如何创造有效、美观的可视化表征以达到“一眼洞穿真相”的效果,一直是可视化领域的研究目标。经过学者们多年的努力,我们已经有了很多新颖的可视化表达方法,包括常用的折线图、散点图、平行坐标等。但对于普通用户来说,许多炫目的可视化技术往往“只可远观而不能亵玩”,因为用户难以权衡哪种方法最能有效的呈现数据特征。即使户选择了某种可视化方法,该方法所对应的复杂可视化视觉编码参数仍然可能使其陷入“选择困境”。 为解决该困境,我们提出了任务驱动的自动可视化技术,本次报告将分享我们最近的一些相关工作。

报告题目:SkyLens: Visual Analysis of Skyline on Multi-dimensional Data


Skyline queries have wide-ranging applications in fields that involve multi-criteria decision making, including tourism, retail industry, and human resources. By automatically removing incompetent candidates, skyline queries allow users to focus on a subset of superior data items (i.e., the skyline), thus reducing the decision-making overhead. However, users are still required to interpret and compare these superior items manually before making a successful choice. This task is challenging because of two issues. First, people usually have fuzzy, unstable, and inconsistent preferences when presented with multiple candidates. Second, skyline queries do not reveal the reasons for the superiority of certain skyline points in a multi-dimensional space. To address these issues, we propose SkyLens, a visual analytic system aiming at revealing the superiority of skyline points from different perspectives and at different scales to aid users in their decision making. Two scenarios demonstrate the usefulness of SkyLens on two datasets with a dozen of attributes. A qualitative study is also conducted to show that users can efficiently accomplish skyline understanding and comparison tasks with SkyLens.
