AUTOMATIC QUESTION AND ANSWER METHOD AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO2017010652
Kind Code:
A1
Abstract:
An automatic question and answer device and a method therefor are disclosed. The automatic question and answer device comprises: a semantic parsing module for generating a first question sentence expressed in a formal language from an inputted natural language question sentence, and extracting, from a database, a first answer sentence to the first question sentence; and a question pattern template module for generating a second question sentence by applying, to a natural language question sentence, a question template included in a question pattern to which the natural language question sentence corresponds, among predetermined question patterns, and extracting, from the database, a second answer to the second question sentence. Accordingly, a user's request for information can be identified and an answer having high suitability can be outputted despite variations such as a change in word order or a replacement of a word in a natural language question sentence.
