Constructing Knowledge Representation Systems with First-Order Formulas as Atoms

Abstract

This paper proposes a knowledge representation system by extension of the concept of atom. Not only conventional simple atoms, but also atoms representing first-order formulas, which are called formula atoms, are used. By this extension, predicates, logical connectives, and quantifiers may occur in atoms, and can be regarded as objects in the same class, allowing more natural translation from natural language sentences into extended formulas and more flexible computation for solving logical problems. 
