Evaluation of Radial and Hierarchical Opinion Visualization Techniques
نویسنده
چکیده
This paper presents a usability study of radial and hierarchical opinion visualization techniques. The objective of this work is to evaluate the selected visualizations based on a set of information visualization metrics. A questionnaire survey was used as an instrument to collect response from users on a 3-point Likert scale. The data were collected by s conducting seminar and an online questionnaire (N=146). Descriptive statistics were used to analyze the data. The results revealed that the tree map is rated higher than other visualizations in terms of visual appeal, understandability, user friendliness, effectiveness, and usefulness. Keywords—Opinion Mining, Sentiment Analysis, Visual Opinion Mining, Opinion Visualization, Information Visualization

Visualizing MeSH Dataset using Radial Tree Layout
Many display layout techniques were developed for the visualization of hierarchical data set like Cone tree, Treemap, Hyperbolic tree etc. Here, we present a new focus + context (fisheye) technique for visualizing and manipulating large hierarchies. We use the well knows radial tree layout method, in which focused node is placed in center of display, and all other nodes are rendered on appropri...
متن کاملUser perception of 4 hierarchical layouts
Information visualization offers an opportunity to provide quick overviews and support exploration of the information landscape. However, there are many visualization techniques and layouts to choose from and some designs work better than others. The poster presents four hierarchical layouts developed in our FrbrVis prototype to display bibliographic work families and looks at user’s perception...
متن کاملMoireTrees: Visualization and Interaction for Multi-Hierarchical Data
Visualizing hierarchical data is one of the core areas of information visualization. Most of these techniques focus on single hierarchies—hierarchies with a single root element and a single path to each element. In contrast, this work focuses on the browsing of multi-hierarchies—hierarchies with multiple roots or multiple paths per element. A radial focus+context display algorithm and interacti...
متن کاملCupid: Cluster-Based Exploration of Geometry Generators with Parallel Coordinates and Radial Trees
Geometry generators are commonly used in video games and evaluation systems for computer vision to create geometric shapes such as terrains, vegetation or airplanes. The parameters of the generator are often sampled automatically which can lead to many similar or unwanted geometric shapes. In this paper, we propose a novel visual exploration approach that combines the abstract parameter space o...
متن کاملCartesian vs. Radial - A Comparative Evaluation of Two Visualization Tools
Many recently developed information visualization techniques are radial variants of originally Cartesian visualizations. Almost none of these radial variants have been evaluated with respect to their benefits over their original visualizations. In this work we compare a radial and a Cartesian variant of a visualization tool for sequences of transactions in information hierarchies. The Timeline ...
