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

An Introduction to the CYC Knowledge showI. AbstractThis paper is intended to be an introductory tutorial on the Very Large Knowledge can (VLKB) called CYC. Described herein is the reasoning for the origination of the CYC ascertain, the intended usefulness of the project (application argonas), how CYC is being constructed, and a brief introduction to the supporting tools that have been create to interact with the CYC knowledge base.II. IntroductionMany Knowledge Bases (KB) have been authentic to help people solve worrys in very particular(prenominal) applications. These are relatively simple to build since the knowledge required by the specific system needs to be only those facts required to solve the problem in that particular application. An example of this type of KB would be angiotensin converting enzyme that contains only the information needed to diagnose particular fungal and bacterial infections. The KB would need to know about the different attributes of the microsco pic organisms and their affects on the host but would not need to know that the grass is cat valium or that the earth revolves around the sun.The CYC common sense Knowledge Base takes the opposite approach. CYC is being created to hold information that most people would turn over to be common sense knowledge. The idea is to create a KB that would supply the basic knowledge needed to be applicable to more 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 tell 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 Computer Technology Corporation, now Cycorp, Inc.) in Aust... ...nology, Cycorp, Inc, http//www.cyc.comGinsberg, Matthew L., Essentials of Artificial Intelligence.
