BioCreAtIvE (A critical assessment of text mining methods in molecular biology) consists in a community-wide effort for evaluating information extraction and text mining developments in the biological domain.
Three main tasks were posed at the first BioCreAtIvE challenge: the entity extraction task, the gene name normalization task, and the functional annotation of gene products task. The data sets produced by this contest serve as a Gold Standard training and test set to evaluate and train Bio-NER tools and annotation extraction tools.
The second BioCreAtIvE included three tasks organized by Lynette Hirschman and Alex Morgan of MITRE; Alfonso Valencia and Martin Krallinger of CNIO in Spain; and W. John Wilbur, Lorrie Tanabe and Larry Smith of NIH.
