MCORES: a system for noun phrase coreference resolution for clinical records.

ABSTRACT:

Objective

Narratives of electronic medical records contain information that can be useful for clinical practice and multi-purpose research. This information needs to be put into a structured form before it can be used by automated systems. Coreference resolution is a step in the transformation of narratives into a structured form.

Methods

MCORES uses an enhanced set of lexical, syntactic, and semantic features. Some
