基于语义web在线学习资源管理的本体和元数据

摘要

构造了在线学习资源管理系统的本体和元数据.首先,在分析系统用例图的基础上,给出了网络在线学习资源和用户的顶层本体、RDF模式描述和类图,并从功能和运行2个方面对给出的学习资源本体和用户本体进行了评估;然后结合Dublin核心元数据和IEEE的LOM元数据模型,给出了本系统的元数据格式;最后通过实例证明了所给出的本体和元数据的有效性.%An ontology and metadata for online learning resource repository management is constructed.First,based on the analysis of the use-case diagram, the upper ontology is illustrated which includes resource library ontology and user ontology,and evaluated from its function and implementation;then the corresponding class diagram,resource description framework (RDF) schema and extensible markup language (XML) schema are given.Secondly,the metadata for online learning resource repository management is proposed based on the Dublin Core Metadata Initiative and the IEEE Learning Technologies Standards Committee Learning Object Metadata Working Group.Finally,the inference instance is shown,which proves the validity of ontology and metadata in online learning resource repository management.
