复杂、功能丰富的软件包的教程和示例工作流在网上广泛可用。因此，用户必须区分工作流，以选择最适合其任务的工作流。我们提出三角洲，一个交互式的工作流可视化和比较工具，帮助用户确定工作流之间的权衡。我们进行了一项初步研究，以确定用户在比较工作流时所关注的属性集，发现他们考虑结果质量，他们对命令的了解以及工作流的效率。然后，我们设计了Delta来在三个粒度上显示这些属性：一个高级别的集群视图;一个包含工作流摘要的中间级别列表视图;以及一个允许用户比较两个单独工作流的低级别细节视图。最后，我们进行了一个小语料库的30个工作流的Delta的评估，发现中间列表视图提供了最好的信息密度。最后，我们的想法，这样的工作流程比较系统可以在未来扩大到更大的语料库。
Tutorials and sample workflows for complicated, feature-rich software packages are widely available online. As a result users must differentiate between workflows to choose the most suitable one for their task. We present Delta, an interactive workflow visualization and comparison tool that helps users identify the tradeoffs between workflows. We conducted an initial study to identify the set of attributes users attend to when comparing workflows, finding that they consider result quality, their knowledge of commands, and the efficiency of the workflow. We then designed Delta to surface these attributes at three granularities: a high-level, clustered view; an intermediate-level list view that contains workflow summaries; and a low-level detail view that allows users to compare two individual workflows. Finally, we conducted an evaluation of Delta on a small corpus of 30 workflows and found that the intermediate list view provided the best information density. We conclude with thoughts on how such a workflow comparison system could be scaled up to larger corpora in the future.
