Dynamic Visual Abstraction of Soccer Movement
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Trajectory-based visualization of coordinated movement data within a bounded area, such as player and ball movement within a soccer pitch, can easily result in visual crossings, overplotting, and clutter. Trajectory ...
NEREx: Named-Entity Relationship Exploration in Multi-Party Conversations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Abstract We present NEREx, an interactive visual analytics approach for the exploratory analysis of verbatim conversational transcripts. By revealing different perspectives on multi-party conversations, NEREx gives an entry ...
Interactive Ambiguity Resolution of Named Entities in Fictional Literature
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Named entity recognition (NER) denotes the task to detect entities and their corresponding classes, such as person or location, in unstructured text data. For most applications, state of the art NER software is producing ...
SurgeryCuts: Embedding Additional Information in Maps without Occluding Features
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
Visualizing contextual information to a map often comes at the expense of overplotting issues. Especially for use cases with relevant map features in the immediate vicinity of an information to add, occlusion of the relevant ...
Comparative Analysis with Heightmaps in Virtual Reality Environments
(The Eurographics Association, 2019)
3D heightmaps can be considered as an extension of heatmaps using the third dimension to encode the respective value by height, often in addition to encoding it by color. In contrast to 2D heatmaps, 3D heightmaps allow a ...
ColorCAT: Guided Design of Colormaps for Combined Analysis Tasks
(The Eurographics Association, 2015)
Colormap design is challenging because the encoding must match the requirements of data and analysis tasks as well as the perception of the target user. A number of well-known tools exist to support the design of colormaps. ...
Ambient Grids: Maintain Context-Awareness via Aggregated Off-Screen Visualization
(The Eurographics Association, 2015)
When exploring large spatial datasets, zooming and panning interactions often lead to the loss of contextual overview. Existing overview-plus-detail approaches allow users to view context while inspecting details, but they ...
Visual Analysis of Explicit Opinion and News Bias in German Soccer Articles
(The Eurographics Association, 2012)
Most state-of-the-art opinion and sentiment analysis techniques were developed for customer feedback data or reviews. Applying them to another domain is often not possible because the algorithms are based on the assumption ...
Integrated Spatial Uncertainty Visualization using Off-screen Aggregation
(The Eurographics Association, 2015)
Visualization of spatial data uncertainties is crucial to the data understanding and exploration process. Scientific measurements, numerical simulations, and user generated content are error prone sources that gravely ...
DYNEVI - DYnamic News Entity Visualization
(The Eurographics Association, 2010)
Dynamic news entity visualization shows an implementation of visualizing news entity data to give an overview as well as to display emerging and vanishing news topics. We present a robust and dynamic visualization system ...
