Patent ID: 7860895

Claim:
A computer-implemented method, comprising: generating a representation of a network of online content sources, wherein said representation reflects navigation paths and respective navigation path weights among said online content sources, wherein different values of said navigation path weights are indicative of corresponding different levels of user activity among said online content sources, and wherein said user activity comprises a plurality of requests generated by a plurality of users to access individual ones of said online content sources; and dependent upon said navigation paths and respective navigation path weights, generating one or more interest spaces of said network, wherein each interest space includes at least a subset of said online content sources; wherein generating any particular one of said one or more interest spaces comprises: selecting a given one of said online content sources for inclusion in said particular interest space dependent upon user activity between said given online content source and some other online content source that is currently included in said particular interest space, wherein said user activity is indicated by one or more of said navigation paths and respective navigation path weights corresponding to said given online content source, and wherein selecting said given online content source for inclusion in said particular interest space occurs without dependence upon content included in said given online content source; wherein said selecting comprises determining whether a given navigation path relating said given online content source and said other online content source is a qualifying navigation path, and if said given navigation path is a qualifying navigation path, assigning said given online content source to said given interest space; wherein said determining whether said given navigation path is a qualifying navigation path includes determining whether a given navigation path weight corresponding to said given navigation path satisfies a selection criterion; wherein each of said generating a representation, said generating one or more interest spaces, and said generating a particular interest space is performed by one or more computer systems each comprising at least a processor and a memory.
