“Making Free Text Reports Available for Researchers via a De-identification and Natural Language Processing Pipeline”
Umit Topaloglu, PhD, FAMIA
Associate Professor, Wake Forest School of Medicine, Wake Forest University, Winston-Salem, NC
Abstract: With the recent advancements in predictive modeling and Machine Learning (ML) in healthcare, availability and accessibility of biomedical data provides an exciting opportunity for researchers. However, given majority of the clinical data is being unstructured, reproducible and scalable informatics tools that complies with regulations are needed. Dr. Topaloglu will present a set of tools that enables processing, de-identification, extraction of concepts and named entities, and deploying a search tool to provide researcher access and search notes prior to an IRB approval. These tools have been approved by the Privacy Board and the Compliance Office and implemented at Wake Forest Baptist Medical Center. Dr. Topaloglu will also discuss use cases for a newly developed specimen search tool for pathology and radiology reports. In addition, he will present an ML-based natural language processing implementations for specific data marts and potential improvements via federated learning paradigm.
When: Wednesday, March 31st 11:00 am – 12:00 pm
