Informatics for Integrating Biology and the Bedside, i2b2, a National 
Center for Biomedical Computing, is ready to release fully de-identified 
discharge records for its Second shared task!

In collaboration with State University of New York at Albany, MIT Computer 
Science and Artificial Intelligence Laboratory, and Partners Healthcare 
System, i2b2 is pleased to announce the Second Shared Task and Workshop on 
Challenges in Natural Language Processing for Clinical Data.

The Second i2b2 Shared Task on Challenges in Natural Language Processing 
for Clinical Data opens to preregistration on February 1, 2008. The 2008 
Challenge is a multi-class, multi-label classification task focused on 
obesity and its co-morbidities. The data for the challenge consists of 
discharge summaries from Partners Healthcare. All records have been fully 
de-identified and annotated for obesity and co-morbidities.

Training data for the 2008 Challenge will be released in installments; 
first installment will be released on March 15, 2008. The rest of the 
installments will follow soon after. Test data is scheduled to be 
released, for only three days, and will be used for only evaluation 
purposes. The results of the shared-task challenge will be presented at 
the workshop organized by i2b2 (Date and location are TBA).

Data will be released under a Data Use Agreement and is to be used for the 
Challenge only. Obtaining the data requires completing a preregistration 
and singing the Data Use Agreement. All members of a team are requested to 
sign the Data Use Agreement.
