Description
Summary:Early stages of system development involve outlining desired features such as functionality, availability, or usability. Specifications are derived from these features that concretize vague ideas presented in natural languages. The challenge for the verification and validation of specifications arises from the syntax and semantic gap between different representations and the need of automatic tools. In this paper, we present a requirement-consistency maintenance framework to produce consistent representations. The first part is the automatic translation from natural languages describing functionalities to formal logic with an abstraction of time. It extends pure syntactic parsing by adding semantic reasoning and the support of partitioning input and output variables. The second part is the use of synthesis techniques to examine if the requirements are consistent in terms of realizability. When the process fails, the formulas that cause the inconsistency are reported to locate the problem.
