融合多模态资源的教育知识图谱的内涵、技术与应用研究

he 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 better promote the follow-up research work, this paper reviews the educational knowledge graph from the perspective of multi-modal resources. Firstly, it introduces the concept and classification of knowledge graph. Secondly, it introduces the connotation of the educational knowledge graph, summarizes the definition, classification and construction framework of educational knowledge graph; Thirdly, combined with deep learning represented by neural network, it introduces the construction technology of educational knowledge graph. Finally, it summarizes the specific application of the educational knowledge graph, points out the problems existing in current research and future research directions.
