摘要：Creating situations that promote collaboration between learners and/or their tutor is generally based on traditional communication tools. These are an important means to exchange ideas among learners, validate and consolidate their learning. However, we note that the large volume of messages exchanged between students and the tutor generates unwanted noise that can cause problems of disorientation for the majority of learners and cognitive overload. Through a solution based on the use of annotations as a support for collaboration, we sought, first, to stimulate interaction and facilitate collaborative activities between learners and their tutor in an activity of understanding of a distance-learning course. Secondly, we have proposed to create connections, through automatic annotations, linking parts of the course to the most relevant messages posted in a discussion forum. The degree of relevance of these messages is based on a customized classification according to the profile of the learner and the objective of the course, as well as the integration of a semantic search done by applying a thesaurus to the LSA method.
