Title:
UTTERANCE GENERATION DEVICE, UTTERANCE GENERATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/186525
Kind Code:
A1
Abstract:
Provided is a technology for generating an utterance on the basis of data indicating the context of a conversation. The technology includes: a phrase extraction unit that generates a phrase collection, which is a collection having, as elements, phrases that include context items and sets of the values of the context items extracted from an input text that represents the utterances of a user; a context understanding result update unit that uses the phrase collection and generates a post-update context understanding result indicating the latest context of the conversion based on a pre-update context understanding result indicating the context of the conversation at the current time; a conversation control unit that selects, as a similar experience, data about an experience class, on the basis of the similarity calculated between the post-update context understanding result and the data for an experience class included in an experience database, and uses the pre-update context understanding result and the post-update context understanding result to select, as an utterance template candidate, data about an utterance template class from an utterance template database; and an utterance generation unit that uses the post-update context understanding result, the similar experience, and the utterance template candidate, and generates an output text that is a response to the input text.
