This work considers the relevance in documents retrieval on the Web can be important to encourage collaborative learning dynamics based on discussion. To improve and contextualize the documents retrieval on the Web, this paper proposes: (i) the context modeling from the extraction of messages in social networking groups and (ii) use of the context to improve the relevance in the documents retrieval on the Web.
