Online Presence in Adaptive Learning on the Social Semantic Web

In adaptive learning environments, this exchangeof online presence data cannot be considered isolatedfrom the overall learning context. However, there isyet no systematic solution to exchanging andintegrating online presence data from diverse instantmessaging and social networking applications. Toaddress this issue, we propose an ontology-basedapproach to sharing online presence data in adaptivelearning environments through the use of the OnlinePresence Ontology. This ontology is integrated into theLearning Object Context Ontology framework, whichallows for capturing and unambiguous representationof all relevant data about students online presence,their mutual interactions, as well as their interactionswith learning resources. On top of this ontologyframework, we have developed innovative, context-awarelearning services presented in this paper. Theuse of these services is demonstrated in a learningenvironment for studying software patterns.
