Visual Analytics of Microblog Data for Pandemic and Crisis Analysis
(The Eurographics Association, 2012)
Microblogging is a rich and plentiful source of data that contains potentially valuable information amidst noise. This work presents software that extracts useful metadata from a microblog dataset to explore and analyze ...
Visual Analysis of Public Transport Vehicle Movement
(The Eurographics Association, 2012)
Public transport vehicles record detailed operational logs. In major networks, this quickly amounts to massive datasets. Traditionally, these are analysed only using statistical tools, yet they show great potential for the ...
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 ...
Visual Analytics for Dynamic Evacuation Planning
(The Eurographics Association, 2012)
We use visual analytics to assist human experts in the verification of evacuation schedules and enable them to identify the bottle-necks in building evacuation. The user can change parameters, such as the number of occupants ...
A System for Query Based Analysis and Visualization
(The Eurographics Association, 2012)
Today scientists are producing large volumes of data that they wish to explore and visualize. In this paper we describe a system that combines range-based queries with fast lookup to allow a scientist to quickly and ...
Scalable Cluster Analysis of Spatial Events
(The Eurographics Association, 2012)
Clustering of massive data is an important analysis tool but also challenging since the data often does not fit in RAM. Many clustering algorithms are thus severely memory-bound. This paper proposes a deterministic density ...
Developing an Extended Task Framework for Exploratory Data Analysis Along the Structure of Time
(The Eurographics Association, 2012)
Exploratory data analysis of time-oriented data is an important goal that Visual Analytics has to tackle. When users from real-world domains are asked about time-oriented tasks, they often refer to the unique structure of ...
Visual Exploration of Feature-Class Matrices for Classification Problems
(The Eurographics Association, 2012)
When a classification algorithm does not work on a data set, it is a non-trivial problem to figure out what went wrong on a technical level. It is even more challenging to communicate findings to domain experts who can ...
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 ...
Interactive Visual Analysis of Ethological Studies: Getting Insight from Large Ensembles of Animals' Paths
(The Eurographics Association, 2012)
In this paper we describe how interactive visual analysis can be efficiently used to analyze a large ensemble of animal paths. Behavioral studies of animals are carried out in order to gain new insight in animal behavior, ...
