Abstract

The invention relates to artificial intelligence, and provides an intelligent question-answering method and device based on a knowledge graph, and computer equipment, and the method comprises the steps: receiving a question text online; extracting a first entity in the question text; searching a first node corresponding to the first entity in a preset knowledge graph; utilizing a preset intentionrecognition rule engine to recognize a first intention of the question text, the intention recognition rule engine being an engine established according to a Trie tree; searching a first answer corresponding to the question text in the knowledge graph by taking the first node as a starting point according to the first intention; and feeding back the first answer according to a preset mode. When intelligent questioning and answering are realized, intention recognition can be quickly carried out through an intention recognition rule engine established based on a Trie tree, and the feedback speedof a questioning and answering system is increased. The natural language is mapped to the knowledge graph for structured query, the query speed is higher, and the result is more accurate.

Description

technical field [0001] The present application relates to the field of artificial intelligence, and in particular to a knowledge graph-based intelligent question answering method, apparatus and computer equipment. Background technique [0002] The text-based question answering system uses the retrieval method to search for relevant information from the corpus, which has many defects. First, the corpus is stored in the form of original text in the corpus, and each corpus exists relatively independently, so there is no relationship between the corpus. Secondly, the information and knowledge contained in the corpus is scattered and has no hierarchy, so it is impossible to use information such as the correlation of knowledge itself and the upper and lower relationship in the question and answer to reason and generalize, and the speed of intention recognition is slow. SUMMARY OF THE INVENTION [0003] The main purpose of this application is to provide a question answering meth...
