Dialogue system and dialogue processing method
View Patent ↗It is an aspect of the present disclosure to provide a dialogue system capable of providing an extended function to the user by registering a new vocabulary that matches the user's preference and by changing the pre-stored conversation pattern.
1. A dialogue system comprising:
a microphone configured to receive a user's utterance;
a processor configured to:
determine that the user's utterance is an utterance asking a change of a predetermined ground rule in response to determining that a condition parameter and a result parameter are included in the user's utterance received by the microphone; and
in order to change the predetermined ground rule, set the condition parameter in the user's utterance as a user's utterance command, and set the result parameter as a command for controlling a device corresponding to the user's utterance command; and
a storage configured to store information related to the condition parameter and the result parameter set based on the predetermined ground rule,
wherein the processor is configured to: in response to determining that the condition parameter is included in the user's utterance received by the microphone, extract the condition parameter, identify the result parameter corresponding to the extracted condition parameter based on the information in the storage, generate a response based on the identified result parameter, transmit the command for controlling the device based on the identified result parameter, and output the generated response to a speaker.
2. The dialogue system according to claim 1 , wherein the processor determines whether the ground rule previously stored in the storage and the change of the predetermined ground rule collide with each other.
3. The dialogue system according to claim 2 , wherein the processor determines whether the change of the predetermined ground rule is applicable based on at least one of context information or a dialogue policy included in the storage.
4. The dialogue system according to claim 3 , wherein the processor determines the update of the storage based on a determination result of a collision and a determination result of the applicability.
5. The dialogue system according to claim 1 , wherein the processor registers a synonym or an antonym related with the condition parameter, or the result parameter to the storage based on a dialogue policy.
6. The dialogue system according to claim 1 ,
wherein the processor is configured to generate the response to the user's utterance based on a determination result of whether the change of the predetermined ground rule is applicable.
