The invention provides a knowledge graph construction method and system. According to the knowledge graph construction method and system, the method comprises the following steps: photographing corrected homework or test paper done by students and identifying the photo obtained by photographing to obtain question content and an answering result of the target question judged to be wrong, and analyzing to obtain knowledge points contained in the question content and starting an error answering step, thereby finally constructing a corresponding knowledge graph. The method and the system perform transverse and longitudinal mining of knowledge points and answering steps on the corresponding homework data and test paper data by applying an intelligent technology (such as MCM and other technologies), so that the knowledge graph construction reliability and accuracy about the preset object are improved.
Description
technical field [0001] The present invention relates to the technical field of artificial intelligence education, in particular to a method and system for constructing knowledge graphs. Background technique [0002] In the teaching process, the knowledge map of students can accurately reflect the level of knowledge mastery and knowledge mastery of students, and can also formulate targeted teaching plans according to the knowledge map of different students. At present, the construction of knowledge graphs is only a simple analysis and summary of students' homework data and test data, and it cannot conduct intelligent and vertically and horizontally in-depth intelligent mining and analysis of these homework data and test data, which is seriously serious. Reduced the reliability and accuracy of the knowledge graph. Contents of the invention [0003] Aiming at the defects existing in the prior art, the present invention provides a knowledge map construction method and system....
