Patent number: 8606826Abstract: Methods, systems, and apparatus, including computer program products, operable to perform operations including receiving through a user interface with an interface language a search query having query terms; using the interface language to select one or more mappings and using the selected mappings to simplify each query term; and applying each simplified query term to a synonyms map to identify possible synonyms with which to augment the search query. In alternative embodiments, the operations include generating a synonyms map from a corpus of documents; where the synonyms map maps each of multiple keys to one or more corresponding variants, where each variant is associated with one or more of document languages. In alternative embodiments, the operations include generating a synonyms map from documents by applying document language-dependent mappings to words in the documents to generate keys for the map.Type: GrantFiled: January 12, 2012Date of Patent: December 10, 2013Assignee: Google Inc.Inventor: Ruchira S.

Publication number: 20130080545Abstract: A system is provided for automatically designating access and permission settings for documents in a collaborative authoring environment. The system may automatically configure the access and permission settings based on an email message with a link to a document for collaborative editing. The system may determine that certain recipient users in the “CC:” line of the email message be granted read only access while other recipient users in the “To:” line of the email message be granted editing access. Designating the access and privilege settings for the linked document in the email may be transparent to the sender and the recipients of the email. The system may automatically designate the access and privilege settings to the linked document for the recipients of the email without requiring any external input by the sender of the email.Type: ApplicationFiled: September 28, 2011Publication date: March 28, 2013Applicant: Microsoft CorporationInventor: Harmohit S.

Patent number: 7835903Abstract: Methods, systems, and apparatus, including computer program products, operable to perform operations including receiving from a user a search query; and receiving an indication of a user preference to apply transliteration in simplifying the query terms of the search query. Alternatively, the operations include receiving from a user a search query of query terms; applying transliteration in simplifying the query terms; and using the simplified query terms to identify synonyms to use in augmenting the search query. Alternatively, the operations include receiving from a user a search query; identifying the user interface language as a small language or not a small language; simplifying each query term to a simplified form; and if the user interface language is a small language, for each original query term that has a simplified form different from the original term, using the original query term as-is and not providing any synonyms for the query term.Type: GrantFiled: April 19, 2006Date of Patent: November 16, 2010Assignee: Google Inc.Inventor: Ruchira S. Datta

Patent number: 7475063Abstract: Methods, systems, and apparatus, including computer program products, operable to perform operations including receiving from a user through a user interface a search query comprising a query term, the search query having attributed to it a query language; deriving a simplified query term from the query term; and identifying one or more potential synonyms for the query term by looking up the simplified query term in a synonyms map, the synonyms map mapping each of a plurality of keys to one or more corresponding variants, each variant being a word associated with one or more document languages, and each variant being associated for each associated language with a variant-language score indicating a relative frequency of the variant among all variants for the associated language for the same key.Type: GrantFiled: April 19, 2006Date of Patent: January 6, 2009Assignee: Google Inc.Inventors: Ruchira S.

Patent number: 5250411Abstract: Disclosed are the DNA sequences of probes specific for Plasmodium vivax and the methods by which they were obtained. These nucleic acid sequences proved useful in detection of malaria in man caused by P. vivax by nucleic acid hybridization assays. The high sensitivity of these assays and the ease with which they can be performed enables them to be used for analyses of blood and other tissues of vertebrates and the invertebrates.Type: GrantFiled: December 4, 1990Date of Patent: October 5, 1993Assignee: Aktiebolaget AstraInventors: K.

Patent number: 5167375Abstract: A combination of raw coal and water is introduced as a slurry into a vessel. Chemicals are introduced at a feed inlet. The mixture is reduced by interaction with a bed of agitated grinding balls. Air is introduced into the lower portion of the vessel and forced upwardly through the circuitous passages among and between the grinding balls. The rising air bubbles carry the more hydropholic product upwardly into a froth compartment of the vessel and through a discharge outlet of the vessel. Wash water is introduced into the upper portion of the vessel and descends through the froth and the ball passages carrying entrained and less hydrophobic particles into the grinding chamber. The non-floatable material flows downwardly from the grinding chamber to a refuse zone for discharge as refuse from the vessel.Type: GrantFiled: May 7, 1990Date of Patent: December 1, 1992Inventor: Rabinder S. Datta

Patent number: 4130164Abstract: The efficiency of conversion of coal in the coal-gasification process is increased by pre-treatment of the coal to increase the fluid-permeability thereof. The reagent used for increasing the coal permeability is recoverable in high yield. Pre-treatment of bituminous coal by this process makes it possible to gasify coals of this rank effectively, such coals previously having been gasifiable only at low conversion efficiencies. Pre-treatment with a permeability-enhancing reagent is also useful as a step in the process of dissolving coal.Type: GrantFiled: August 11, 1977Date of Patent: December 19, 1978Assignee: Syracuse Research CorporationInventor: Rabinder S. Datta
