摘要:
针对目前数学教学过程中,学生学习效率差,注意力难以集中等问题,提出了将知识图谱技术运用于数学教学中,构建关于数学内容的知识图谱,使得数学教学更加智能化,以提高学生的学习效率与学习兴趣。 首先介绍了本体构建的基本规则与一般知识图谱建立的基本方法,然后以数学教学内容为例,根据自然语言处理技术对数学知识进行了信息抽取,根据不同实体之间的共性语义相似度检测对实体进行了知识融合,减少实体的冗余和重复率以及图的复杂度。 对融合后的新知识,根据质量评估规则进行加工,将合格的部分加入到知识库中,然后依次迭代上述步骤更新数据库。 最后在Windows 平台下基于 Neo4j 引擎对知识图谱进行了可视化。 从而达到数学内容系统化、提高教学质量的目的
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 Neo4j engine,achieving the goal of systematizing the content of mathematics and improving the quality of teaching
