基于细化度与相似度的课程知识图谱构建研究

Construction of Curriculum Knowledge Graph Based on Refinement and Similarity

针对目前基于概念相似度聚类的课程概念本体关系构建技术中层次关系划分精确度不足的问题,提出基于课程概念相似度与细化度的课程概念本体构建方法。在计算课程概念相似度的基础上,引入课程概念细化度指标,进一步提升了课程概念本体层次关系构建的准确性,提高了课程知识图谱的数据质量。最后通过课程知识导航服务平台,验证了该方法的有效性。

In view of the insufficiency of hierarchical relationship classification in the construction of ontology relationship based on conceptual similarity clustering,this paper proposes a method of constructing curriculum concept ontology based on the similarity and refinement of curriculum concept.On the basis of the similarity of the curriculum concept,the comparison of the refinement degree of the curriculum concept is introduced,which further improves the accuracy of the construction of the ontology level relationship of the curriculum concept and improves the data quality of the curriculum knowledge graph.Finally,the effectiveness of the method is verified by the course knowledge navigation service platform.
