Challenges in Natural Language Processing for Clinical Data
Medication Extraction Challenge
Data Release: 1 June, 2009
Evaluation: 17 August, 2009 (9:00am EST) to 19 August, 2009 (11:59pm EST)
Workshop: 13 November, 2009 in San Francisco, CA
Organizer: Informatics for Integrating Biology and the Bedside, i2b2, a National Center for Biomedical Computing
Medication extraction challenge aims to encourage development of natural language processing systems for the extraction of medication-related information from narrative patient records. Information to be targeted includes medications, dosages, modes of administration, frequency of administration, and the reason for administration. In order to encourage the development of semi- and un-supervised systems for medication extraction, the development data for the medication extraction challenge will be distributed unannotated. Participants will be allowed to create their own annotations. For this purpose, annotation guidelines and sample annotated records will be provided.
