    • Mind the Time: Unleashing the Temporal Aspects in Pattern Discovery 

      Lammarsch, T.; Aigner, W.; Bertone, A.; Miksch, S.; Rind, A. (The Eurographics Association, 2013)
      Temporal Data Mining is a core concept of Knowledge Discovery in Databases handling time-oriented data. Stateof- the-art methods are capable of preserving the temporal order of events as well as the information in between. ...

    • Modeling Incremental Visualizations 

      Angelini, Marco; Santucci, Giuseppe (The Eurographics Association, 2013)
      An increasing number of applications call for the incremental/iterative drawing of a visualization. That is an obvious requirement when dealing with continuously changing data, like the emerging field of data streams or ...

    • Towards Privacy-Preserving Semantic Mobility Analysis 

      Andrienko, N.; Andrienko, G.; Fuchs, G. (The Eurographics Association, 2013)
      By analyzing data reflecting human mobility, one can derive patterns and knowledge that are tightly linked to the underlying geography and therefore cannot be applied to another territory or even compared with patterns ...

    • Visual Comparison of Orderings and Rankings 

      Behrisch, Michael; Davey, James; Simon, Svenja; Schreck, Tobias; Keim, Daniel; Kohlhammer, Jörn (The Eurographics Association, 2013)
      In many data analysis problems, sequentially ordered (or ranked) data occurs that needs to be understood and compared. Ranking information is essential in applications such as multimedia search where retrieval rankings ...

    • Visual Grouping - Follow the Leader! 

      Lammers, Thomas; Vliegen, Roel; Linden, Erik-Jan van der; Wetering, Huub van de (The Eurographics Association, 2013)
      We present an interactive system that provides users with automated techniques for grouping data, while shielding them from the technical aspects of these techniques. In our system users create visual data representations, ...

    • Contingency Wheel: Visual Analysis of Large Contingency Tables 

      Alsallakh, Bilal; Groeller, Eduard; Miksch, Silvia; Suntinger, Martin (The Eurographics Association, 2011)
      We present the Contingency Wheel, a visual method for finding and analyzing associations in a large nxm contingency table with m less than 100 and n being two to three orders of magnitude larger than m. The method is ...

    • Steerable Clustering for Visual Analysis of Ecosystems 

      Ahmed, Zafar; Yost, Patrick; McGovern, Amy; Weaver, Chris (The Eurographics Association, 2011)
      One of the great challenges in the geosciences is understanding ecological systems in order to predict changes and responses in space and time at scales from local to global. Ecologists are starting to recognize the value ...

    • A Framework for the Multi-Temporal Analysis of Land Cover Change using Visual Analytics 

      Kinkeldey, C.; Schiewe, J. (The Eurographics Association, 2011)
      Land cover change analysis serves as a basis for planning processes in a wide range of applications. For this task, the use of remote sensing data has become more popular over the last decades. However, despite much research ...

    • Adaptive Interactive Multi-Resolution Computational Steering for Complex Engineering Systems 

      Matkovic, K.; Gracanin, D.; Jelovic, M.; Cao, Y. (The Eurographics Association, 2011)
      Computational steering integrates modeling, computation, data analysis, visualization, and data input components of a simulation. Since the simulation space is, in general, very large and continuous, selecting discrete ...

    • Exploring Complex Mobile Life through Lightweight Visualizations 

      Kim, Tanyoung; Blom, Jan; Stasko, John (The Eurographics Association, 2011)
      Smart phones can be used to collect various types of data from a user spanning call and text message logs to GPS coordinates, and to Bluetooth detection. These data are indicative of behavior across various socio-temporalspatial ...

    • Interactive Analysis of Object Group Changes over Time 

      Bremm, S.; Landesberger, T. von; Andrienko, G.; Andrienko, N.; Schreck, Tobias (The Eurographics Association, 2011)
      The analysis of time-dependent data is an important task in various application domains. Often, the analyzed data objects belong to groups. The group memberships may stem from natural arrangements (e.g., animal herds), or ...

    • Visual Comparison of Ranked Result Cumulated Gains 

      Ferro, N.; Sabetta, A.; Santucci, G.; Tino, G.; Veltri, F. (The Eurographics Association, 2011)
      Ranking is fundamental in Information Retrieval (IR) and several measures have been developed over the years to assess the quality of a ranked result list, such as those based on the idea of computing the cumulative gain ...

    • Visual Analysis of Advanced Manufacturing Simulations 

      Wörner, M.; Ertl, T. (The Eurographics Association, 2011)
      Today's manufacturing companies are faced with requests for highly customer-specific products that come in numerous variants but small numbers of units per variant. Therefore, their manufacturing processes need to be ...

    • Visual Analysis of User Behaviour in Pay-Per-Bid Auctions 

      Walker, Rick; Cenydd, Llyr ap; Pop, Serban; Roberts, Jonathan C. (The Eurographics Association, 2011)
      In pay-per-bid auctions, placing a bid costs a fee, and only raises the price of the item by a small increment. At the conclusion of the auction, the last bidder wins, and the price paid by the winning bidder is subsidised ...

    • Understanding the Role and Value of Interaction: First Steps 

      Aigner, W. (The Eurographics Association, 2011)
      Visual Analytics strongly emphasizes the importance of interaction. However, until now, interaction is only sparingly treated as subject matter on its own. How and why interactivity is beneficial to gain insight and make ...

    • Towards a Concept how the Structure of Time can Support the Visual Analytics Process 

      Lammarsch, T.; Aigner, W.; Bertone, A.; Miksch, S.; Rind, A. (The Eurographics Association, 2011)
      The primary goal of Visual Analytics (VA) is the close intertwinedness of human reasoning and automated methods. An important task for this goal is formulating a description for such a VA process. We propose the design of ...
