      The automatic detection and classification of stance taking in text data using natural language processing and machine learning methods create an opportunity to gain insight about the writers' feelings and attitudes towards ...
    • Transfer Function Optimization Based on a Combined Model of Visibility and Saliency 

      Luo, Shengzhou; Dingliana, John (The Eurographics Association, 2016)
      We present an automated technique to optimize the clarity of features in visualizations of 3D volume datasets. By adjusting the opacity transfer function, we achieve user-specified target distributions of feature conspicuity. ...
    • Tracking and Visualizing Dynamic Structures in Multichannel EEG Coherence Networks 

      Ji, Chengtao; Gronde, J. J. van de; Maurits, N. M.; Roerdink, Jos B. T. M. (The Eurographics Association, 2016)
      An electroencephalography (EEG) coherence network represents functional brain connectivity, and is constructed by calculating the coherence between pairs of electrode signals as a function of frequency. Visualization of ...
    • Coloring Interactive Compositional Dot Maps 

      Tennekes, Martijn; Jonge, Edwin de (The Eurographics Association, 2016)
      We propose an algorithmic color scheme for zoom-able compositional dot maps. Contrary to existing methods, it uses density, composition, and zoom level to color the pixels of the resulting dot map. We describe the method ...
    • Visual Data Exploration for Balance Quantification During Exergaming 

      Soancatl, Venustiano; Gronde, J. J. van de; Lamoth, C. J. C.; Maurits, N. M.; Roerdink, Jos B. T. M. (The Eurographics Association, 2016)
      Recently, digital games controlled by real-time body movements (exergames) have been proposed as an innovative method to improve balance among older adults. One of the main challenges for exergames is to automatically ...
    • MetricScalpel: Analyzing Diagnostic Outcomes with Exploratory Data Visualization 

      Li, Wei; Elderman, Joep; Hoogerwoord, Erwin; Funk, Mathias; Brombacher, Aarnout C. (The Eurographics Association, 2016)
      Healthcare data is the emerging force to push ahead smarter clinical solutions. However, unforeseen challenges like unmanaged massive data and costly access to it make it difficult for domain experts to easily derive ...
    • When Individual Data Points Matter: Interactively Analysing Classification Landscapes 

      Schneider, Bruno; Mittelstädt, Sebastian; Keim, Daniel A. (The Eurographics Association, 2016)
      The selection of classification models among several options with similar accuracy cannot be done through purely automated methods, and especially in scenarios in which the cost of misclassified instances is crucial, such ...
    • Quantitative Evaluation for Edge Bundling Based on Structural Aesthetics 

      Saga, Ryosuke (The Eurographics Association, 2016)
      This study proposes a method to evaluate the efficiency of edge bundling. Edge bundling is important to improve visual clutter of edge visualization. However, the evaluation of edge bundling is based only on qualitative ...
    • Hierarchical Clustering with Multiple-Height Branch-Cut Applied to Short Time-Series Gene Expression Data 

      Vogogias, Athanasios; Kennedy, Jessie; Archambault, Daniel (The Eurographics Association, 2016)
      Rigid adherence to pre-specified thresholds and static graphical representations can lead to incorrect decisions on merging of clusters. As an alternative to existing automated or semi-automated methods, we developed a ...
