Syntax / semantic analysis result ranking model creation method and apparatus, program, and recording medium

摘要

PPROBLEM TO BE SOLVED: To create a syntax-semantic analysis result ranking model enabling to rank a syntax-semantic analysis result with high accuracy. PSOLUTION: A syntax-semantic analysis result ranking model creation method stores, in a storage unit 2, semantic information DB22 in advance, extracts, with a semantic information extraction unit 11A, a semantic analysis result from a syntax-semantic analysis result read from the storage unit, searches the semantic information DB22 in the storage unit 2 regarding a target phrase selected from a processing object sentence read from the storage unit, based on the semantic analysis result, thereby extracts semantic information related to the object phrase, and develops, with a feature creation unit 11E, the object phrase, based on the semantic information extracted with the semantic information extraction unit 11A to thus create a feature used for creation of the syntax-semantic analysis result ranking model 23.
