Michael John Witbrock is a computer scientist in the field of artificial intelligence. Witbrock is a native of New Zealand and is the former Vice President of Research at Cycorp, which is carrying out the Cyc project in an effort to produce a genuine Artificial Intelligence.
Background and Affiliations
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.
