中文摘要 | 可重用性是学习对象不同于其他教学资源构件的重要特性,是其价值得以实现的重要条件,也是其成为学术界研究热点的重要原因之一;而本体由于其概念化、共享的本质特征,可以用于描述和表达学习对象,实现学习对象的共享与重用。本文采用文献分析方法,指出了只通过本体描述来丰富学习对象元数据的不足之处,提出以语义网的本体概念本身作为研究切入点,通过建立学习对象本体描述框架,对学习对象内容及结构进行本体描述,以实现学习对象中各成分的重用。 |
英文摘要 | The importance of learning objects (LOs) is often decided by its reusability, which makes LOs different from other learning resources, and to be focused in the field of current academia. Ontology has the characteristics of the conceptualization and sharability, and it can be used to annotate the LOs. Through literature review, this paper explains that enriching the metadata of LOs only through ontological description is not enough. Furthermore, based on the concept of ontology in semantic web, the paper proposes a framework to annotate LOs content as well as its structure in a hope to improve the reusability of LOs. |
