Title
NADE - A Benchmark for Robust Adverse Drug Events Extraction in Face of Negations.
Abstract
Adverse Drug Event (ADE) extraction mod-els can rapidly examine large collections of so-cial media texts, detecting mentions of drug-related adverse reactions and trigger medicalinvestigations. However, despite the recent ad-vances in NLP, it is currently unknown if suchmodels are robust in face ofnegation, which ispervasive across language varieties.In this paper we evaluate three state-of-the-artsystems, showing their fragility against nega-tion, and then we introduce two possible strate-gies to increase the robustness of these mod-els: a pipeline approach, relying on a specificcomponent for negation detection; an augmen-tation of an ADE extraction dataset to artifi-cially create negated samples and further trainthe models.We show that both strategies bring significantincreases in performance, lowering the num-ber of spurious entities predicted by the mod-els. Our dataset and code will be publicly re-leased to encourage research on the topic.
