摘要： To improve prediction accuracy of utterance types in a dialog. A learning data generation device (10) according to the present invention comprises: a sort unit (11) configured to perform, based on information appended to utterances in a dialog amongst more than one speaker and that is indicative of a dialogue scene that is a scene in which the utterances in the dialog were made, sorting regarding whether the utterances are to be targets for generation of the learning data, wherein the sorter (11) is configured to exclude utterances of a dialogue scene that includes utterances similar to utterance of the particular type from the targets for generation of learning data.

摘要： The present invention makes it possible to efficiently create an appropriate dialogue history. This device for supporting creation of dialogue history (1) is provided with: a dialogue utterance focus point information store (19) which, according to utterance data indicating utterances, stores dialogue scene data indicating dialogue scenes of the utterances, utterance type indicating the types of the utterances, and utterance focus point information of the utterances; and an input/output interface (20) which, with respect to each of the dialogue scenes indicated by the dialogue scene data stored in the dialogue utterance focus point information store (19), causes a display device to display any one or more of utterances, utterance type, and utterance focus point information. Based on an operation input to the input/output interface (20), the dialogue utterance focus point information store (19) adds, modifies, or deletes any one or more of the dialogue scene data, the utterance type, and the utterance focus point information.

摘要： The learning data generation device (10) of the present invention comprises: an end-of-talk predict unit (11) for performing: a first prediction in which it is predicted, based on utterance information on an utterance in the dialog, using the end-of-talk prediction model (16), whether the utterance is an end-of-talk utterance of the speaker; and a second prediction in which it is predicted, based on one or more prescribed rules, whether the utterance is an end-of-talk utterance; and a training data generate unit (13) for generating, when, in the first prediction it is predicted that the utterance is not an end-of-talk utterance and in the second prediction it is predicted that the utterance is an end-of-talk utterance, for the utterance information on the utterance, learning data to which training data indicating that the utterance is an end-of-talk utterance is appended.

摘要： The end-of-talk prediction device (10) of the present invention comprises: a divide unit (11) for dividing, using delimiter symbols indicating delimitations within segments, a string in which the utterance in the dialog has been text-converted by speech recognition, the delimiter symbols included in the result of the speech recognition; and an end-of-talk prediction unit (12) for predicting, using an end-of-talk prediction model (14), whether the utterance corresponding to the divided string divided by the divide unit (11) is an end-of-talk utterance of the speaker.
