Programmatic access to the open source version of the Cyc Knowledge Base, the world's largest and most complete general knowledge base and commonsense reasoning engine. The Cyc Knowledge Base is a formalized representation of a vast quantity of fundamental human knowledge: facts, rules of thumb, and heuristics for reasoning about the objects and events of everyday life. OpenCyc includes the Cyc ontology, which contains hundreds of thousands of terms, plus millions of assertions relating the terms to each other, forming an upper ontology whose domain is all of human consensus reality. Returns results in XML.
