IRIT at CheckThat! 2018
Résumé
The 2018 CLEF CheckThat! is composed of two tasks: (1) Check-Worthiness and (2) Factuality. We participated to task (1) only which purpose is to evaluate the check-worthiness of claims in political debates. Our method to achieve this goal is to represent each claim by a vector of five computed values that correspond to scores on five criteria. These vectors are then used with machine learning algorithms to classify claims as check-worthy or not. We submitted three runs using different machine learning algorithms. The best result we achieved using the offi-cial measure MAP ranks our primary run the 12th over the 16 submitted runs. Our first contrastive run is ranked 2nd with the Mean Precision@1 measure.
