Classification: CPC G | IPC G

Claim 11:
12. A learning data generation method in a learning data generation device for generating learning data for training of a machine learning model for predicting an utterance type of an utterance, the learning data generation method comprising:
automatically sorting the retrieved utterance data, based on the utterance types and the dialogue scene included in the retrieved utterance data, according to whether the dialogue scene included in the retrieved utterance data is included in the dialogue scenes that do not include utterances similar to utterances of the utterance type to be predicted prescribed in the predetermined sorting definition data stored in the memory, thereby excluding the retrieved utterance data from the targets for generation of the learning data when the dialogue scene included in the retrieved utterance data is included in the dialogue scenes that do not include utterances similar to utterances of the utterance type to be predicted prescribed,
wherein the memory is configured to store predetermined sorting definition data prescribing:
dialogue scenes that include utterances of the utterance type to be predicted,
dialogue scenes that include utterances similar to utterances of the utterance type to be predicted, and
dialogue scenes that do not include utterances similar to utterances of the utterance type to be predicted; and

generate, based on the sorted utterance data, the learning data for use in the training of the machine learning model.
