The freetext matching algorithm: a computer program to extract diagnoses and causes of death from unstructured text in electronic health records

Anoop D Shah, Carlos Martinez, Harry Hemingway
2012 BMC Medical Informatics and Decision Making  
We present a platform that combines an approach to semantic extraction of medical information from clinical free-text documents with the processing of structured information from HIS records.  ...  The information extraction process uses a fine-grained linguistic analysis, and maps preprocessed terms to the concepts of domain-specific ontologies.  ...  CDR clients are data-source adapters for storage of structured data or raw clinical texts, enrichment algorithms that produce semantically enriched facts.  ...
