Elastic Tree Layouts for Interactive Exploration of Mentorship
(The Eurographics Association, 2021)
Mentorship is an important collaborative relationship among scholars. The existing tools to visualize it mainly suffer from a waste of space, lack of overview representation, and less displayed attribute information. To ...
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 ...
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 ...
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 ...
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 Reactionary Train Delay from an Agent Based Model
(The Eurographics Association, 2019)
We design and apply interactive visualisation to help understand reactionary (knock-on) delay in trains using a set of 'Monte- Carlo' style Agent Based Model runs, and to help train operating companies design interventions. ...
Supporting Visual Parameter Analysis of Time Series Segmentation with Correlation Calculations
(The Eurographics Association, 2018)
Parameter analysis can be used to find out how individual parameters influence the output of an algorithm. We aim to support the visual parameter analysis of algorithms for the segmentation of time series. To this end, we ...
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 ...
Towards Natural Language Empowered Interactive Data Analysis
(The Eurographics Association, 2018)
The recent advances in natural language based interaction methodologies offer promising avenues to enhance the interactive processes within the human-machine dialogue of visual analytics. We envisage Multimodal Data Analytics ...
