Abstract

This article extends a framework intended to simplify the generation of use cases. The framework allows a concrete and systematic way of describing actions by means of a use case pattern and simple natural language sentences. The framework is composed of a pattern for specifying a use case and a set of guidelines for writing the sentences describing it. These guidelines help the specifier to write natural language sentences that may be easy and uniformly understood. The extension presented in this article uses situation theory to formalise the use cases as situations and to translate the simple sentences into situation theoretic concepts. This article refers to PROSIT, a computational implementation of situation theory, to show how use cases can be described in terms of situation theory.
