Working Paper

The issue of how to represent the "meaning" of an utterance is central to the problem of computer understanding of natural language. Rather than relying on ad-hoc structures or forcing the complexities of natural language into mathematically elegant but computationally cumbersome representations (such as first-order logic), this paper presents a novel representation which has many desirable computational and logical properties. It is proposed to use this representation to structure the "world knowledge" of a natural-language understanding system.
