<P>PROBLEM TO BE SOLVED: To provide an interclause relationship estimation device that can extract relationship in a complex sentence without depending only on a conjunction sign or syntax structure, and to provide a computer program. <P>SOLUTION: The device is provided with: a relational parameter storage section where the device stores a combination of semantic categories related to a clause pair in association with the relationship with the clause pair; a section for adding the relationship with a clause pair that adds data indicating the relationship with the clause pair to data of the clause pair obtained from text data; a semantic category estimation section that performs processing for estimating the semantic categories of clauses included in the clause pair by using a rule for estimating the semantic categories of clauses, and adds data indicating the semantic categories of the estimation result to the clauses; and an approval processing section that calculates the co-occurrence frequency of the combination of the semantic categories corresponding to the clause pair and the relationship with the clause pair added by the section for adding the relationship with a clause pair, and writes the combination of the semantic categories having a significance probability within a predetermined range in association with the relationship with the clause pair into the relational parameter storage section. <P>COPYRIGHT: (C)2009,JPO&INPIT |
