基于本体的教育资源库的研究与设计

目前，我国的教育资源建设在共享性、重用性、资源检索查全率和查准率等问题上依然存在某些不足，为了解决当前检索系统中同义词难以识别、相关查找困难等问题，把本体引入到教育资源建设中，并提出了基于本体的语义检索系统的体系结构，该系统旨在实现对领域内资源的语义分析，赋予检索系统足够的语义信息。研究的重点是资源的元数据描述、领域本体的构建及语义查询，而这也是进行语义检索的理论基础。

Research and Design on Ontology-based Educational Resources

At present,the resources construction of our country is still short for sharing, reusing, resource retrieval’s recall ratio and precision ratio. To tackle issues like synonyms identifying and relevant searching difficulty in the current retrieval system, this paper leads the ontology in the construction of education resource and proposed the system structure of semantic retrieval system based on ontology. This system aims to to accomplish the semantic analysis in the field and and give adequate semantic infor-mation to the retrieval system. The focus point of the research is resource’s metadata annotations, the construction of domain on-tology and semantic query and this is the theoretical foundation to carry out semantic retrieval.
