情景感知的软件需求获取与建模技术综述

情境感知的移动应用能够适应用户当前状态,因此这类应用越来越受到青睐。但由于上下文情景的维度是无数的,这使得获取和建模情境感知系统的情景需求成为一大挑战。本文通过文献综述的方法,旨在:(1)发现有哪些情境感知的需求获取与建模方法;(2)评估这些方法的技术转移成熟度。通过对所选择的61篇相关文献,进行数据抽取和分析综合,本文总结并识别出11种需求获取的方法、10种需求建模的方法以及它们的技术转移现状。结果显示:(1)最受欢迎的情景感知需求获取方法是用例和场景,而最常用的情境感知需求建模方法则是面向目标的方法;(2)在大多数相关文献中的需求获取与建模技术的技术成熟度都不高,不利于其面向工业界进行技术转移。

Context Aware Requirements Elicitation and Modeling Technologies: A Review

Context-aware mobile applications are more and more appealing as they can adapt their behavior to the current situation. But eliciting and modeling the context-aware requirements of these context-aware systems become big challenges as the dimension of contexts are countless. Therefore, learning from the existing studies can help both academia and industry meet the challenges. The main objectives of this study are:(1) finding out the methods used in context-aware requirements elicitation and modeling processes, and(2) evaluating the technology transfer maturity of these methods. The results based on 61 selected studies present 11 requirements elicitation methods, 10 requirements modeling methods, and their technology transfer status are identified. After synthesizing and analyzing, it shows that(1) user case and scenario are the most popular means to elicit context-aware requirements, and various goal-oriented methods are used to model context-aware requirements;(2)the evidences have proven that technology transfer is not well done in majority of these empirical studies.
