Publication number: 20240242026Abstract: Synonyms are efficiently extracted from document data with high accuracy. A synonym determination system acquires correct/incorrect information that is information indicating whether or not two constituent words of a part of a plurality of synonym candidates that are a combination of two words selected from a plurality of words extracted from document data are synonyms, generates a synonym extraction rule that is information for determining whether or not the two constituent words of the synonym candidates are synonyms on the basis of a feature of the synonym candidates acquired from the document data and the correct/incorrect information, and extracts the synonym candidates of which the two constituent words are synonyms by applying the synonym extraction rule to the synonym candidates for which the correct/incorrect information has not been acquired. The correct/incorrect information is acquired, for example, by being received from a user via a user interface.Type: ApplicationFiled: April 26, 2022Publication date: July 18, 2024Inventors: Shotaro AGATSUMA, Eri TERUYA, Tadashi TAKEUCHI

Publication number: 20200097552Abstract: Provided is a synonym determination method to improve the determination accuracy of synonyms and reduce data and work. By executing the attribute tag attaching program 21, the CPU 11 attaches an attribute tag to a word extracted from the document data 31. By executing the word co-occurrence index calculation program 22, the CPU 11 calculates a co-occurrence index between words. By executing the attribute-related word search program 23, when there is a set of words having the same attribute among words whose co-occurrence index calculated between words having attributes related with each other is equal to or more than the lower limit value, the CPU 11 determines the set of words to be synonymous. By executing the synonym registration program 24, the CPU 11 presents the words determined to be synonymous to the user 3 as synonym candidates and registers the words presented in the synonym dictionary.Type: ApplicationFiled: July 29, 2019Publication date: March 26, 2020Applicant: HITACHI, LTD.Inventors: Takaaki Haruna, Tadashi Takeuchi, Takuya Oda
