The present disclosure relates to techniques for automatically training a chatbot using utterances not understood by the chatbot itself and thus improve its understanding in a fast, effective and unsupervised way. This disclosure implements techniques to update known intents, to create new ones, and to modify the dialog manager so that new responses can be provided.
