AMPLIO VQA - A Web Based Visual Query Analysis System for Micro Grid Energy Mix Planning
(The Eurographics Association, 2012)Micro grid technology brings the opportunity to integrate renewable energies with a traditional energy mix on a regional level and to achieve specific local goals. To obtain an optimal energy mix plan, different scenarios ... -
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 ... -
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, ... -
MultiNode-Explorer: A Visual Analytics Framework for Generating Web-based Multimodal Graph Visualizations
(The Eurographics Association, 2012)We propose MultiNode-Explorer, a visual analytics framework that is capable of transforming multidimensional datasets into an entity-relationship (E-R) model and visualizing the data as node-link diagrams. The framework ... -
The News Auditor: Visual Exploration of Clusters of Stories
(The Eurographics Association, 2012)In recent years, the quantity of content generated by news agencies and blogs is constantly growing, making it difficult for readers to process and understand this overwhelming amount of data. Online news aggregators present ... -
Ontology Visualization: One Size Does Not Fit All
(The Eurographics Association, 2012)Visualization techniques have been used for ontology representation to allow the comprehension of concepts and properties in specific domains. Due to the complexity and size of ontologies such techniques need to be efficient ... -
PCDC - On the Highway to Data - A Tool for the Fast Generation of Large Synthetic Data Sets
(The Eurographics Association, 2012)In this paper, we present Parallel Coordinates for Data Creation (PCDC), a new visual-interactive method for the fast generation of labeled multidimensional data sets. Multivariate data need to be analyzed in various domains ... -
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 ... -
Supporting Visual Analysis in Smart Meeting Rooms
(The Eurographics Association, 2012)Smart meeting rooms as a specific form of multi-display environments (MDE) feature ad-hoc ensembles of heterogeneous devices and software tools to facilitate collective work and information sharing between multiple users. ... -
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 ... -
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 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 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 ... -
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 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 ... -
Visual Text Analytics using Semantic Networks and Interactive 3D Visualization
(The Eurographics Association, 2012)Facing the growth of textual information, the analysis of unstructured text data remains a challenge for visual analytics. Most text visualizations are based on models that use word frequencies for text vectorization and ...
