Question answering processing method and intelligent equipment

Abstract

The invention discloses a question answering processing method and intelligent equipment. The method comprises steps of responding to a received target question inputted by a user, and obtaining a plurality of candidate questions similar to the target question and the answer information of the candidate questions; calculating a core word included in each question sentence in a first set, wherein the first set comprises a target question sentence and a plurality of candidate question sentences; forming new statements by the questions in the first set and the core words of the questions to obtain a second set; and calculating a matching candidate question with the highest probability score according to the second set, and outputting answer information corresponding to the matching candidatequestion. According to the method, interaction matching of the core words is utilized, even if only a certain word or only individual characters in the question are different, good question and answermatching capacity is achieved, the output answers are more accurate, and the generalization capacity of a current open domain question and answer system can be improved.

Description

technical field [0001] The invention relates to the technical field of open domain question answering, in particular to a question answering processing method and an intelligent device. Background technique [0002] The open domain question answering system is an important link in smart devices such as smart TVs, smart homes, and smart speakers. When users ask target questions through smart devices, the open domain question answering system can retrieve similar candidate questions and their answers from a large number of data sets. Then, by querying the similarity with the target question, the user is provided with the closest answer, thereby realizing the interactive question-and-answer between the smart device and the user. [0003] The open domain system can use the conventional interactive matching network model for question and answer processing, but the defect of this question and answer processing method is that if there is only a certain word or only individual words...

Problems solved by technology

[0003] The open domain system can use the conventional interactive matching network model for question and answer processing, but the defect of this question and answer processing method is that if there is only a certain word or only individual words in the question, the question and answer matching effect will be poor.

like figure 1 As shown, the user asks "Is it good to drink milk tea in the morning", the open domain system gives the answer "Drinking milk tea in the morning is good for the body", and then the user asks "Is it good to drink milk tea at night", and this question is only " The word difference between "early" and "late" may lead to the output answer may still be "drinking milk tea in the morning is good for the body", resulting in a wrong answer, so that the answer that the user expects cannot be given
