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, ...
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 ...
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 ...
Lexichrome: Text Construction and Lexical Discovery with Word-Color Associations Using Interactive Visualization
(ACM, 2020-07-03)
Based on word-color associations from a comprehensive, crowdsourced lexicon, we present Lexichrome: a web application that explores the popular perception of relationships between English words and eleven basic color terms ...
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 ...
A "Communication Skills for Computer Scientists" Course
(ACM, 2009-07)
This paper describes "Communication Skills for Computer Scientists," a novel undergraduate course at the University of Toronto. We describe in detail the three major instructional streams of the course: writing, speaking, ...
Webcasting Made Interactive: Persistent Chat for Text Dialogue During and About Learning Events
(Springer, 2007)
This paper presents a “persistent chat” extension to the ePresence Interactive Media webcasting infrastructure to support real-time commenting on and discussing of issues that arise during a learning event, followed by ...
Approaching Humanities Questions Using Slow Visual Search Interfaces
(2021-06-01)
In this paper we discuss a visual search system that was designed and implemented for humanities scholars to ask questions of large document corpora. The system allows searches to be specified through traditional search, ...
