Grand rounds: Development and Validation of Natural Language Processing Algorithms in the National ENACT Network

Director of the Clinical Natural Language Processing and Artificial Intelligence Innovation Laboratory at the University of Pittsburgh, Yanshan Wang, will discuss, “Development and validation of Natural Language Processing algorithms in the national ENACT Network.”

Wang will discuss:

• The ENACT NLP Working Group. The group is developing methods to extract clinical concepts from narrative notes for deployment in the ENACT Network.
• The ENACT NLP Working Group, established with 13 sites, developed and validated NLP algorithms for rare disease phenotyping, social determinants of health, opioid use disorder, sleep phenotyping, and delirium phenotyping. The group achieved 100% site retention, deployed NLP infrastructure, and extended the ENACT ontology to standardize NLP-derived data. This work demonstrates the feasibility of deploying NLP infrastructure across large, federated networks.
