Pestian Lab

  • Pestian Lab Research

    Our lab discovers how to teach computers to understand what neuro-psychiatric patients say. This research is often called natural language processing or computational linguistics. We do this by analyzing the free-text that we gather from the patients or large databases we developed over the years.

    We are currently collaborating on studies related to epilepsy, suicide, and emergency medicine. For epilepsy we are building computer systems that will be used by Cincinnati Children’s Hospital Medical Center, Colorado Children’s Hospital, and Children’s Hospital of Philadelphia to understand the quality of epilepsy care. For suicide, we are developing systems to identify the likelihood that a suicidal patient will have a repeated attempt.

  • Tools Developed by the Pestian Lab

    The following lists describe the software and data tools we have developed for research use. For more information on these tools, or on new tools we are developing, contact us at john.pestian@cchmc.org.

    Software Tools

    1. Encryption Broker – a tool that anonymizes and disambiguates clinical text without corrupting its meaning
    2. Christine – a tool for personalized medicine drug selection
    3. Christine Expert Opinion System – a tool for gathering expert opinions about personalized medicine drug selection
    4. Graphs of Consistent Concepts – a spreading activation graph system
    5. Radiology Negation System – an NLP system used for obtaining consensus on radiology negation data
    6. UMLS Visualizer – a tool that allows researchers to graphically see UMLS relationships

    Data Tools

    1. Pediatric Corpus – a collection of 600,000 words of HIPAA-anonymized clinical data approved for release by the Institutional Review Board of Cincinnati Children's
    2. Shared Task 2007 – a collection of clinical free text from radiology dictations
    3. Shared Task 2010 – a collection of approximately 1,000 suicide notes
