Natural language processing systems for capturing and standardizing unstructured clinical information: A systematic review.

ABSTRACT: We followed a systematic approach based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses to identify existing clinical natural language processing (NLP) systems that generate structured information from unstructured free text. Seven literature databases were searched with a query combining the concepts of natural language processing and structured data capture.

These papers contained information about 71 different clinical NLP systems, which were then analyzed. The NLP syst
