Semantic annotations and context reasoning to enhance knowledge reuse in e-learning

Abstract

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". Ontological 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. © Springer International Publishing Switzerland 2013.
