First Claim
Patent Images
1. A method of recognizing natural language in a dialogue system, the method comprising:
- by at least one hardware processor interfaced with a memory including instructions which control the at least one hardware processor to;
input voice data of a user;
parse the voice data of the user to generate a parsed input set;
determine whether the parsed input set is included in an initial domain including an initial input set generated before dialogue with the user and in an extended domain including an extended input set generated upon dialogue with the user;
provide an understood result comprising content based on at least one of the initial input set and the extended input set according to a result of the determination; and
output the understood result.

Abstract
A dialog system uses an extended domain in order to have a dialog with a user using natural language. If a dialog pattern actually input by the user is different from a dialog 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 dialog with the user.

8. A method of recognizing natural language in a dialogue system, the method comprising:
by at least one hardware processor interfaced with a memory including instructions which control the at least one hardware processor to; input voice data of a user; parse the voice data of the user to generate a parsed input set; generate 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; determine whether the parsed input set is included in an initial domain including the initial input set and in the extended domain; provide an understood result comprising content based on at least one of the initial input set and the extended input set according to a result of the determination; and output the understood result. - View Dependent Claims (18)

16. A dialogue system using an extended domain, the dialogue system comprising:
at least one hardware processor interfaced with a memory including instructions which control the at least one hardware processor to; parse voice data of a user to generate a parsed input set;
generate 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;determine whether the parsed input set is included in an initial domain including the initial input set and in the extended domain; provide an understood result comprising content based on at least one of the initial input set and the extended input set according to a result of the determination; and output the understood result.

19. A dialogue system using an extended domain, the dialogue system comprising:
at least one hardware processor interfaced with a memory including instructions which control the at least one hardware processor to; parse voice data of a user to generate a parsed input set; determine whether the parsed input set is included in an initial domain including an initial input set generated before dialogue with the user and in an extended domain including an extended input set generated upon dialogue with the user; provide an understood result comprising content based on at least one of the initial input set and the extended input set according to a result of the determination; generate a response sentence based on the understood result; and generate user language according to the response sentence by using the initial domain and the extended domain.
