1. A method of recognizing natural language in a dialogue system, the method comprising:
- parsing, by a processor, voice data of a user into syllables to generate an input set;
understanding, by the processor, user language using an input set of an initial domain generated before dialogue with the user and an extended input set of an extended domain generated upon dialogue with the user;
generating, by the processor, a response sentence based on a result of understanding the user language; and
generating, by the processor, user language based on the response sentence.

Abstract
A dialogue system uses an extended domain in order to have a dialogue with a user using natural language. If a dialogue pattern actually input by the user is different from a dialogue pattern predicted by an expert, an extended domain generated in real time based on user input is used and an extended domain generated in advance is used to have a dialogue with the user.

8. A method of recognizing natural language in a dialogue system, the method comprising:
-
parsing, by a processor, voice data of a user into syllables to generate an input set; generating, by the processor, an extended domain including an extended input set generated using an initial input set generated by predicting meanings necessary for a use environment and expressions corresponding thereto and associated language data of the initial input set before dialogue with a user, and understanding user language using the extended input set of the extended domain; generating, by the processor, a response sentence based on a result of understanding the user language; and generating, by the processor, user language based on the response sentence. - View Dependent Claims (18)
