Higher-order computational logic

Abstract

This paper presents a case for the use of higher-order logic as a foundation for computational logic. A suitable polymorphically-typed, higher-order logic is introduced and its syntax and proof theory briefly described. In addition, a metric space of closed terms suitable for knowledge representation purposes is presented. The approach to representing individuals is illustrated with some examples, as is the technique of programming with abstractions. The paper concludes by placing the results in the wider context of previous and current research in the use of higherorder logic in computational logic. Show more
