  • Visual Analysis of Public Transport Vehicle Movement 

    Wörner, Michael; Ertl, Thomas (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 ...

  • Graph Visualization Using Hierarchical Edge Routing and Bundling 

    Kienreich, Wolfgang; Wozelka, Ralph; Sabol, Vedran; Seifert, Christin (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 

    Matkovic, Kresimir; Winding, Christiana; Splechtna, Rainer; Balka, Michael (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, ...

  • Ontology Visualization: One Size Does Not Fit All 

    Silva, Isabel da; Santucci, Giuseppe; Freitas, Carla del Sasso (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 ...

  • Visual Analytics of Microblog Data for Pandemic and Crisis Analysis 

    Pritchard, Iwan C.; Walker, Rick; Roberts, Jonathan C. (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 ...

  • MultiNode-Explorer: A Visual Analytics Framework for Generating Web-based Multimodal Graph Visualizations 

    Ghani, Sohaib; Elmqvist, Niklas; Ebert, David S. (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 

    Behrisch, Michael; Krstajic, Milos; Schreck, Tobias; Keim, Daniel A. (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 ...

  • AMPLIO VQA - A Web Based Visual Query Analysis System for Micro Grid Energy Mix Planning 

    Stoffel, Andreas; Zhang, Leishi; Weber, Stefan Hagen; Keim, Daniel A. (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 ...

  • Visual Analysis of Explicit Opinion and News Bias in German Soccer Articles 

    Oelke, Daniela; Geißelmann, Benno; Keim, Daniel A. (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 ...

  • Developing an Extended Task Framework for Exploratory Data Analysis Along the Structure of Time 

    Lammarsch, Tim; Rind, Alexander; Aigner, Wolfgang; Miksch, Silvia (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 

    Kienreich, Wolfgang; Seifert, Christin (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 

    Drieger, Philipp (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 ...

  • A System for Query Based Analysis and Visualization 

    Sanderson, Allen R.; Whitlock, Brad; Rübel, Oliver; Childs, Hank; Weber, Gunther; Prabhat, Mr; Wu, Kenseng (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 

    Peca, Iulian; Fuchs, Georg; Vrotsou, Katerina; Andrienko, Natalia; Andrienko, Gennady (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 ...

  • Visual Analytics for Dynamic Evacuation Planning 

    Reddy, Rajesh; Höferlin, Markus; Dambier, Michael; Weiskopf, Daniel (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 ...
