The results exposed in this article only concern the analyzer. The evaluation is based
on the MEDIA corpus which is the French reference dialog corpus with evaluation
tools. The linguistic model that we implement, which is a kind of context-free grammar,
is pretty simple. Since the scores we obtain are equivalent to those of other systems, this
proves that this approach is good enough in our dialog context.
