The extraction of bio-molecular events from text is an important task for a number of domain applications such as pathway construction. Several syntactic parsers have been used in Biomedical Natural Language Processing (BioNLP) applica- tions, and the BioNLP 2009 Shared Task results suggest that incorporation of syn- tactic analysis is important to achieving state-of-the-art performance. Direct com- parison of parsers is complicated by to dif- ferences in the such as the division be- tween phrase structure- and dependency- based analyses and the variety of output formats, structures and representations ap- plied. In this paper, we present a task- oriented comparison of five parsers, mea- suring their contribution to bio-molecular event extraction using a state-of-the-art event extraction s...
