Abstract: The present paper proposes a personalized recommendation approach of learning objects (LOs) within an online Community of Practice (CoP). Three strategies of recommendation have been proposed: (1) a semantic filtering (SemF) by member’s interests; (2) a collaborative filtering (CF) based on the member’s expertise level; and (3) a semantic collaborative filtering combining in different ways the two approaches. The expertise level of a member is calculated in relation to all of his domains of expertise using the domain knowledge ontology (DKOnto). A similarity measure is proposed based on a set of rules which cover all the possible cases for the relative positions of two domains in DKOnto. In order to illustrate our work, some preliminary results of experimentation have been presented.
