Michael Uschold is a Senior Ontology Consultant at Semantic Arts, Inc.. He possess expertise in ontologies, semantic web, semantic technologies, artificial intelligence, software development and 25 more skills. Colleagues describe him as "I have been very impressed by Michael's ability to critically and constructively review technical documents. His most heroic effort in this regard was reviewing my own book (Semantic Web for the Working Ontologist). He reviewed every chapter sometimes more than once, commented on just about every paragraph, and worked through all the examples. Michael worked hard to help us make this book the best it could be. We agreed with the vast majority of his suggestions, which significantly improved the quality of the material. Even those we didn't agree with were so thoughtful that they also contributed greatly to the quality of the final product. Our first priority in writing the book's acknowledgments was to recognize the heroic effort he put into the manuscript. Michael is well respected for his reviews of technical papers. There are reviews, there are great reviews, and then there are Uschold reviews. Whenever I face a difficult challenge in handling multiple conflicting reviews for a paper, I can always count on Michael to sift through and understand the tangled web of issues and opinions and clearly summarize the results. This makes it much easier to make a good decision." and "I strongly recommend Mike for any ontology related position. He has made world-class primary contributions to ontology engineering, helping to make it a sound technical discipline in computer science. I knew of Mike before I knew him, due to his trail-blazing efforts with the enterprise ontology at U. Edinburgh and his very early AAAI tutorials with Michael Gruninger of U. Toronto. When Mike came to Boeing in about 1997 (he was on the west coast, I was on the east coast), I marveled at how Boeing had managed to hire someone with his great status and knowledge of ontology engineering -- and welcomed the great event. Subsequently, Mike and I have interacted substantially over the years, joining together to give a tutorial at SemTech 2007 on semantics and ontologies, among other collaborations. Mike is an extremely sound computer scientist, ontologist, and a very pragmatic engineer, who truly seeks to ensure that semantic technologies and ontology engineering provide good value to users."
