Abstract

A parsing section applies parsing processing to each of sentences, which is a target sentence and outputs parsing result candidates such as candidates of a modification relation of the sentence. A semantic analysis section performs semantic analysis processing on the target sentence and outputs semantic analysis result candidates such as candidates of a case frame of the sentence. A semantic analysis result determining section has a user interface for presenting the semantic analysis result candidates to a user so as to allow the user to select a correct semantic analysis result. A semantic analysis result is determined by the selection of the user. A parsing result determining section determines a parsing result based on the determined semantic analysis result and the analysis result information. A tagging section performs tagging with tags indicating syntactic information upon the target sentence on the basis of the determined parsing result.
