NON FUNCTIONAL REQUIREMENT TRACEABILITY AUTOMATION-AN MOBILE MULTIMEDIA APPROACH

Abstract

Requirements Engineering (RE) is the area of softwa re engineering that deals with the discovery and specification of the objectives for the system unde r development and the environment in which it is us ed including the human activities it supports. Require ment Elicitation is process of gathering requiremen ts from stakeholders. Incorporating RE to identify non Functional Requirements (NFR) in early stages of design and implementation avoids ambiguities, confl icting requirement and other defects. The efficacy of the requirement engineering methodology is its abil ity to capture NFR in an efficient manner. In this study, we propose a novel method of elicitation using mobi le multimedia and to automatically trace the NFR. T he requirements description is captured in video using smart phones. Requirement document are prepared using voice to text converter. NFR is detected auto matically from the requirement document and hand gestures emphasise the importance of the requirement. It is observed that the precision and recall of the class ifiers is better using multimedia data. Features were extract ed from video frame and audio using image processing technique and speech processing. We investigated data mining approach to identify Non Functional Requirements (NFR) from Functional Requirement (FR) Documents. Results obtained were satisfactory.
