面向目标的建模是需求工程领域最重要的研究进展之一。本文系统地分析了面向目标的语言之一i* 的可视化语法。像大多数RE符号一样，i* 是高度可视化的。然而令人惊讶的是，自从十多年前提出以来，几乎没有关于其图形约定的争论或修改。我们使用一组设计认知有效的视觉符号（符号物理学）的原则来评估i* 视觉符号。分析揭示了符号中的一些严重缺陷，并提出了一些实际的改进建议。研究结果可用于提高其在实践中的有效性，特别是与最终用户的沟通。一个更广泛的目标，该文件是提高认识的重要性，视觉表示在RE研究，这在历史上很少受到关注。
Goal-oriented modelling is one of the most important research developments in the requirements engineering (RE) field. This paper conducts a systematic analysis of the visual syntax of i*, one of the leading goal-oriented languages. Like most RE notations, i* is highly visual. Yet surprisingly, there has been little debate about or modification to its graphical conventions since it was proposed more than a decade ago. We evaluate the i* visual notation using a set of principles for designing cognitively effective visual notations (the Physics of Notations). The analysis reveals some serious flaws in the notation together with some practical recommendations for improvement. The results can be used to improve its effectiveness in practice, particularly for communicating with end users. A broader goal of the paper is to raise awareness about the importance of visual representation in RE research, which has historically received little attention.
