Structured Data Leads to Better Analysis, Outcomes

Scott Mace, for HealthLeaders Media, October 22, 2013

There's also a role for this kind of service in research. Many inclusion and exclusion criteria important to clinical trials are buried in physicians' notes. NLP could be used to identify these patients for use in study cohorts, Moore notes.

One other note: Although you might hear IBM describing NLP as an element of Watson, it is but one element of Watson. While Watson does employ NLP, it also contains a machine-learning element that helps Watson understand the entire ontology of a particular medical practice.

Over time, Watson "learns" more than it used to about a given practice, such as oncology. The NLP technology in use at UNCHC must be specifically programmed to seek and extract unstructured data into structured data, and as such, falls far short of Watson's ability to understand medicine.

Still, NLP is probably our best tool for mining unstructured data, and arrives none too soon given the explosion of electronically-stored medical data. And as Macko notes, "in the end, physicians are going to do what physicians do. They like to write things down, right?"
