  Lexical resources such as WordNet and the EDR electronic dictionary have been
used in several NLP tasks. Probably, partly due to the fact that the EDR is not
freely available, WordNet has been used far more often than the EDR. We have
used both resources on the same task in order to make a comparison possible.
The task is automatic assignment of keywords to multi-party dialogue episodes
(i.e. thematically coherent stretches of spoken text). We show that the use of
lexical resources in such a task results in slightly higher performances than
the use of a purely statistically based method.
