Publication number: 20140095478Abstract: Disclosed are methods for returning to a user an answer to the question “what is <string>.” Concepts and classes to which the concepts belong are determined from a corpus, such as taxonomy. The concepts are mapped to categories according to the structure of the taxonomy. Homonyms for words are collected and scored according to likeliness of use. Concept vectors are assembled for the identified concepts based on articles in the corpus and social media usage. Words are evaluated for generic-ness and a generic score is associated therewith. In responding to a query, the generic-ness of the terms of the query is evaluated and additional context solicited if the terms are generic. Candidate homonym concepts for a string in the query are selected according to context vectors for the homonym concepts. One or more homonym concepts are selected and the one or more categories corresponding to these concepts are returned.Type: ApplicationFiled: September 28, 2012Publication date: April 3, 2014Applicant: Wal-Mart Stores, Inc.Inventors: Digvijay Singh Lamba, Omkar Deshoande, Xiaoyong Chai

Publication number: 20140082022Abstract: Methods are disclosed for converting a directed graph to a taxonomy using guidelines from a user. An initial tree is output from a first pruning step in which subtree preferences (and other weights) are applied to preserve or remove paths from a node to one or more levels of descendent nodes. Subtree preferences (and infoboxes) may specify rules for automatically generating recommendations during application to nodes. In a second pruning step, the directed graph is again processed with additional weightings applied to edges in the graph in accordance with the recommendations. The recommendations may be human defined. Recommendations may specify a recommended ancestor for a particular node and may include a weighting to be applied to the recommendation itself, if there are multiple conflicting recommendations for the same node. Recommendations may also specify what standard weight to apply to the edge of the best parent.Type: ApplicationFiled: September 19, 2012Publication date: March 20, 2014Applicant: Wal-Mart Stores, Inc.Inventors: Digvijay Singh Lamba, Omkar Deshpande

Patent number: PP18315Abstract: The present invention relates to the development of a unique inflorescence bearing mutant plant type lli/lli (LEAF-LESS INFLORESCENCE). Further the present invention relates to the development of a unique inflorescence bearing mutant plant type lli/lli (LEAF-LESS INFLORESCENCE) through chemical mutagenesis. The present invention relates to the development of a new and distinct plant type for floricultural usage. The new type is a monogenic Mendelian recessive stable mutant plant of Catharanthus roseus with a novel leafless inflorescence architecture with increased flower frequency. This distinct plant of Catharanthus roseus was developed through chemical mutagenesis followed by salt tolerance selection.Type: GrantFiled: May 4, 2004Date of Patent: December 18, 2007Assignee: Council of Scientific and Industrial ResearchInventors: Sushil Kumar, Shashi Pandey Rai, Sanjay Rai Kumar, Digvijay Singh, Suchi Srivastava, Raghvendra Kumar Mishra
