An Introduction to the Syntax and Content of Cyc i

Abstract

From the beginning, a primary goal of the Cyc project has been to build a large knowledge base containing a store of formalized background knowledge suitable for supporting reasoning in a variety of domains. In this paper, we will discuss the portion of Cyc technology that has been released in open source form as OpenCyc, provide examples of the content available in ResearchCyc, and discuss their utility for the future development of fully formalized knowledge bases.
