A framework of context-awareness support for peer recommendation in the e-learning context

For learners in distributed e-learning environments, it is difficult, but very important, to locate the right peer for collaboration on the right knowledge, at the right time and in the right way. This paper proposes the use of context awareness (CA) to support peer recommendation in the e-learning context. For this purpose, this paper explores the e-learning context that involves knowledge, social and technical contexts. Accordingly, this paper proposes a three-dimensional CA model for peer recommendation that includes CA to knowledge potential, social proximity and technical access. By matching the peer seeker and the peer candidate with respect to these three dimensions, the CA information is promising as an aid to the peer seeker in finding suitable knowledge collaborators. The importance of activity context is highlighted in CA-supported peer-recommendation mechanism. A five-dimensional (who, what, how, when and where) representation approach is suggested for activity-context description.
