Interactive Hierarchical Quote Extraction for Content Insights
(The Eurographics Association, 2019)
This work presents a new approach to visually summarize large micro-document collections such as tweets. We extract frequent patterns of phrases as shortened quotes to present analysts an overview of popular snippets and ...
Learning a Perceptual Quality Metric for Correlation in Scatterplots
(The Eurographics Association, 2019)
Visual quality metrics describe the quality and efficiency of multidimensional data visualizations in order to guide data analysts during exploration tasks. Current metrics are usually based on empirical algorithms which ...
On Quality Indicators for Progressive Visual Analytics
(The Eurographics Association, 2019)
A key component in using Progressive Visual Analytics (PVA) is to be able to gauge the quality of intermediate analysis outcomes. This is necessary in order to decide whether a current partial outcome is already good enough ...
Visual Analytics of Event Data using Multiple Mining Methods
(The Eurographics Association, 2019)
Most researchers use a single method of mining to analyze event data. This paper uses case studies from two very different domains (electronic health records and cybersecurity) to investigate how researchers can gain ...
The Human User in Progressive Visual Analytics
(The Eurographics Association, 2019)
The amount of generated and analyzed data is ever increasing, and processing such large data sets can take too long in situations where time-to-decision or fluid data exploration are critical. Progressive visual analytics ...
CoCoa: A Linked Network Visualization System of Co-citation and Co-author Relationships
(The Eurographics Association, 2019)
We usually use a text-based search engine while surveying research papers. Such search systems have difficulties for novice researchers in case they do not know appropriate keywords or do not understand the positions of ...
A Review of Guidance Approaches in Visual Data Analysis: A Multifocal Perspective
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Visual data analysis can be envisioned as a collaboration of the user and the computational system with the aim of completing a given task. Pursuing an effective system-user integration, in which the system actively helps ...
Visual Analysis of Multivariate Urban Traffic Data Resorting to Local Principal Curves
(The Eurographics Association, 2019)
Traffic congestion causes major economic, environmental and social problems in modern cities. We present an interactive visualization tool to assist domain experts on the identification and analysis of traffic patterns at ...
Visual-Interactive Exploration of Pathogen Outbreaks in Hospitals
(The Eurographics Association, 2019)
Clinicians and hygienists need to identify outbreaks and transmission patterns of pathogen infections among hospital patients. Such analysis requires the combination of the microbiological laboratory results with the ...
