QuARS versus QuARS Express
Trentanni G.
QuARS and QuARS Express (Quality Analyzer of Requirements Specifications) are tools that make it easier to extract structured information and metrics for detecting linguistic inaccuracies and defects in software requirements expressed in Natural language. The Express edition of QuARS represent a parallel evolution of the main tool exploiting the same core engine for an increased usability and a more expressive set of reports. In this article a comparison is presented.Source: ISTI Technical reports, 2011

QuARS: Quality Analyzer for Requirement Specifications
Fabbrini F., Fusani M., Gnesi S., Lami G., Trentanni G.
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.

Quality analysis of NL requirements: an industrial case study
Bucchiarone A., Gnesi S.
Nowadays common practice indicates that the Requirement Engineering (RE) process critically influences the success of the system development life cycle. Several commercial tools allow to classify, archive and manage requirements and then to print out reports and requirement documents. QuARS (Quality Analyzer for Requirements Specifications) is an automatic analyzer of such requirement documents, developed by ISTI - CNR, that can be adopted to evaluate the document quality by linguistic point of view. In this paper is presented how a requirement management tool, an automatic document generator and QuARS can be integrated to define an RE automation support. The case study investigates and highlights the efficacy and the role of such proposed support in the Siemens C.N.X. development process.Source: 13th IEEE International Requirements Engineering Conference (RE05), pp. 390–394, Paris, August 29 - September 2 2005

An Automatic Tool for the Analysis of Natural Language Requirements
Lami G., Gnesi S., Trentanni G., Fabbrini F., Fusani M.
Using automatic tools for the quality analysis of Natural Language (NL) requirements is recognized as a key factor for achieving software quality. Unfortunately few tools and techniques for the NL requirements analysis are currently available. This paper presents a methodology and a tool (called QuARS - Quality Analyzer for Requirement Specifications) for analyzing NL requirements in a systematic and automatic way. QuARS allows requirements engineers to perform an initial parsing of the requirements in order to automatically detect potential linguistic defects that could cause interpretation problems at subsequent stages in developing the software. This tool is also able to partially support the consistency and completeness analysis by clustering the requirements according to specific topics.Source: Computer systems science and engineering 20 (2005): 53–62.

Applying the QARS tool to detect variability
Fantechi A., Gnesi S., Semini L.
In this demo paper we present how to use the QuARS tool to extract variability information from requirements documents. The main functionality of QuARS is to detect ambiguity in Natural Language (NL) requirement documents. Ambiguity in requirements may be due to intentional or unintentional indication of possible variability; an ambiguity detecting tool can hence be useful to analysts and clients to figure the potential of a requirements document to describe a family of different products.Source: SPLC 2019 - 23rd International Systems and Software Product Line Conference, Paris, France, 09-13 September, 2019

QuARS a tool for analysing requirements
Lami G.
Numerous tools and techniques are available for managing requirements. Many are designed to define requirements, provide configuration management, and control distribution. However, there are few automatic tools to support the quality analysis of natural language (NL) requirements. Ambiguity analysis and consistency and completeness verification are usually carried out by human reviewers who read requirements documents and look for defects. This clerical activity is boring, time consuming, and often ineffective. This report describes a disciplined method and a related automated tool that can be used for the analysis of NL requirements documents. The tool, called the Quality Analyzer for Requirements Specifications (QuARS), makes it easier to extract structured information and metrics for detecting linguistic inaccuracies and defects. QuARS allows requirements engineers to perform an initial parsing of requirements by automatically detecting potential linguistic defects that can cause ambiguity problems at later stages of software product development. The tool also provides support for the consistency and completeness analysis of the requirements.Source: ISTI Technical reports, 2005

QuARS Express: A Tool for Evaluating Natural Language Requirements
Bucchiarone A., Gnesi S., Lami G., Trentanni G., Fantechi A.
Requirements analysis is an important phase in a software project. It is often performed in an informal way by specialists who review documents looking for ambiguities, technical inconsistencies and incompleteness. Automatic evaluation of Natural Language (NL) requirements documents has been proposed as a means to improve the quality of the system under development. We show how the tool QUARS EXPRESS, introduced in a quality analysis process, is able to manage complex and structured requirement documents containing metadata, and to produce an analysis report rich of categorized information that points out linguistic defects and indications about the writing style of NL requirements. In this paper we report our experience in the automatic analysis of a large collection of natural language requirements, produced inside the MODCONTROL project using this tool.Source: ISTI Technical reports, 2011
