Patent number: 7599931Abstract: A crawling system crawls a web site initially in a pattern detection phase and subsequently in a pattern usage phase. The pattern detection phase attempts to identify patterns of references to pages that contain informational content of interest and patterns of references to pages that contain little informational content of interest. During the pattern usage phase, the crawling system crawls the web site. When the crawling system encounters a reference contained on an accessed page, the crawling system determines whether the reference matches a reference pattern. If the reference matches a reference pattern associated with pages that contain informational content of interest, the crawling system accesses the referenced page. If, however, the reference matches a reference pattern of pages with little informational content, then the crawling system discards that reference without accessing the referenced page.Type: GrantFiled: March 3, 2006Date of Patent: October 6, 2009Assignee: Microsoft CorporationInventors: Bin Shi, Gu Xu, Wei-Ying Ma

Publication number: 20090228452Abstract: A method and system for identifying information about people is provided. The information system identifies groups of people that have relationships based on their relationships to documents or more generally to objects. The information system initially is provided with an indication of which people have which relationships to which documents. The information system then identifies clusters of people based on having a relationship to the same objects. The information system may also identify clusters of related objects associated with a cluster of people. When a user wants to identify information about a person, the user can provide the name of that person to the information system. The information system then can retrieve and display the names of the other people who are in the same cluster as the person.Type: ApplicationFiled: March 17, 2009Publication date: September 10, 2009Applicant: Microsoft CorporationInventors: Benyu Zhang, Wei-Ying Ma, Gu Xu, Hongbin Gao, Zheng Chen, Randy Hinrichs, Hua-Jun Zeng

Publication number: 20080215541Abstract: A search system provides various techniques for facilitating information retrieval. The search system may identify alternate queries for an initial query submitted by a user to a search system. Upon receiving the initial query, the search system identifies questions that are related to the initial query and presents to the user the related questions as alternate queries. The search system may also identify messages within a discussion thread that include answers. The search system may also identify an expert relating to the subject of a query by searching through expert profiles containing keywords of discussion threads in which the expert participated.Type: ApplicationFiled: March 1, 2007Publication date: September 4, 2008Applicant: Microsoft CorporationInventors: Hang Li, Gu Xu

The compositions comprise a styrene-allyl alcohol polymer and preferably at least one other polymer (e.g., cellulosic polymers) in addition to the styrene-allyl alcohol polymer. The inventive compositions can be used to protect contact or via holes from degradation during subsequent etching in the dual damascene process. The inventive compositions can also be applied to substrates (e.g., silicon wafers) to form anti-reflective coating layers having high etch rates which minimize or prevent reflection during subsequent photoresist exposure and developing.Type: GrantFiled: May 23, 2002Date of Patent: May 17, 2005Assignee: Brewer Science Inc.Inventors: Gu Xu, Jimmy D.

Patent number: 6756418Abstract: New polymers, compositions comprising these polymers, and methods of using these compositions are provided. The polymers comprise styrene and maleic anhydride monomers with at least some of the maleic anhydride monomers having certain functional groups bonded thereto. Preferred functional groups include those derived from adhesion promoters (e.g., 2-aminophenol), photoinitiators (e.g., 4-aminoacetophenone), and solubilizers (e.g., 4-aminobenzoic acid). The polymers can be incorporated according to conventional processes into compositions which are then used to form a color filter to be used in a liquid crystal display. The final color filter has a high resolution, is highly resistant to solvents typically used in the color filter manufacturing process, is strongly adhered to the color filter substrate, has superior optical clarity, is highly soluble in a wide range of alkali developers, and has excellent heat and UV light stability.Type: GrantFiled: June 7, 2002Date of Patent: June 29, 2004Assignee: Brewer Science Inc.Inventors: Gu Xu, Dan W.
