For a best collaboration between tutor and learner and relatively to discussion forum, the authors have proposed to tutor a semantic classification tool of messages, which helps him to manage the mass of messages accumulating during the time. The tool provides a semantic classification mechanism based on a chosen theme. For a classification more intelligent semantically, and focusing more the chosen theme, their tool incorporates essentially a formal OWL ontology. The reuse and interoperability offered by ontology remain restrictive in the tool's knowledge base.
