Patent ID: 7739209

Claim:
A method comprising: assigning one or more source score values to one or more seed nodes included in a seed set of nodes, wherein the seed set of nodes is representative of a topic; deriving a destination score value for a first web node based on a mapping of a reachability relationship between one or more seed nodes and the first web node; deriving a source score value for the first web node based on a mapping of a reachability relationship between the first web node and one or more evaluation nodes, each of the one or more evaluation nodes having, respectively, a derived destination score; determining, based at least in part on at least one of the destination score value of the first web node and the source score value of the first web node, that additional processing should be performed on the first web node; determining that additional processing should not be performed on a second web node; and classifying the content of the first web node.
