+# Dataset Card for n2c2 2011 Coreference
+
+## Dataset Description
+
+- **Homepage:** https://portal.dbmi.hms.harvard.edu/projects/n2c2-nlp/
+- **Pubmed:** False
+- **Public:** False
+- **Tasks:** Coreference Resolution
+
+
+The i2b2/VA corpus contained de-identified discharge summaries from Beth Israel
+Deaconess Medical Center, Partners Healthcare, and University of Pittsburgh Medical
+Center (UPMC). In addition, UPMC contributed de-identified progress notes to the
+i2b2/VA corpus. This dataset contains the records from Beth Israel and Partners.
+
+The i2b2/VA corpus contained five concept categories: problem, person, pronoun,
+test, and treatment. Each record in the i2b2/VA corpus was annotated by two
+independent annotators for coreference pairs. Then the pairs were post-processed
+in order to create coreference chains. These chains were presented to an adjudicator,
+who resolved the disagreements between the original annotations, and added or deleted
+annotations as necessary. The outputs of the adjudicators were then re-adjudicated, with
+particular attention being paid to duplicates and enforcing consistency in the annotations.
