Michael Witbrock

Dr. Witbrock was born in Christchurch, New Zealand, and has a Ph.D. in computer science from Carnegie Mellon University. Before joining Cycorp, he was a principal scientist at Terra Lycos, working on integrating statistical and knowledge-based approaches to understanding Web user behavior; he has also been associated with Just Systems Pittsburgh Research Center and the Informedia Digital Library at Carnegie Mellon.

Dr. Witbrock's dissertation work was on speaker modeling; before going to Cycorp, he published in a broad range of areas, including:

• Neural networks
• Multimedia information retrieval
• Genetic design
• Computational linguistics
• Speech recognition
• Web-browser design

His work at Cycorp has focused on improving its knowledge formation efforts, particularly dialogue processing, and on improving accessibility to the Cyc project.
