Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating responses using task-independent conversational systems are provided. In one example method, a response to a user text input is generated by updating a state of the conversation based on the user text input, generating a conversational (task-independent) output, and determining whether to provide a conversational response based on the conversational output, or to additionally generate a task-specific output.
Claims54
A method comprising:
- obtaining, by a computer-implemented dialogue system and during a conversation between the computer-implemented dialogue system and a user to complete a particular task, a text input from the user;
- and
- without receiving any additional text inputs from the user:
- obtaining, by the computer-implemented dialogue system, a state of the conversation with the user that has been updated based on the text input, wherein obtaining the state of the conversation includes:
- generating a semantic input representing the text input;
- and
- updating a previous state of the conversation based on the semantic input;
- generating, by the computer-implemented dialogue system and from the state, a conversational output that defines a conversational response to the text input that is independent of the particular task, wherein the conversational output includes a score distribution over a plurality of possible intent-slot value combinations;
- and
- determining, by the computer-implemented dialogue system and from at least one of the score distribution included in the conversational output or the state of the conversation, whether to (i) provide the conversational response to the text input or (ii) generate a task output that is specific to the particular task.
