在探索性可视化分析过程中建模和利用分析焦点

Modeling and Leveraging Analytic Focus During Exploratory Visual Analysis

Zhilan Zhou, Ximing Wen, Yue Wang, David Gotz

摘要:

可视化分析系统支持高度交互式的探索性数据分析。在一系列领域中,这些技术已经成功地用于帮助用户从复杂的数据中学习。然而,这些相同的探索性可视化技术使用户很容易发现虚假的发现。本文提出了新的方法来监测用户的分析重点在可视化分析的结构化数据集,并使用它来表面相关的文章,上下文的可视化结果。出于电子健康数据的交互式分析,本文介绍了一个正式的分析焦点模型,一种计算方法,动态更新的焦点模型在用户交互的时候,和一个原型应用程序,利用这个模型表面相关的医疗出版物的用户在一个大型语料库的医疗记录的可视化分析。24个用户的评价结果表明,建模方法具有较高的准确性,并能够表面高度相关的医学摘要。

英文摘要:

Visual analytics systems enable highly interactive exploratory data analysis. Across a range of fields, these technologies have been successfully employed to help users learn from complex data. However, these same exploratory visualization techniques make it easy for users to discover spurious findings. This paper proposes new methods to monitor a user's analytic focus during visual analysis of structured datasets and use it to surface relevant articles that contextualize the visualized findings. Motivated by interactive analyses of electronic health data, this paper introduces a formal model of analytic focus, a computational approach to dynamically update the focus model at the time of user interaction, and a prototype application that leverages this model to surface relevant medical publications to users during visual analysis of a large corpus of medical records. Evaluation results with 24 users show that the modeling approach has high levels of accuracy and is able to surface highly relevant medical abstracts.
