A treatment of locative prepositional phrases is given thus illusttating the generation of the situation schemata and their interpretation in situation semantics. Introduction A natural language system aims to provide an overall framework for relating the linguistic form of utterances and thefr semantic interpretation. And the relation between the two must be algorithmic. In this paper we pursue an approach which is based on an algorithm for converting linguistic form to a format which we call a situation schema. A situation schema has a well-defined formal structure suggestive of logical form. This is a structure which is different from the standard model-theoretic one we will argue that it is a structure better adapted for the analysis of the meaning relation in natural languages. A situation schema is effectively calculable from the linguistic form and we believe that it provides a format usefull for further processing . in the construction of a natural language interface with a data system and also in connection with mechanical ữanslation systems. The general structure of situation schemata We begin by explaining the general structure of the situation schemata and how they are rooted in the situation semantics of Barwise and Perry Barwise and Perry 83 .
