Visual Exploration of Spatial and Temporal Variations of Tweet Topic Popularity
(The Eurographics Association, 2018)
We present a visual analytical approach to exploring variation of topic popularity in social media (such as Twitter) over space and time. Our approach includes an analytical pipeline and a multi-view visualization tool. ...
Enhanced Attribute-Based Explanations of Multidimensional Projections
(The Eurographics Association, 2020)
Multidimensional projections (MPs) are established tools for exploring the structure of high-dimensional datasets to reveal groups of similar observations. For optimal usage, MPs can be augmented with mechanisms that explain ...
Towards Privacy-Preserving Semantic Mobility Analysis
(The Eurographics Association, 2013)
By analyzing data reflecting human mobility, one can derive patterns and knowledge that are tightly linked to the underlying geography and therefore cannot be applied to another territory or even compared with patterns ...
Visual Analytics to Check Marine Containers in the Eritr\@c Project
(The Eurographics Association, 2010)
The Eritr@c project is a European project aiming at developing an inspection system to control marine containers for illicit or dangerous materials. The system is made of a neutron generator, a set of sensors, and an ...
Frontmatter: EuroVA 2015 EuroVis Workshop on Visual Analytics
(Eurographics Association, 2015)
A Concept for Consensus-based Ordering of Views
(The Eurographics Association, 2018)
High-dimensional data poses a significant challenge for analysis, as patterns typically exist only in subsets of dimensions or records. A common approach to reveal patterns, such as meaningful structures or relationships, ...
A Visual Analytics Field Experiment to Evaluate Alternative Visualizations for Cyber Security Applications
(The Eurographics Association, 2014)
The analysis and exploration of emerging threats in the Internet is important to better understand the behaviour of attackers and develop new methods to enhance cyber security. Fully automated algorithms alone are often ...
Visual Analytics of Conversational Dynamics
(The Eurographics Association, 2019)
Large-scale interaction networks of human communication are often modeled as complex graph structures, obscuring temporal patterns within individual conversations. To facilitate the understanding of such conversational ...
Finding Arbitrary Shaped Clusters with Related Extents in Space and Time
(The Eurographics Association, 2010)
The paper deals with density-based clustering of events, i.e. objects positioned in space and time, such as occurrences of earthquakes, forest fires, mobile phone calls, or photos with geographical references. Finding ...
Visual Grouping - Follow the Leader!
(The Eurographics Association, 2013)
We present an interactive system that provides users with automated techniques for grouping data, while shielding them from the technical aspects of these techniques. In our system users create visual data representations, ...
