支持流体探索性搜索的交互式视觉方面

Interactive Visual Facets to Support Fluid Exploratory Search

摘要:

探索性搜索从定义不明确的目标开始,包括浏览、学习和制定新的搜索目标。为了流畅地支持这种动态搜索行为,我们专注于设计交互式视觉方面(IVF),可视化信息方面,以支持用户的理解和控制的信息空间。为此,我们回顾了现有的分面搜索界面,并得出了两个尚未完全解决的设计要求(DR),以支持探索性搜索中的流体相互作用。然后,我们通过设计一个IVF工具来举例说明这些要求,该工具分别协调代表项目分布和汇总的线性和分类方面,并为多方面探索(DR 1)提供背景。为了支持搜索条件(DR 2)之间的快速转换,该工具引入了一种新颖的设计概念,即使用方面来选择项目,而无需过滤项目空间。特别是,我们提出了一种过滤器滑动技术,使用户能够拖动一个分类方面的线性方面的酒吧顺序查看项目的交叉点的两个方面,以及分类方面动态总结的项目在互动。三个应用程序演示了这些功能如何轻松地支持信息发现。一项针对11名参与者的用户研究表明,通过时间轴导航的动态建议可以帮助发现有用的搜索建议;新的设计概念比使用方面值作为过滤器更受欢迎。基于这些实践,我们推导出IVF设计对流体、探索性搜索的影响。

英文摘要:

Exploratory search starts with ill-defined goals and involves browsing, learning, and formulating new targets for search. To fluidly support such dynamic search behaviours, we focus on devising interactive visual facets (IVF), visualising information facets to support user comprehension and control of the information space. To do this, we reviewed existing faceted search interfaces and derived two design requirements (DR) that have not been fully addressed to support fluid interactions in exploratory search. We then exemplified the requirements through devising an IVF tool, which coordinates a linear and a categorical facet representing the distribution and summarisation of items, respectively, and providing context for faceted exploration (DR1). To support rapid transitions between search criteria (DR2), the tool introduces a novel design concept of using facets to select items without filtering the item space. Particularly, we propose a filter-swipe technique that enables users to drag a categorical facet value sequentially over linear facet bars to view the items in the intersection of the two facets along with the categorical facet dynamically summarizing the items in the interaction. Three applications demonstrate how the features support information discovery with ease. A user study of 11 participants with realistic email search tasks shows that dynamic suggestions through the timeline navigation can help discover useful suggestions for search; the novel design concept was favoured over using facet values as filters. Based on these practices, we derive IVF design implications for fluid, exploratory searches.
