Abstract

The embodiment of the invention provides a query processing method and device and electronic equipment, and the method comprises the steps: generating an explicit query statement according to a querymessage input by a user; If a query result cannot be obtained in a knowledge graph according to the explicit query statement, generating an implicit query matrix according to the query message; Matching query results corresponding to the implicit query matrix in a knowledge set, wherein the knowledge set comprises the knowledge graph; And outputting the query result to the user. According to the method, the query accuracy and the recall rate can be greatly improved, and the cost of intelligent questions and answers can be greatly reduced.

Description

technical field [0001] The embodiments of the present invention relate to computer technology, and in particular to a query processing method, device and electronic equipment. Background technique [0002] With the continuous development of science and technology, more and more industries hope to use intelligent question and answer to reduce operating costs and improve operational efficiency. For example, intelligent customer service, intelligent consultation, and intelligent decision-making all rely on intelligent question-and-answer capabilities. Therefore, how to continuously improve the ability of intelligent question answering is a research hotspot. [0003] In the prior art, intelligent question answering is mainly realized by manually configuring templates or matching methods based on natural language understanding. Among them, the method of manually configuring templates needs to manually configure answer results for questions with different expressions. The match...
