Benjamin Grosof

Benjamin Grosof (Chief Scientist, Co-founder) is an industry leader in knowledge representation, reasoning, and acquisition. He has pioneered semantic technology and industry standards for rules combined with ontologies, their acquisition from natural language (NL), and their applications in finance, e-commerce, policies (including contracts, regulations, and security), and e-learning. He co-founded the influential standards design body RuleML and has had driving roles in W3C RIF (Rule Interchange Format) and W3C OWL-RL (rule-based ontologies). He led the invention of several fundamental technical advances in knowledge representation including Rulelog (a major research breakthrough in logic-based artificial intelligence combined with natural language processing), courteous defeasibility (exception-case rules), restraint bounded rationality (scalability in complex reasoning), and rule-based description-logic ontologies. He has extensive experience in user interaction design, and in combining logical methods with machine learning and probabilistic uncertainty.
