چکیده
Terminological acquisition for identifying keywords of scientific articles The challenge DEFT2012 aims at automatically identifying the keywords chosen by the authors of scientific articles in the Humanities. A keyword list is provided within the track 1. We propose to exploit terminological acquisition approaches. The extracted terms are also sorted and filtered according to their position in the documents, weighting measures and linguistic criteria. We defined several configurations of our system. Our best F-measure for the track 1 is 0.3985 while for the track 2, the best F-measure is 0.1921. MOTS-CLÉS : Mots clés, extraction de termes, mesure de pondération, filtrage de termes.
