Abstract: A vector acquisition method includes: inputting, into a learned model, at least one piece of text including at least two of a plurality of words obtained by dividing a compound, the compound being a word divisible into the plurality of words; outputting, from the learned model, an adjusted vector corresponding to at least one of the words obtained by dividing the compound in the input piece of text; and acquiring a compound vector corresponding to the compound using the adjusted vector output from the learned model. Classification accuracy of vectors corresponding to words can thereby be enhanced.

Abstract: In a semantic representation generation method, syntax data is generated by a superficial analysis on text data described in a natural language. A concept tag is provided to each morpheme based on the syntax data with reference to a CT system table in which concept information hierarchically and ambiguously representing a meaning of the morpheme for a part of speech. Provided is a first semantic tag indicating semantic information representing a semantic relation between a first phrase/sequence of phrases and a second phrase/sequence of phrases to a first pair made up of the first phrase/sequence of phrases corresponding to a predicate and the second phrase/sequence of phrases having a modification relation with the predicate based on the syntax data. Semantic representation data is generated based on the concept tag provided to each morpheme and the first semantic tag provided to the first pair.

Abstract: A similarity calculation apparatus according to the present invention includes: a name acquisition unit configured to acquire a first group name to which each word belonging to a first synonym group belongs and a second group name to which each word belonging to a second synonym group belongs; a name set generation unit configured to generate a first group name set and a second group name set; and a similarity calculation unit configured to calculate similarity between the first group name set and the second group name set. Therefore, even when a plurality of synonym groups are created, terms can be effectively unified.
