Semantic Annotations and Context Reasoning to Enhance Knowledge Reuse in e-Learning

摘要

We address in this paper the need of improving knowledge reusability within online Communities of Practice of E-learning (CoPEs). Our approach is based on contextual semantic annotations. An ontological-based contextual semantic annotation model is presented. The model serves as the basis for implementing a context aware annotation system called "CoPEAnnot". Onto-logical and rule-based context reasoning contribute to improving knowledge reuse by adapting CoPEAnnot's search results, navigation and recommendation. The proposal has been experimented within a community of learners.
