OpenCyc

OpenCyc bilgisayarların insan gibi akıl yürütebilmeleri için YZ uygulamalarına veri sağlama amacı ile, gündelik sağduyu (common-sense) bilgisi sağlamaya çalışan kapsamlı bir ontoloji ve veritabanı oluşturmayı hedefleyen açık kaynak kodlu bir yapay zeka projesi.

The project was started in 1984 by Doug Lenat as part of Microelectronics and Computer Technology Corporation. The name "Cyc" (from "encyclopedia", pronounced like psych) is a registered trademark owned by Cycorp, Inc. in Austin, Texas, a company run by Lenat and devoted to the development of Cyc. The original knowledge base is proprietary, but a smaller version of the knowledge base has been released as OpenCyc under an open source license.

Typical pieces of knowledge represented in the database are "Every tree is a plant" and "Plants die eventually". When asked whether trees die, the inference engine can draw the obvious conclusion and answers the question correctly. The Knowledge Base (KB) contains over a million human-defined assertions, rules or common sense ideas. These are formulated in the language CycL, which is based on predicate calculus and has a syntax similar to that of the Lisp programming language. CycL users pun that they are "cyclists".

Much of the current work on the Cyc project continues to be knowledge engineering, representing facts about the world by hand, and implementing efficient inference mechanisms on that knowledge. Increasingly, however, the thrust of work at Cycorp involves giving the Cyc system the ability to communicate with end users in natural language, and to assist with the knowledge formation process.
