Abstract (en)
[origin: WO2019011356A1] The invention relates to a method for conducting dialog between human and computer by means of a self-learning system, comprising: receiving user inputs in natural spoken text, associating synonyms and key words and making word associations, analyzing the user inputs with respect to sentence structure and sentence construction and recognizing same, associating key phrases, determining and classifying the user intention, checking if a confirmation is required, carrying out logical processing in a reasoning-and-answer preparation with formulation of a decision on the further dialog development, formulation or the dialog course with possible generation of an answer, wherein in order to recognize the user intention the statistical relevance of the association with a target intention is determined while at the same time all meta-information is retained, the classification occurs by means of a classification algorithm for intention clarification, logic and speech understanding are linked by means of meta-information in the decision tree, feedback to the self-learning system is generated by using earlier user questioning, a query to the user as to whether the recognized intention was correctly understood is generated if the statistical relevance is below a limit value, in this case an answer of the user is received and is then analyzed with respect to sentence structure and sentence construction and the user inputs are again divided into substantive content and into meta-information about the user and the user intention is again determined and classified, the recognition result is output to the self-learning system, the self-learning system develops automatic system recommendations and/or decisions for improving the intention recognition across a plurality of user interactions and keeps same at hand for later use, initiates the generation of the spoken-text answer to the user if the statistical relevance exceeds a limit value, and otherwise triggers a further inquiry.
