Building large knowledge-based systems: Representation and inference in the cyc project: D.B. Lenat and R.V. Guha

摘要

The book under review here, Building Large Knowledge-Based Systems: Representation and Inference in the Cyc Project, describes progress so far in an attempt to build a system that is intended to exhibit general common-sense reasoning ability. This review first discusses aspects of the Cyc system, with a focus on important decisions made in designing its knowledge representation language, and on how claims about the performance of the system might be validated.‡ The review then turns to the book itself, discussing both its merits and its faults.
