CLaC Labs: Processing Modality and Negation. Working Notes for QA4MRE Pilot Task at CLEF 2012.
Sabine Rosenberg, Halil Kilicoglu, Sabine Bergler · 2012
For the QA4MRE 2012 Pilot Task on Negation and Modality, CLaC Labs implemented a general, lightweight negation and modality module based on linguistic rules. The strong results confirm the suitability of linguistic heuristics for low-level semantic features and showcase their robustness across the different subgenres of the QA4MRE corpora.
