Adapting a General Semantic Interpretation Approach to Biological Event Extraction

Halil Kilicoglu, Sabine Bergler

The second BioNLP Shared Task on Event Extraction (BioNLP-ST'11) follows up the previous shared task competition with a focus on generalization with respect to text types, event types and subject domains. In this spirit, we re-engineered and extended our event extraction system, emphasizing linguistic generalizations and avoiding domain-, event typeor text type-specific optimizations. Similar to our earlier system, syntactic dependencies form the basis of our approach. However, diverging from
more » ... at system's more pragmatic nature, we more clearly distinguish the shared task concerns from a general semantic composition scheme, that is based on the notion of embedding. We apply our methodology to core bio-event extraction and speculation/negation detection tasks in three main tracks. Our results demonstrate that such a general approach is viable and pinpoint some of its shortcomings.
