Construction of Knowledge Atlas Based on Mathematics Teaching
摘要
Abstract
Aiming at the problems of poor learning efficiency and difficulty in concentration of students in the current mathematics teaching, we put forward the application of knowledge map technology in mathematics teaching, and construct the knowledge map of mathematics content to make mathematics teaching more intelligent, so as to improve students' learning efficiency and interest. First we introduce the basic rules of ontology construction and the basic methods of establishing general knowledge map. Then with mathematics teaching content as an example, according to the natural language processing technology, the mathematical knowledge is extracted, and the knowledge is fused according to the detection of common semantic similarity between different entities, so as to reduce the redundancy and repetition rate of entities as well as the complexity of graphs. The new fused knowledge is processed according to the quality evaluation rules, and the qualified part is added to the knowledge base. Then the above steps are iterated to update the database. Finally, the knowledge map is visualized on the Windows platform based on the Neo4 j engine, achieving the goal of systematizing the content of mathematics and improving the quality of teaching.关键词
