Abstract

The representation of traceability links in requirements knowledge is vital to improve the general understanding of requirements as well as the relevance and consequences of relations between requirements artifacts and other artifacts in software engineering. Various visualization techniques have been developed to support the representation of traceability information, e.g. traceability matrices, graphs and tree structures. However, these techniques do not scale well on large amounts of artifacts and often do not provide additional functionality to present supplementary data. In this paper, we use Sunburst and Netmap visualizations as alternative visualization techniques. These techniques perform well even on large amounts of artifacts and traceability links. Moreover, they provide the ability to present derivative data. An implementation of the visualizations was developed in conjunction with a requirements plugin for the Redmine project management platform. In this paper, the applicability of Sunburst and Netmap visualizations for requirements engineering knowledge is illustrated by applying it to an example project and the results are compared to traditional visualization techniques.

使用Sunburst和Netmap可视化改进了需求工程知识中可追溯性链接的表示
需求知识中可追溯性链接的表示对于提高对需求的一般理解以及软件工程中需求工件与其他工件之间关系的相关性和结果是至关重要的。各种可视化技术已经被开发出来,以支持可追溯性信息的表示,例如可追溯性矩阵、图和树结构。然而,这些技术不能很好地扩展到大量工件上,并且通常不能提供额外的功能来表示补充数据。在本文中,我们使用Sunburst和Netmap可视化作为替代的可视化技术。这些技术即使在大量的工件和可追溯性链接上也能很好地执行。此外,它们还提供了呈现衍生数据的能力。可视化的实现是与Redmine项目管理平台的需求插件一起开发的。本文通过实例工程说明了Sunburst和Netmap可视化技术在需求工程知识方面的适用性,并将结果与传统可视化技术进行了比较。
