Patent Document ID: 9530405
Application ID: 14413544

Base Claim:
1. An intention estimating device that estimates a user's intention from the user's language input, said intention estimating device comprising: an intention estimation unit extractor that splits the inputted language into a plurality of morphemes and extracts, from the morphemes, one or more intention estimation units each of which is a unit on which an estimation of said intention is to be performed, each of the intention estimation units consisting of one or more morphemes; an intention estimator that estimates a respective partial intention which indicates a respective intention for each of the intention estimation units extracted by said intention estimation unit extractor; an intention co-occurrence weight calculator that calculates an intention co-occurrence weight having a value which depends on a relationship between said partial intentions estimated by said intention estimator; and an intention sequence estimator that: generates an intention sequence corresponding to said inputted language by using one or more said partial intentions estimated by said intention estimator, and generates an intention estimation result corresponding to said inputted language by using both a score showing a likelihood of said generated intention sequence and the intention co-occurrence weight calculated for said partial intentions which construct said generated intention sequence.

Claim 5:
5. The intention estimating device according to claim 1 , wherein said intention estimating device includes an intention sequence conversion table that holds an intention sequence conversion rule for converting said partial intentions according to a relationship between a contiguous sequence of said partial intentions which construct said intention sequence, and an intention sequence convertor that converts said partial intention having a relationship matching the intention sequence conversion rule described in said intention sequence conversion table, among the contiguous sequence of said partial intentions which construct said intention sequence generated by said intention sequence estimator, according to said intention sequence conversion rule.
