Cyc

Cyc (pronounced /ˈsaɪk/ SYKE) is a long-term artificial intelligence (AI) 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. The project began in July 1984 at MCC and was developed later by the Cycorp company... By 2002, Cyc was described as having "consumed $60 million and 600 person-years of effort from programmers, philosophers and others—collectively known as Cyclists—who have been codifying what Lenat calls 'consensus reality' and entering it into a massive database... The knowledge base is divided into microtheories. Unlike the knowledge base as a whole, each microtheory must be free from monotonic contradictions. Each microtheory is a first-class object in the Cyc ontology; it has a name that is a regular constant. The concept names in Cyc are CycL terms or constants... An inference engine is a computer program that tries to derive answers from a knowledge base. The Cyc inference engine performs general logical deduction.[9] It also performs inductive reasoning, statistical machine learning and symbolic machine learning, and abductive reasoning... A Semantic Web version of OpenCyc was available starting in 2008, but ending sometime after 2016... The Cyc project has been described as "one of the most controversial endeavors of the artificial intelligence history".[26] Catherine Havasi, CEO of Luminoso, says that Cyc is the predecessor project to IBM Watson.[27] Machine-learning scientist Pedro Domingos refers to the project as a "catastrophic failure" for the unending amount of data required to produce any viable results and the inability for Cyc to evolve on its own. https://en.wikipedia.org/wiki/Cyc
