QuARS: Quality Analyzer for Requirement Specifications

The tool QuARS (Quality Analyzer for Requirement Specifications) is based on a quality model composed of a set of high-level quality properties for NL requirements to be evaluated by means of syntactic and structural indicators directly detectable and measurable looking at the sentences in requirement document. This quality model, even though not exhaustive, is sufficiently specific to include a significant part of the lexical and syntax-related issues of requirement documents. QuARS receives as input a text document and provides the user with the indication of those sentences of the document that, according to the quality model, have to be considered as defective.
