bookmark BioCreative / Critical Assessment of Information Extraction systems in Biology Promote the development of biomedical text mining applications. BioCreative works closely with biocurators to understand the various curation workflows, the Text Mining (TM) tools that are being used and their major needs. One of the aims of the BioCreAtIvE challenge is to determine the state of the art for a given task in biomedical text mining. This can be achieved if a considerable number of participants from a given community participates and the provided results of each system is evaluated by domain experts using well defined evaluation metrics. To address the barriers in using TM in biocuration, BioCreative has been conducting user requirements analysis and user-based evaluations, and fostering standards development for TM tool re-use and integration.
