Problems solved by technology
[0003] However, the design of the existing knowledge map construction system is not reasonable enough, its autonomous learning ability is relatively poor, the early construction and learning take a long time, and it cannot be put into use in time, and the update of the constructed knowledge system is relatively slow. Therefore, we propose a mathematics-oriented The knowledge map construction method of the tutoring question answering system and its system are used to solve the above problems

The invention relates to the technical field of intelligent teaching, and discloses a knowledge graph construction method and system for a mathematical tutoring question-answering system. The method comprises the following steps: S1, promoting and popularizing software or applet integrated by the mathematical tutoring question-answering system; S2, searching related mathematical knowledge data through big data by the mathematical tutoring question-answering system; S3, analyzing the mathematical knowledge data obtained in step S2, extracting feature information, sorting the feature information, and recording the sorted feature information as a retrieval label of the mathematical knowledge data; and S4, enabling a user to input a to-be-queried mathematical problem through a mobile terminal.According to the invention, an initial system of mathematical knowledge is obtained through big data, a feedback mechanism is popularized and used when the system is put into use in the user, autonomous learning is carried out in an idle time period of a server, and an original knowledge system is updated and replaced in time according to user use feedback, so the mathematical knowledge system isensured to be gradually perfected and perfectly meet the consultation requirements of users.
Description
technical field [0001] The invention relates to the technical field of intelligent teaching, in particular to a method for constructing a knowledge map for a mathematics tutoring question answering system and a system thereof. Background technique [0002] Knowledge graph is the core key technology to realize automatic question answering and semantic search. The storage method of triples in the knowledge graph provides necessary and rich semantic information for information search and automatic reasoning of the system. Intelligent systems based on knowledge graphs can better implement semantic-based information search and relational reasoning, bringing users a better intelligent experience. At present, knowledge graph has become one of the core technologies for realizing intelligent systems. After retrieval, the Chinese patent application publication number CN111475629A discloses a knowledge map construction method and system for mathematics tutoring question answering sys...
