Tom Gruber

Thomas Robert "Tom" Gruber (born 1959) is an American computer scientist, inventor, and entrepreneur with a focus on systems for knowledge sharing and collective intelligence. He did foundational work in ontology engineering and is well known for his definition of ontologies in the context of artificial intelligence.

In 2007 Gruber co-founded Siri Inc., which created the Siri intelligent personal assistant and knowledge navigator. Siri Inc. was acquired by Apple in 2010, and Siri is now an integral part of iOS.

Gruber studied psychology and computer science at the Loyola University New Orleans, where he received a double major B.S. in 1981 and graduated summa cum laude. He designed and implemented a computer-assisted instruction (CAI) system for programmed-curriculum courses. It was the first of its kind at the university, and is used routinely by the Psychology department for introductory courses. In 1984 he received a M.S. in Computer and Information Science at the University of Massachusetts Amherst. For his Master's research, Gruber designed and implemented an intelligent communication prosthesis assistant, a computer system which enables people with severe physical disabilities who cannot otherwise speak to communicate in natural language presented in displayed, written, or spoken form. Four years later in 1988 at the University of Massachusetts Amherst he received a Ph.D. in Computer and Information Science with the dissertation "The Acquisition of Strategic Knowledge". His dissertation research addressed a critical problem for Artificial Intelligence—knowledge acquisition—with a computer assistant that acquires strategic knowledge from experts.
