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 ...
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. ...
Visualization of Spatial and Temporal Pollution Exposure through a Temporal Ordered Spacial Matrix
(The Eurographics Association, 2019)
Poor air quality impacts public health due to increased incidences of serious health conditions; yet the data obtained about pollution is recorded at coarse resolution. Such resolution fails to capture known microclimates ...
Exploring Uncertainty in Image Segmentation Ensembles
(The Eurographics Association, 2018)
Finding the most accurate image segmentation involves analyzing results from different algorithms or parameterizations. In this work, we identify different types of uncertainty in this analysis that are represented by the ...
Model-Agnostic Visual Explanation of Machine Learning Models Based on Heat Map
(The Eurographics Association, 2019)
It is essential to assess the trustworthiness of the machine learning models when deploying them to real-world applications, such as healthcare and risk management, in which domain experts need to make critical decisions. ...
A Study on Reflecting User's Emotions Using a Painterly Rendering System

Shapes of Time: Visualizing Set Changes Over Time in Cultural Heritage Collections
(The Eurographics Association, 2019)
In cultural heritage collections, categorization is a central technique used to distinguish cultural movements, styles, or genres. For that end, objects are tagged with set-typed metadata and other information, such as ...
A Multi-Scale Animation Framework for Biological Fibrous Structures
(The Eurographics Association, 2019)
Fibrous structures are ubiquitous in cell biology and play essential structural and functional roles in the life cycle of a cell. They are long polymers, such as DNA carrying genetic information, or filaments forming the ...
