STEIN: Speeding up Evaluation Activities With a Seamless Testing Environment INtegrator
(The Eurographics Association, 2018)
The evaluation of an information visualization system is a complex activity, involving the understanding of both the visualization itself and the process that it is meant to support. Moreover, if the evaluation activity ...
Visual Analysis of Sentiment and Stance in Social Media Texts
(The Eurographics Association, 2018)
Despite the growing interest for visualization of sentiments and emotions in textual data, the task of detecting and visualizing various stances is not addressed well by the existing approaches. The challenges associated ...
Visual Analysis of Geo-spatial Data in 3D Terrain Environments using Focus+Context
(The Eurographics Association, 2017)
Visual analysis of geo-spatial data represented within a three-dimensional frame of reference is a challenging task. Focus+ Context is a common concept that aids this process. This paper addresses the question, how ...
Visually Exploring Data Provenance and Quality of Open Data
(The Eurographics Association, 2018)
While open data platforms are increasingly popular among end-users as well as data providers, there is a growing problem with inconsistent update frequencies and lack of quality in datasets. Efforts to monitor data quality ...
ConTraffic Visual Analytics in Support to Customs Risk-Analysis
(The Eurographics Association, 2017)
Customs risk analysis is crucial for detecting fraud and contraband goods in the massive flows of internationally traded goods. Most of non-bulk goods are transported in shipping containers and, as customs can control only ...
Panning for Insight: Amplifying Insight through Tight Integration of Machine Learning, Data Mining, and Visualization
(The Eurographics Association, 2018)
With the rapid progress made in Data Mining, Visualization, and Machine Learning during the last years, combinations of these methods have gained increasing interest. This paper summarizes ideas behind ongoing work on ...
Comparative Visual Analysis of Pelvic Organ Segmentations
(The Eurographics Association, 2018)
In prostate cancer treatment, automatic segmentations of the pelvic organs are often used as input to radiotherapy planning systems. However, natural anatomical variability of the involved organs is a common reason, for ...
Visualizing Functional Regions by Analysis of Geo-textual Data
(The Eurographics Association, 2018)
Using tremendous geo-textual data collected from social media applications, we facilitate the analysis of region functions. By extracting semantics from textual properties, we aim at classifying geographical locations in ...
Visually Analyzing Parameter Influence on Optical Coherence Tomography Data in Ophthalmology
(The Eurographics Association, 2017)
Optical coherence tomography (OCT) enables noninvasive high-resolution imaging of the human retina and therefore, plays a fundamental role in detecting a wide range of ocular diseases. Yet, OCT data often vary in quality ...
Visual Analysis of Urban Traffic Data based on High-Resolution and High-Dimensional Environmental Sensor Data
(The Eurographics Association, 2018)
Urbanization is an increasing global trend resulting in a strong increase in public and individual transportation needs. Accordingly, a major challenge for traffic and urban planners is the design of sustainable mobility ...
