Frederick Hayes-Roth (born 1947) is an American computer scientist and educator. His principal work focuses on how to use computing processes to winnow data down to only those information items that are valuable to the receiver, using technology to deliver those items, and in designing IT systems structured for this task.


He was the Chief Technology Officer for Software at Hewlett-Packard from 2000-2001. Before that (1981-2000) he was Chairman and Chief Executive of two Silicon Valley companies which he co-founded. One was Teknowledge Corporation, founded with Edward Feigenbaum.[2]

He was the program director for research in Information Processing at the Rand Corporation from 1976-81. That research program was prolific and influential, leading to numerous systems and research paradigms, including the Opportunistic Model of Planning (one of the 10 most cited papers in Cognitive Science[citation needed]), the rule-based system ROSIE, a number of heuristic expert systems, Distributed Fleet Control, and methods for non-monotonic reasoning and learning in knowledge networks.

Prior to that (1976), was one of the co-inventors of the first continuous speech understanding systems, Hearsay-II,[3] which became the “blackboard architecture.” [4]

Hayes-Roth held faculty positions at MIT, Stanford, and Carnegie Mellon. In 2003 he became a professor in the Information Sciences Department at the United States Navy's Naval Postgraduate School (NPS) in Monterey, California. At NPS he has taught hundreds of mid-career leaders in DOD through his "capstone course" on IT Strategy and Policy at NPS. The focus of that course has been on ways to radically improve the success of DOD IT system efforts.[5]

Hayes-Roth's contributions have helped establish several methods and technologies now widespread in business and government for exploiting machine intelligence. Rule-based systems and expert systems routinely solve important problems and help organizations achieve higher levels of performance. His work on "Valued Information at the Right Time" (VIRT)[6] argues that "smart push" can increase communication efficiency by as much as five orders of magnitude. VIRT is used by the US Department of Defense and IT organizations such as Oracle.

Hayes-Roth promoted the idea of developing semantic models for information sharing based on their usefulness in end-to-end transactions. This approach has been pioneered in collaborative business areas such as electronics RosettaNet and mortgage processing MISMO. In the defense and security area, he has formulated a concept of "Rich Semantic Track" that would provide a standard formalized model of mobile entities with intention. Such a model would enable agencies to share information about aircraft or surface ships, for example, as well as their crews. In 2008, this work culminated in the release by the US Navy of the Maritime Information Exchange Model (MIEM).[7] The MIEM provides a semantic model, embodied in an XML schema, for tracking people, cargo, vessels, and facilities, as well as relationships among them including threats, anomalies, and other events. This research was featured in the National Research Laboratory (NRL) 2009 review.[1]

Through an interagency agreement, the MIEM became the maritime domain model within the National Information Exchange Model (NIEM). The NIEM is an interagency program led by DHS that provides information models to support collaborative sharing across federal, state, and local agencies.

Hayes-Roth is the originator of numerous patents, including patents on secure information exchange, change detection in web pages, and asynchronous phone communication.

In 2011, Hayes-Roth co-founded Truth Seal Corporation, a non-profit, in a response to the glut of information that makes it difficult to judge the veracity of information.[8] Truth Seal promotes truthfulness in public communications so that the general public uses credible information for judgments, decisions and actions. Truth Seal’s intent is that market incentives will increase the quantity of truthful information that all consumers and citizens need to process.[9]

Hayes-Roth has written more than 100 frequently-cited, published papers and authored or co-authored five other books, Building Expert Systems; Pattern-Directed Inference System; Radical Simplicity: Transforming Computers into Me-Centric Appliances; Hyper-Beings: How Intelligent Organizations Attain Supremacy through Information Superiority; and Truthiness Fever: How Lies and Propaganda are Poisoning Us and a Ten-Step Program for Recovery. He started a blog also known as Truthiness Fever.

He is a Fellow of the Association for the Advancement of Artificial Intelligence, which cited him as follows:

For leadership in commercialization of expert system technology; for the co-development of Hearsay II and opportunistic-planning; and for the technical management of ROSIE, M.1, S.1, and ABE.[10]

Hayes-Roth is also a Senior Member of the IEEE and a member of the Association for Computing Machinery.
