BioNLP Shared Task 2011


The BioNLP Shared Task series represents a community-wide move in bio-textmining toward fine-grained information extraction (IE). The first event, the BioNLP 2009 shared task (Dec. 2008-March 2009), attracted wide attention, with 24 teams submitting final results. The task setup and data have since served as the basis of numerous studies and published event extraction systems and datasets. The BioNLP Shared Task 2011 (BioNLP-ST'11) is the follow-up event to the BioNLP 2009 shared task. While following the general outline and goals of the previous task in defining biologically relevant extraction targets and a linguistically motivated approach to event representation, the upcoming task will generalize and extend on the previous in three key aspects: text type, domain, and targeted event types. Manually annotated data where all annotations are bound to specific expressions in text will be provided for training, development and evaluation of extraction methods, and tools for detailed evaluation of system outputs will be made available. Participation to the task is open to all interested parties.

Sample data for each task is available and registration for the task is open from 14 Sep. 2010.
