课程本体是课程知识组织的一种重要技术,在智能学习系统中得到广泛应用。针对人工建立课程本体依赖专家经验和效率较低等问题,提出课程本体自动构建技术。该技术以丰富的Web课程资源为数据源,集成网络爬虫、中文分词和关联规则挖掘等技术,实现课程本体自动构建。实验结果表明,该技术建立的课程本体不仅具有较好的质量,而且执行效率较高。

The course ontology used in the artificial intelligent learning system widely is one of the important technologies for knowledge organization in courses.To solve the problems of manual technique to construct the course ontology,a novel technique was proposed to construct the course ontology automatically.The technique employes some techniques such as Web spider,Chinese character division,and relation rule mining,to extract the concepts and relations of the course ontology from diverse web course resources.By experimental evaluation,it is proved that the technique can construct the course ontol...
