Announcement of Data Release and Call for Participation
2012 i2b2 Shared-Tasks and Workshop
on Challenges in Natural Language Processing for Clinical Data
Training Data Release: 1 June, 2012
Test Data Release: 1 August, 2012
System Outputs Due: 3 August, 2012
Paper Submission: 1 September, 2012
Workshop: November, 2012 with AMIA
The 2012 i2b2 challenge is on temporal relations. The data for this task is provided by Partners HealthCare and the Beth Israel Deaconess Medical Center (MIMIC II Database). All records have been fully de-identified and manually annotated for temporal relations.
The challenge registration starts on April 14, 2012. Training data for the challenge will be released starting June 1, 2012. Test data are scheduled to be released in August 2012. The results of the challenge will be presented at the workshop organized by i2b2 at AMIA.
Data for the task will be released under a Data Use Agreement and are to be used for research only. Obtaining the data requires completing a registration and signing the Data Use Agreement.
Evaluation Dates, File Formats, and Evaluation Metrics.
The evaluation will be conducted 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 (through this website) 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 to be provided by the organizers.
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.
