Abstract

The invention provides a question and answer method, system and device based on natural language processing and a storage medium. The method comprises the steps of obtaining a question and answer instruction input after a user starts an intelligent service; carrying out semantic identification on the question and answer instruction, and obtaining the question features corresponding to the question and answer instruction according to the identification result, wherein the question features comprise the intention category keywords and the execution category keywords; analyzing each execution category keyword, performing matching connection on the intention category keyword and all the execution category keywords by adopting the AND, OR and NOT expressions, and calling the similar statements corresponding to the question and answer instruction from a preset database according to a matching result; and obtaining the preset numbers of the similar statements, and obtaining the reply information corresponding to the similar statements according to the preset numbers. The question and answer method based on natural language processing can solve the problems of low reply efficiency, high labor cost and high system maintenance professionality of manual customer services, and has the advantages of high identification accuracy and accurate reply.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a question answering method, system, device and storage medium based on natural language processing. Background technique [0002] With the development of artificial intelligence and big data technology, human-computer interaction systems are playing an increasingly important role in enterprise production and daily life. Natural language is a way of human-computer interaction, and the natural language processing technology developed along with it mainly includes two parts: speech recognition and semantic understanding. [0003] In the field of intelligent customer service, the focus is on semantic understanding. Traditional methods mainly use rule matching, keyword matching, machine learning and other methods for literal matching, which are suitable for small data set scenarios, but are easily disturbed by redundant information and ignore key negative word...
