Description

technical field [0001] The invention relates to a question-and-answer analysis and processing method and system based on an educational knowledge map, and belongs to the technical field of fusion of knowledge map technology and education. Background technique [0002] The question answering system based on knowledge graph has two core issues, front-end semantic understanding and back-end knowledge graph construction. The knowledge graph vividly describes the complex relationships between concepts and entities in the objective world in a structured form. At present, knowledge bases in various fields are gradually being constructed, but there is no educational knowledge map for primary and secondary school subjects. In the aspect of back-end knowledge graph construction, the present invention constructs an educational knowledge graph specifically for primary and secondary school subjects, and invents a knowledge point and relationship extraction algorithm in terms of front-en...
