An Introduction to the CYC Knowledge Base Essay -- CYC Project Technol

An Introduction to the CYC association BaseI. AbstractThis paper is intended to be an introductory tutorial on the Very Large Knowledge Base (VLKB) called CYC. Described herein is the reasoning for the origination of the CYC project, the intended usefulness of the project (application areas), how CYC is be constructed, and a brief introduction to the supporting tools that have been developed to interact with the CYC companionship base.II. IntroductionMany Knowledge Bases (KB) have been developed to help quite a little solve problems in very specific applications. These are relatively honest to build since the knowledge required by the specific system ingest to be only those facts required to solve the problem in that crabbed proposition application. An example of this type of KB would be one that contains only the education needed to diagnose particular fungal and bacterial infections. The KB would need to know about the different attri exactlyes of the microscopic organisms and their affects on the host but would not need to know that the grass is green or that the priming revolves around the sun.The CYC super acid sense Knowledge Base takes the opposite approach. CYC is being created to hold information that most people would consider to be common sense knowledge. The idea is to create a KB that would supply the fundamental knowledge needed to be applicable to many different applications. By building a KB with this general knowledge, it is hoped that the KB will be able to learn (create new inferences) by itself and be able to express when it does not have enough information in a particular domain to resolve a problem.The CYC project was started by Doug Lenat at MCC (Microelectronics and computing device Technology Corporation, now Cycorp, Inc.) in Aust... ...nology, Cycorp, Inc, http//www.cyc.comGinsberg, Matthew L., Essentials of Artificial Intelligence.
