Natural language processing methods (NLP) for Optum clinical data

From unstructured notes to insight and discovery

Manual review of unstructured data from electronic health records (EHRs) is typically impractical given the time commitment required. But the information contained in these data can often provide you with key information, ranging from characteristics of specific diagnoses to symptoms to patient risk behaviors.

Natural language processing (NLP) technology allows you to extract insights from free-text, de-identified EHR data. Optum curates EHR data using proprietary NLP systems to help you understand the progression of diseases with details often not available in structured formats.
