Verifying natural language processing in health care

Abstract:

A computer system visualizes medical information for a patient. Natural language processing techniques are applied to identify medical concepts within unstructured text of medical information. Values for the identified medical concepts are derived from combinations of values within the medical information. A visualization is generated for a selected derived value, wherein the visualization includes a plurality of interconnected nodes each associated with a corresponding information source utilized for determining the selected derived value, and wherein paths of the interconnected nodes in the visualization indicate the corresponding information sources utilized to produce the selected derived value. Information of a selected node of the visualization is updated based on user verification of the information of the selected node. The visualization is modified based on the updated information. Embodiments of the present invention further include a method and program product for visualizing medical information for a patient in substantially the same manner described above.
