Data Release: 15 April, 2010 Evaluation: 15-18 July, 2010 Paper Submission: 1 September, 2010 Workshop: November, 2010 in Washington, DC
The fourth i2b2/VA challenge is a three tiered challenge that studies: - extraction of medical problems, tests, and treatments - classification of assertions made on medical problems - relations of medical problems, tests, and treatments
The data for this challenge includes discharge summaries from Partners Healthcare and from Beth Israel Deaconess Medical Center, as well as discharge summaries and progress notes from University of Pittsburgh Medical Center. All records have been fully de-identified and manually annotated for concept, assertion, and relation information. Participants of the Fourth i2b2/VA Challenge can choose to tackle any or all of the tasks in any of the tiers.
The challenge registration starts on March 15, 2010 through https://i2b2.org/NLP. Training data for the challenge will be released in installments starting April 15, 2010. Test data are scheduled to be released in July 2010. The results of the challenge will be presented at the workshop organized by i2b2 and VA.
Data for the Fourth i2b2/VA Challenge will be released under a Data Use Agreement and are to be used for research only. Obtaining the data requires completing a registration through i2b2.org/NLP and signing the Data Use Agreement.
Evaluation Dates, File Formats, and Evaluation Metrics.
The Fourth i2b2/VA Challenge evaluation will be done using withheld test data. Participating teams are asked to stop development as soon as they download the test data. Each team is allowed to upload up to three system runs for each of the tiers of the challenge. System output is expected in the form of standoff annotations, following the exact format of the ground truth annotations provided by the organizers. Precision, recall, and f-measure will be used as evaluation metrics.
Participants are asked to submit a short paper describing their system and analyzing their performance. Papers should be in AMIA style and should not exceed five pages. Authors of top performing systems and of particularly novel approaches will be invited to present or demo their systems at the workshop.
