基于语义网的教学资源内容包装信息模型研究

摘要

教学资源的开放共享需要形成有效的共享机制和成熟的模型技术框架。现有的学习技术标准为教学资源的共享提供了元数据标准，但在异构数据语义共享方面存在缺陷。分析了基于语义网的教学资源共享系统模型，改进了教学资源SCORM内容包装信息模型，针对学习资源的个性化推荐需求设计并实现了教学资源推荐功能，详细描述了语义网Web程序开发的一般过程和通用模块的实现。基于语义包装的资源检索方法在课程教学素材、参考资料的关联推荐完整度上比传统的资源检索方法有了较大的提高。%Open sharing of teaching resources relies on an effective mechanism of sharing and a mature model technology framework. Existed learning technology standards provide metadata for teaching resources sharing, but there have the deficiencies existing in the semantics share of heterogeneous data. This paper analyzes the teaching resource sharing system model based on semantic web,put forward the teaching resources of SCORM content packaging information model. Design and realize the recommendation function on demand of personal-ized recommendation of learning resources,give a detailed description of the semantic web application devel-opment process and the general module. Semantic packaging based resources retrieval method improves the in-tegrity in teaching material,reference recommendation comparing to the traditional retrieval method.
