Extracting Movement-based Topics for Analysis of Space Use
(The Eurographics Association, 2023)We present a novel approach to analyze spatio-temporal movement patterns using topic modeling. Our approach represents trajectories as sequences of place visits and moves, applies topic modeling separately to each collection ... -
Feature Alignment for the Analysis of Verbatim Text Transcripts
(The Eurographics Association, 2017)In the research of deliberative democracy, political scientists are interested in analyzing the communication models of discussions, debates, and mediation processes with the goal of extracting reoccurring discourse patterns ... -
Feature-Based Visual Analytics for Studying Simulations of Dynamic Bi-Stable Spatial Systems
(The Eurographics Association, 2013)Simulations of dynamic bi-stable spatial systems usually generate large and complex data that are hard to evaluate. In this paper, we describe how visual analytics technology can help in analyzing such simulation data. The ... -
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 ... -
A Framework for the Multi-Temporal Analysis of Land Cover Change using Visual Analytics
(The Eurographics Association, 2011)Land cover change analysis serves as a basis for planning processes in a wide range of applications. For this task, the use of remote sensing data has become more popular over the last decades. However, despite much research ... -
From Ill-defined Problems to Informed Decisions
(The Eurographics Association, 2014)Decision makers such as military leaders and security analysts are increasingly being asked to make decisions on ill-defined problems. These problems may contain uncertain or incomplete data, and are often complex to piece ... -

(Eurographics Association, 2015) -
A Generic Model for Projection Alignment Applied to Neural Network Visualization
(The Eurographics Association, 2020)Dimensionality reduction techniques are popular tools for the visualization of neural network models due to their ability to display hidden layer activations and aiding the understanding of how abstract representations are ... -
Gnaeus: Utilizing Clinical Guidelines for Knowledge-assisted Visualisation of EHR Cohorts
(The Eurographics Association, 2015)The advanced visualization of electronic health records (EHRs), supporting a scalable analysis from single patients to cohorts, intertwining patients' conditions with executed treatments, and handling the complexity of ... -
Graph Visualization Using Hierarchical Edge Routing and Bundling
(The Eurographics Association, 2012)Driven by rapidly growing application areas such as semantic knowledge bases and social networks, visualization of large graphs has been gaining importance recently. A large amount of nodes and intersecting edges presents ... -
Guidance for Multi-Type Entity Graphs from Text Collections
(The Eurographics Association, 2017)The visual exploration of graphs encoding relationships between entities of multiple types (e.g., persons, locations,...) supports journalists in finding newsworthy information in large text collections. Journalists may ... -
Guidance or No Guidance? A Decision Tree Can Help
(The Eurographics Association, 2018)Guidance methods have the potential of bringing considerable benefits to Visual Analytics (VA), alleviating the burden on the user and allowing a positive analysis outcome. However, the boundary between conventional VA ... -
Guided Sketching for Visual Search and Exploration in Large Scatter Plot Spaces
(The Eurographics Association, 2014)Recently, there has been an interest in methods for filtering large scatter plot spaces for interesting patterns. However, user interaction remains crucial in starting an explorative analysis in a large scatter plot space. ... -
How Sensemaking Tools Influence Display Space Usage
(The Eurographics Association, 2017)We explore how the availability of a sensemaking tool influences users' knowledge externalization strategies. On a large display, users were asked to solve an intelligence analysis task with or without a bidirectionally ... -
Human-Based and Automatic Feature Ideation for Time Series Data: A Comparative Study
(The Eurographics Association, 2023)Feature ideation is a crucial early step in the feature extraction process, where new features are extracted from raw data. For phenomena existing in time series data, this often includes the ideation of statistical ... -
Immersive 3D Visualization of Multi-Modal Brain Connectivity
(The Eurographics Association, 2021)In neuroscience, the investigation of connectivity between different brain regions suffers from the lack of adequate solutions for visualizing detected networks. One reason is the high number of dimensions that have to be ... -
Immersive Analytics of Heterogeneous Biological Data Informed through Need-finding Interviews
(The Eurographics Association, 2021)The goal of this work is to improve existing biological analysis processes by means of immersive analytics. In a first step, we conducted need-finding interviews with 12 expert biologists to understand the limits of current ... -
Inspector Gadget: Integrating Data Preprocessing and Orchestration in the Visual Analysis Loop
