On Implementing Usual Values

On Implementing Usual Values Ronald R. Yager Machine Intelligence Institute Iona College New Rochelle, N. Y. 10801 Abstract In many cases commonsense knowledge consists of knowledge of what is usual. In this paper we develop a system for reasoning with usual information. This system is based upon the fact that these pieces of commonsense information involve both a probabilistic aspect and a granular aspect. We implement this system with the aid of possibility-probability granules. Introduction An ability to handle commonsense reasoning is a crucial need in the development of the artificial intelligence [1].
