Abstract

A knowledge graph-based question answering method and apparatus, a computer device and a storage medium. The method comprises: obtaining a user question (101); searching for a plurality of target vocabularies from a preset knowledge graph according to the user question (102); constructing a target query graph according to the plurality of target vocabularies and ontology; and querying, in the preset knowledge graph, an answer corresponding to the user question according to the target query graph, and feeding back the answer (104). The knowledge graph contains a large amount of information, and the query range can be expanded, so that the accuracy of answers is improved; moreover, the ontology comprises concepts and interrelationships in a 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...
