Progressive Learning of Topic Modeling Parameters: A Visual Analytics Framework
(IEEE, 2017-08-29)
Topic modeling algorithms are widely used to analyze the thematic composition of text corpora but remain difficult to interpret and adjust. Addressing these limitations, we present a modular visual analytics framework, ...
Design by Immersion: A Transdisciplinary Approach to Problem-Driven Visualizations
(IEEE, 2019-08-26)
While previous work exists on how to conduct and disseminate insights from problem-driven visualization projects and design studies, the literature does not address how to accomplish these goals in transdisciplinary teams ...
TandemTable: Supporting Conversations and Language Learning Using a Multi-Touch Digital Table
(Association for Computing Machinery, 2015-06-03)
We present TandemTable, a multi-touch tabletop system designed to break down communication barriers between partners, with a special focus on supporting those who are learning languages. The design was guided by a grounding ...
Using Visual Analytics of Heart Rate Variation to Aid in Diagnostics
(CEUR Workshop Proceedings, 2016-06-07)
We present an interactive visualization tool for exploring RR interval data (the time between consecutive heart beats) to support diagnostics. An RR interval sequence diagram allows us to reduce hours of data into a general ...
Visual Analytics for Topic Model Optimization based on User-Steerable Speculative Execution
(IEEE, 2018-09-18)
To effectively assess the potential consequences of human interventions in model-driven analytics systems, we establish the concept of speculative execution as a visual analytics paradigm for creating user-steerable preview ...
Visualization and the Digital Humanities: Moving Toward Stronger Collaborations
(IEEE, 2018-12-01)
For the past two years, researchers from the visualization community and the digital humanities have come together at the IEEE VIS conference to discuss how both disciplines can work together to push research goals in their ...
Textension: Digitally Augmenting Document Spaces in Analog Texts
(DHQ, 2019)
In this paper, we present a system that automatically adds visualizations and natural language processing applications to analog texts, using any web-based device with a camera. After taking a picture of a particular page ...
Critical InfoVis: Exploring the Politics of Visualization
(ACM, 2013-04-27)
As information visualization is increasingly used to raise awareness about social issues, difficult questions arise about the power of visualization. So far the research community has not given sufficient thought to how ...
Perceptual Biases in Font Size as a Data Encoding
(IEEE, 2017-07-04)
Many visualizations, including word clouds, cartographic labels, and word trees, encode data within the sizes of fonts. While font size can be an intuitive dimension for the viewer, using it as an encoding can introduce ...
Saliency Deficit and Motion Outlier Detection in Animated Scatterplots
(Association for Computing Machinery, 2019-05-04)
We report the results of a crowdsourced experiment that measured the accuracy of motion outlier detection in multivariate, animated scatterplots. The targets were outliers either in speed or direction of motion, and were ...
