用OWL绑定学习对象元数据

Binding Learning Object Metadata with OWL

随着学习对象的增加,对学习对象的管理、查找、评价和共享需要通过元数据来实现。目前一般用XML或RDF绑定元数据。由于XML绑定缺乏语义性,RDF绑定虽然具有一定的语义性,但是其表达的语义不够。于是提出了用OWL绑定学习对象元数据,通过OWL提供的大量建模原语,可以为学习对象元数据增加更多的语义描述信息,从而更好地实现学习对象的语义查询。

Along with learning object increased, to manage, search, appraise and share learning object needs metadata. At present, the general method of binding learning object metadata is XML-binding or RDF-binding. Because of XML-binding lacks the semantics, and RDF-binding has some certain semantics, but its expression power of semantics is insufficient. A new method of binding learning object metadata with OWL is proposed. There are lots of modelling primitive constructors in OWL which can provide more semantic description information for learning object metadata. Through OWL-binding for learning object metadata, search learning object can be more efficiently.
