Lisa Dawn Colvin has been developing large-scale ontologies and semantic-based applications for over 15 years. At TopQuadrant, she developed data architecture standards for naming, identification and metadata for the NASA Constellation Program. Prior to TopQuadrant, she provided knowledge applications services for Genentech, fought spam at Inktomi / Yahoo!, and was Product Manager for VerticalNet’s Ontology Builder. Her interest in ontologies began with her work as a computational linguist on the first attempt to formalize common-sense knowledge in a multi-contextual knowledge base, the CYC project at Cycorp. She received her M.S. in Technology Commercialization from University of Texas at Austin, an M.A. in Linguistics also from UT-Austin, and a B.A. in Philosophy from Tufts University.
