Event extraction is a major focus of re- cent work in biomedical information extrac- tion. Despite substantial advances, many chal- lenges still remain for reliable automatic ex- traction of events from text. We introduce a new biomedical event extraction resource con- sisting of analyses automatically created by systems participating in the recent BioNLP Shared Task (ST) 2011. In providing for the first time the outputs of a broad set of state-of- the-art event extraction systems, this resource opens many new opportunities for studying aspects of event extraction, from the identifi- cation of common errors to the study of ef- fective approaches to combining the strengths of systems. We demonstrate these opportuni- ties through a multi-system analysis on three BioNLP ST 2011 main tasks, fo...
