Patent number: 10354010Abstract: An information processing system to increase weights of words that are related to a text, but that do not explicitly occur in the text, in a weight vector representing the text, is provided. An adjusting system (100) includes a distance storing unit (110) and an adjusting unit (120). The distance storing unit (110) stores distances between any two terms of a plurality of terms. The distance between two terms becomes smaller as the two terms are semantically more similar. The adjusting unit (120) adjusts a weight of each term of the plurality of terms in a weight vector including weights of the plurality of terms and representing a text, on the basis of a distance between each term and other term in the weight vector and a weight of the other term.Type: GrantFiled: April 24, 2015Date of Patent: July 16, 2019Assignee: NEC CORPORATIONInventors: Daniel Georg Andrade Silva, Akihiro Tamura, Masaaki Tsuchida
