Thomas Robert 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. [1] [2]
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. [3]
From 1988 to 1994 Gruber was a research associate at the Knowledge Systems Laboratory of the Computer Science Department at Stanford University. He worked on the How Things Work, SHADE, and Knowledge Sharing Technology projects. In 1994 he became Senior Project Leader, Enterprise Integration Technologies and proposed and designed several projects using the Internet to create shared, virtual environments for collaborative learning and work (for ARPA, NASA, and NIST). During this time, he also proposed a business plan for corporate training. In 1995, he founded and became Chief Technology Officer of Intraspect Software, [3] an enterprise software company that did early commercial work on collaborative knowledge management. Intraspect applications help professional people collaborate in large distributed communities, continuously contributing to a collective body of knowledge. [1]
Gruber has been a member of journal editorial boards of the "Knowledge Acquisition", "IEEE Expert" and "International Journal of Human-Computer Studies".
Gruber's research interests in the 1990s were in the field of developing intelligent networked software to support human collaboration and learning. Areas of specialty include knowledge acquisition, knowledge representation, computer-supported collaborative work, computer-mediated communication for design, and knowledge sharing technology. [3]
In 1994 he was responsible for the creation of hypermail, an email to web gateway software that saw extensive use after a rewrite by a different programmer.
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. In 2016, Siri was added to macOS in macOS Sierra.
In April 2017 Gruber spoke on the TED stage about his vision for the future of "humanistic AI" especially in regard to augmentation of human capacities such as memory. [4] He is quoted saying, "We are in the middle of a renaissance in AI. Every time a machine gets smarter, we get smarter."
Gruber published several articles and some books, [5] most notably:
Cyc is a long-term artificial intelligence project that aims to assemble a comprehensive ontology and knowledge base that spans the basic concepts and rules about how the world works. Hoping to capture common sense knowledge, Cyc focuses on implicit knowledge that other AI platforms may take for granted. This is contrasted with facts one might find somewhere on the internet or retrieve via a search engine or Wikipedia. Cyc enables semantic reasoners to perform human-like reasoning and be less "brittle" when confronted with novel situations.
Knowledge representation and reasoning is the field of artificial intelligence (AI) dedicated to representing information about the world in a form that a computer system can use to solve complex tasks such as diagnosing a medical condition or having a dialog in a natural language. Knowledge representation incorporates findings from psychology about how humans solve problems and represent knowledge in order to design formalisms that will make complex systems easier to design and build. Knowledge representation and reasoning also incorporates findings from logic to automate various kinds of reasoning, such as the application of rules or the relations of sets and subsets.
In information science, an ontology encompasses a representation, formal naming, and definitions of the categories, properties, and relations between the concepts, data, or entities that pertain to one, many, or all domains of discourse. More simply, an ontology is a way of showing the properties of a subject area and how they are related, by defining a set of terms and relational expressions that represent the entities in that subject area. The field which studies ontologies so conceived is sometimes referred to as applied ontology.

Dabbala Rajagopal "Raj" Reddy is an Indian-born American computer scientist and a winner of the Turing Award. He is one of the early pioneers of artificial intelligence and has served on the faculty of Stanford and Carnegie Mellon for over 50 years. He was the founding director of the Robotics Institute at Carnegie Mellon University. He was instrumental in helping to create Rajiv Gandhi University of Knowledge Technologies in India, to cater to the educational needs of the low-income, gifted, rural youth. He is the chairman of International Institute of Information Technology, Hyderabad. He is the first person of Asian origin to receive the Turing Award, in 1994, known as the Nobel Prize of Computer Science, for his work in the field of artificial intelligence.
Legal informatics is an area within information science.
Knowledge-based engineering (KBE) is the application of knowledge-based systems technology to the domain of manufacturing design and production. The design process is inherently a knowledge-intensive activity, so a great deal of the emphasis for KBE is on the use of knowledge-based technology to support computer-aided design (CAD) however knowledge-based techniques can be applied to the entire product lifecycle.

Natural-language user interface is a type of computer human interface where linguistic phenomena such as verbs, phrases and clauses act as UI controls for creating, selecting and modifying data in software applications.
A virtual assistant (VA) is a software agent that can perform a range of tasks or services for a user based on user input such as commands or questions, including verbal ones. Such technologies often incorporate chatbot capabilities to simulate human conversation, such as via online chat, to facilitate interaction with their users. The interaction may be via text, graphical interface, or voice - as some virtual assistants are able to interpret human speech and respond via synthesized voices.
Dr. Robert L. Simpson Jr. is a computer scientist whose primary research interest is applied artificial intelligence. He served as Chief Scientist at Applied Systems Intelligence, Inc. (ASI) working with Dr. Norman D. Geddes, CEO. Dr. Simpson was responsible for the creation of the ASI core technology PreAct. ASI has since changed its name to Veloxiti Inc.
Knowledge-based configuration, also referred to as product configuration or product customization, is an activity of customising a product to meet the needs of a particular customer. The product in question may consist of mechanical parts, services, and software. Knowledge-based configuration is a major application area for artificial intelligence (AI), and it is based on modelling of the configurations in a manner that allows the utilisation of AI techniques for searching for a valid configuration to meet the needs of a particular customer.

He is a Fellow of the Royal Society of Edinburgh (1992), the British Computer Society (1995), and the European AI Society (2004).
Knowledge acquisition is the process used to define the rules and ontologies required for a knowledge-based system. The phrase was first used in conjunction with expert systems to describe the initial tasks associated with developing an expert system, namely finding and interviewing domain experts and capturing their knowledge via rules, objects, and frame-based ontologies.
