An Automatic Tool for the Analysis of Natural Language Requirements

The availability of automatic tools for the quality analysis of Natural Language requirements is recognized as a key factor for achieving software quality. Unfortunately, the state of the art and practice witnesses a lack of tools and techniques for the Natural Language requirements analysis. This paper presents a methodology and a tool (called QuARS - Quality Analyzer for Requirement Specifications), for analyzing Natural Language requirements in a systematic and automatic way. The QuARS tool allows the requirements engineers to perform an initial parsing of the requirements for automatically detecting potential linguistic defects that can determine ambiguity problems at the following development stages of the software product. This tool is also able to support automaticaaly the consistency and completeness analysis by clustering the requirements according to a specific topic.
