Patent number: 8065298Abstract: A concept network that can be generated in response to a user query. Various embodiments include analysis of structure information, for example, where such information is based at least in part on Universal Resource Locators (URLs) of Web sites or data storage locations. A concept network may be used with a search tool where the search tool searches a plurality of sites (e.g., Web sites, data storage locations, etc.). In such an example, each site location is arranged with a node. Certain ones of the nodes are connected by at least one link. The concept network selects a portion of certain ones of the nodes based on the link, wherein the at least one link is used for content purposes.Type: GrantFiled: July 28, 2008Date of Patent: November 22, 2011Assignee: Microsoft CorporationInventors: Zheng Chen, Wei-Ying Ma, Shengping Liu
