Abstract

The invention relates to a knowledge graph mining method and system, and the method comprises the steps: obtaining a text, and carrying out the error correction of the text; according to a preset word list, performing word segmentation and part-of-speech tagging processing on the text after error correction processing to obtain words in the text and part-of-speech of the words; according to the words and the part-of-speech, identifying entities in the text, and according to the words, the part-of-speech and the entities, extracting attributes and relationships of the entities in the text. According to the method, entity linking is carried out according to the entities, knowledge fusion is carried out according to the entity linking result and the attributes and relations of the entities, and the knowledge graph is obtained, through the method, the problem that large hysteresis exists in knowledge updating of the knowledge graph in the related technology is solved, and the effect of updating the knowledge of the knowledge graph in time is achieved.

Description

technical field [0001] This application relates to the technical field of artificial intelligence, in particular to a method and system for mining knowledge graphs. Background technique [0002] Knowledge graph (Knowledge Graph) is called knowledge domain visualization or knowledge domain mapping map in the library and information industry. Analyzing, constructing, mapping, and displaying knowledge and their interrelationships have been widely used in many fields such as question answering, search, and recommendation. [0003] In related technologies, the knowledge map mining process requires manual participation. Knowledge map mining is to mine information offline to obtain new knowledge, and then update the new knowledge to the storage content of the knowledge map in a regular manner. There is a large lag in the knowledge update of the intelligent robot. For example, in the intelligent robot dialogue scene, the user often mentions a lot of new knowledge. Since the knowled...
