摘要
协作学习是一种组学习方式,强调的是组成员之间的交流与合作,因此成员间的信息理解对协作的效率影响很大,本体论是概念化的明确表示和描述,因此本体可对学习资源进行语义标注。采用本体提供交流资源的统一语义描述,使学习者在语义基础上进行交流和查询,本体的引入保证了网络协作学习中知识理解和运用的一致性、精确性、不变性、可重用性和共享性。设计了基于本体的多主体网络协作学习模型,该模型不仅具有语义互操作性而且能有效支持知识的重用和共享,从而提高协作学习效率。
Collaborative learning is a kind of group learning mode. It emphasized the communication and collaboration among group members, so the information comprehension among group members influence collaborative efficiency. The ontology is a formal, explicit specification of a shared conceptualization, which represent domain knowledge and facilitate knowledge share. The uniform semantic description on which leaner can communicate and query is provided utilizeing ontology, the usage of the ontology guaranteed the consistency, accuracy, invariance, reusable and sharable of the knowledge comprehension and usage in network collaborative learning. The multi-agent web collaborative learning model based on Ontology is designed. This model has the characteristics of semantic interoperation and knowledge reusability to improve the collaborative learning efficiency.
