See full text

A configuration includes: a morphological analyzer configured to analyze a text provided as an input in a form of natural language by a user; an intention-estimation processor configured to refer to an intention estimation model in which words and corresponding user's intentions to be estimated from the words are stored, to thereby estimate an intention of the user based on the text analysis results obtained by the morphological analyzer; an unknown-word extractor configured to extract, as an unknown word, a word that is not stored in the intention estimation model from among the text analysis results when the intention of the user fails to be uniquely determined by the intention estimation processor; and a response text message generator configured to generate a response text message that includes the unknown word extracted by the unknown-word extractor.
