Semantic Filtering of Textual Requirements Descriptions

This paper explores the use of semantic filtering techniques for the analysis of large textual requirements descriptions. Our approach makes use of the Contextual Exploration Method to extract, within large textual requirements descriptions, those statements considered as relevant from requirements engineering perspective: concepts relationships, aspecto-temporal organisation, cause and control statements. We investigate to what extent filtering with these criteria can be the base of requirements analysis and validation processing, and what kind of software tools are necessary to support contextual exploration systems for this purpose.
