2018 n2c2 Shared-Task and Workshop

Announcement and Call for Participation


We are pleased to announce the 2018 n2c2 Shared Task on Challenges in Natural Language Processing for Clinical Data. This is the latest in a series that began in 2006 at the former i2b2 National Center for Biomedical Computing (NCBC) and now continues at the Harvard Medical School Department of Biomedical Informatics (DBMI) in partnership with the Volgenau School of Engineering of George Mason University.

The 2018 n2c2 Shared Task consists of two tracks:

  • Track 1: Cohort Selection for Clinical Trials
  • Track 2: Adverse Drug Events and Medication Extraction in EHRs

The two tracks will run in separate schedules but will be coordinated with respect to their dissemination efforts and the accompanying workshop. To receive updates as more information becomes available, please register for the n2c2 2018 challenge organizers Google Group .


The i2b2 Center (Informatics for Integrating Biology and the Bedside), funded by the National Institutes of Health (NIH) from 2004 to 2014 and based at Partners HealthCare System in Boston, was led by Principal Investigator Isaac Kohane, MD, PhD, and Executive Director Susanne Churchill, PhD. The i2b2 NLP Shared Task challenges/workshops and resulting research data sets were designed and led by Co-Investigator Ozlem Uzuner, MEng, PhD, originally at MIT CSAIL and subsequently at SUNY Albany.

Moving Forward

Drs. Kohane and Churchill are now the inaugural Chair and Executive Director, respectively, of DBMI, where the NLP Data Sets will remain under the stewardship of their Healthcare Data Science Program . The NLP Shared Task challenges and workshops continue to be directed by Dr. Uzuner , now Associate Professor of Information Sciences and Technology in the Volgenau School of Engineering at George Mason University.

The software development component of the former i2b2 Center is now under the direction of the i2b2 tranSMART Foundation , a member-driven non-profit foundation developing an open-source / open-data community around the i2b2, tranSMART and OpenBEL translational research platforms.
