We describe our approach for the extraction of drug-drug interactions from literature. The proposed method builds majority voting ensembles of contrasting machine learning methods, which exploit different linguistic feature spaces. We evaluated our approach in the context of the DDI Extraction 2011 challenge, where using document-wise crossvalidation, the best single classifier achieved an F1 of 57.3% and the best ensemble achieved 60.6%. On the held out test set, our best run achieved an F1 of 65.7%.
