Patent number: 8359311Abstract: A resource selection system is described for assisting a user in performing a task that includes multiple actions. At each stage of the task, the system presents a set resources from which the user may select to perform a subsequent action in the task. The system implicitly selects the set of resources based on context information that identifies the user's current informational needs. For example, the context information may be derived from textual information that is being presented on a user device, which the user is presumed to be viewing at the current time. In one implementation, the system selects the set of resources by computing language models for respective domains and respective entities. The system uses the language models to determine the relevance of the context information to each of the domains. The system then selects resources associated with domains that have been assessed as relevant.Type: GrantFiled: June 1, 2010Date of Patent: January 22, 2013Assignee: Microsoft CorporationInventors: Kuansan Wang, Emre M.

The data displayed in the document is updated whenever the information source is updated. A contribution module allows users to add data to the document, a validation module allows users to determine the validity of the data linked to in the document, and an expert ranking module allows users to rank the expert or contributor of the data in the document.Type: ApplicationFiled: December 17, 2010Publication date: June 21, 2012Applicant: Microsoft CorporationInventors: Yi-Chin Tu, Aleksey Sinyagin, Xiaoxin Yin, Wenzhao Tan, Li-wei He, Yi-Min Wang, Emre Kiciman, Chun-Kai Wang
