Research Interests

  • Natural Language Processing

Dr. Patterson's research is focused on computational analysis of clinical narrative documents using natural language processing and machine learning for the purposes of cohort selection, phenotype extraction, outcomes prediction, and other health services research tasks. She has extensive experience working with a variety of clinical document types across a broad range of medical subdomains. She is an active co-investigator and collaborator on several research projects developing language processing software applications.

Research Statement

My primary research area is computational analysis of clinical text documents for the purposes of concept recognition, information extraction, information retrieval, and document classification. I have experience working with a number of various document types across clinical subdomains. I have developed a number of language processing systems to perform document clustering, document classification, word sense disambiguation, and clinical information extraction.
