; wherein said first and second data structures are multi-dimensional vectors; and wherein each dimension of said first and said second multi-dimensional vectors corresponds to a separate web page.
