Semantic classification assignment device, semantic classification provision method, semantic classification provision program

摘要

PPROBLEM TO BE SOLVED: To provide a semantic classification device capable of improving precision in semantic classification. PSOLUTION: A characteristic weight table 3 holds a weight that features difference/similarity in semantic classification between a trailing function expression of word and a word related to the trailing function expression in advance, as a characteristic weight representing a relationship between the characteristic of text and semantic classification. A score calculation part 4 searches the table 3 with a characteristic of an interested word in the text that is accepted by an input part 2 as a key, and calculates a score and a semantic classification tag candidate for the word. A semantic classification means 5 selects a series with the maximum total sum of score from among the semantic classification tag candidate series and outputs a semantic classification result in which words in the input text are supplied with a semantic classification tag.
