基于学科知识图谱的教育知识服务模型构建研究

Research on the Construction of Educational Knowledge Service Model Based on Discipline Knowledge Graph

人工智能技术的不断提升使得教育知识服务向智能化发展。而学科知识图谱作为人工智能重要技术之一,既能优化教育知识的生产方式,又能为多种智能化的知识服务开展提供支撑。为满足当今教育用户多样化、个性化、精准化的需求,本文在分析学科知识图谱的内涵、构建框架基础上,从助力教育知识库形成、辅助智能化知识发现、支撑多项智能教育知识服务开展三个方面讨论了学科知识图谱与教育知识服务的适切性。随后分析了教育知识服务的构成要素,在此基础上构建了基于学科知识图谱的智能化教育知识服务模型,并从需求采集、服务构建、服务应用、服务评估四个阶段对模型进行了阐释,最后提出了模型的相关实施建议。

The continuous improvement of artificial intelligence technology makes the educational knowledge services develop towards intelligence.As one of the important technologies of artificial intelligence,the discipline knowledge graph can not only optimize the production mode of educational knowledge,but also provide support for the development of a variety of intelligent knowledge services.Therefore,in order to meet the diversified,personalized and accurate demands of today’s education users,this paper,based on connotation analysis of discipline knowledge graph and framework construction,discussed the relevance of discipline knowledge graph and educational knowledge service from the following three aspects:to help to build the educational knowledge base,to promote intelligent knowledge discovery,and to provide support for the development of multiple intelligent educational knowledge services.Then it analyzed the components of educational knowledge service,built an intelligent educational knowledge service model based on discipline knowledge graph,and explained the model from four stages of demand collection,service construction,service application and service evaluation.Finally,it put forward relevant implementation suggestions of the model.
