Computer-implemented method for automatic training of a dialogue system, and dialogue system for generating semantic annotations
First Claim
1. A computer-implemented method for automatic training of a dialogue system, in order to generate semantic annotations automatically on the basis of a received speech input, the method comprising the following steps:
- receiving, by the dialogue system, at least one speech input in the course of an interaction with a user;
generating, by the dialogue system, a symbolic representation from the speech input by performing recognition on the received speech input;
registering and appraising, by the dialogue system, a sense content of the symbolic representation of the received speech input, by the symbolic representation being classified on the basis of a trainable semantic model, in order to make a semantic annotation available automatically for the received speech input;
controlling, by the dialogue system, a vehicle component based on the semantic annotation;
receiving, by the dialogue system, additional user information representing a function selection of a vehicle component by the user;
automatic learning of the sense content of the received speech input, by the dialogue system, on the basis of the additional user information, if a connection between the reception of the speech input and the additional user information is determined on the basis of a temporal and semantic correlation, or semantic correlation,repeating iteratively, by the dialogue system, the receiving of additional user information and automatic learning of the sense content of the received speech input until a termination condition is satisfied.

Abstract
An adaptive dialogue system and also a computer-implemented method for semantic training of a dialogue system are disclosed. In this connection, semantic annotations are generated automatically on the basis of received speech inputs, the semantic annotations being intended for controlling instruments or for communication with a user. For this purpose, at least one speech input is received in the course of an interaction with a user. A sense content of the speech input is registered and appraised, by the speech input being classified on the basis of a trainable semantic model, in order to make a semantic annotation available for the speech input. Further user information connected with the speech input is taken into account if the registered sense content is appraised erroneously, incompletely and/or as untrustworthy. The sense content of the speech input is learned automatically on the basis of the additional user information.

9. An adaptive dialogue system for use in a vehicle, which has been designed to generate semantic annotations automatically on the basis of received speech inputs, comprising a processor executing a program to function as:
-
an input interlace which is designed to receive at least one speech input in the course of an interaction with a user; recognition device which is designed to generate a symbolic representation from the speech input by performing recognition on the received speech input; and a semantic classifying device which is designed to register and classify the sense content of the symbolic representation of the received speech input on the basis of a trainable semantic model, to make a semantic annotation available automatically for the received speech input on the basis of the classification, an output interface which is designed to output a signal based on the semantic annotation to a vehicle component in order to control the vehicle component, wherein the input interface is further designed to receive additional user information representing a function selection of a vehicle component by the user, to automatically learn the sense content of the received speech input on the basis of the additional user information, if a connection between the reception of the speech input and the additional user information is determined on the basis of a temporal and semantic correlation or a semantic correlation, and to repeat iteratively receiving of additional user information and automatic learning of the sense content of the received speech input until a termination condition is satisfied. - View Dependent Claims (10, 11, 12, 13, 14, 15)
