    • 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 ...

    • PCDC - On the Highway to Data - A Tool for the Fast Generation of Large Synthetic Data Sets 

      Bremm, Sebastian; Heß, Martin; Landesberger, Tatiana von; Fellner, Dieter W. (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 ...

    • Supporting Visual Analysis in Smart Meeting Rooms 

      Radloff, Axel; Fuchs, Georg; Schumann, Heidrun (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. ...
