Developing an Interface Ontology for AD Research Lead Investigator: Xubing Hao Institution : The University of Texas Health Science Center at H E-Mail : kathryn_gauthreaux@yahoo.com Proposal ID : 1644 Proposal Description: Our aim is to develop an interface ontology and model a comprehensive collection of AD-related biomedical concepts. This will enable faceted web interfaces for data exploration and cohort discovery. We will enrich concepts and concept type and properties in our ontology based on NACC datasets. We will develop a natural language processing algorithm to select data elements in NACC data that involve concepts that are not covered by our ontology yet.
