Fantechi A., Gnesi S., Lami G., Maccari A. Application of linguistic techniques for use case. Technical report, 2002.
The Use Case formalism is an effective way of capturing both Business Process and Functional System Requirements in a very simple and easy-to-learn way. Use Cases are mainly composed of Natural Language (NL)sentences. The use of NL as a way to specify the behavior of a system is however a critical point, due to the inherent ambiguity originating from different possible. We discuss the use of methods based on a linguistic approach, that analyze functional requirements expressed by means of textual (NL) Use Cases. The aim is to collect quality metrics and detect defects related to such inherent ambiguity. In a series of preliminary experiments, we applied a number of tools for quality evaluation of NL text to an industrial Use Cases document. We also discuss the application of linguistic analysis techniques to support semantic analysis of NL expressed Use Case.
