融合多模态资源的教育知识图谱的内涵、技术与应用研究

Research on connotation,technology and application of educational knowledge graph based on multi-modal resources

传统的教育知识图谱研究多数面向文本资源,忽略了多模态资源对教育知识的解读作用及其自身丰富的特征表示。为了更好地推进后续研究工作,以多模态资源为切入点,对教育知识图谱进行综述。首先,介绍了知识图谱的概念和分类;其次,综述了教育知识图谱的内涵,对教育知识图谱的定义、分类及其构建框架进行梳理;结合以神经网络为代表的深度学习方式,对教育知识图谱的构建技术进行重点介绍;最后,总结了教育知识图谱的相关应用,并指出当前研究中存在的问题与未来的研究方向。

The traditional research on educational knowledge graph is mostly text-oriented and ignores the interpretation function of multimodal resources to educational knowledge and its rich characteristic representation.In order to promote the follow-up research work better,this paper reviewed the educational knowledge graph from the perspective of multi-modal resources.Firstly,it introduced the concept and classification of knowledge graph.Secondly,it introduced the connotation of the educational knowledge graph,summarized the definition,classification and construction framework of educational knowledge graph.Thirdly,combined with deep learning represented by neural network,it introduced the construction technology of educational knowledge graph.Finally,it summarized the specific application of the educational knowledge graph,pointed out the problems existing in current research and future research directions.
