Abstract

The invention relates to a knowledge graph-based question and answer method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a user question; searchinga plurality of target vocabularies from a preset knowledge graph according to the user questions; constructing a target query graph according to the plurality of target vocabularies and the ontology;and querying an answer corresponding to the user question in the preset knowledge graph according to the target query graph, and feeding back the answer. According to the embodiment of the invention,the knowledge graph contains a large amount of information, the query range can be expanded, so that the accuracy of answers is improved, and the ontology comprises concepts and interrelationships ina specific field, so that the constructed target query graph is more accurate, and the accuracy of the answers can be further improved.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a knowledge map-based question answering method, device, computer equipment and storage medium. Background technique [0002] Knowledge Graph, known as knowledge domain visualization or knowledge domain mapping map in the library and information industry, is a series of different graphics showing the knowledge development process and structural relationship, using visualization technology to describe knowledge resources and their carriers, mining , analyze, construct, map and display knowledge and their interconnections. A question answering system based on knowledge graphs can automatically find answers based on user questions. [0003] In related technologies, dependency syntax analysis is used to analyze user questions and build a dependency tree, and then find answers according to the dependency tree. If there is an error in the result of dependency parsin...
