Visualizing Social Media Content with SentenTree

Mengdie Hu, Krist Wongsuphasawat, John Stasko
2017 IEEE Transactions on Visualization and Computer Graphics  
The technique employs design ideas from word clouds and the Word Tree, but overcomes a number of limitations of both those visualizations.  ...  Fig. 1: Part of a SentenTree visualization of a collection of 189,450 tweets (108,702 unique) posted in a 15 minute time window around the first goal of the opening game of the 2014 Soccer World Cup.  ...  In the next two sections we review two major classes of visualizations of textual content: word cloud-related visualizations and text structure visualizations.  ...

Uncovering Representative Groups in Multidimensional Projections

P. Joia, F. Petronetto, L.G. Nonato
2015 Computer graphics forum (Print)  
Multidimensional projection-based visualization methods typically rely on clustering and attribute selection mechanisms to enable visual analysis of multidimensional data.  ...  In this work we propose a novel multidimensional projection-based visualization technique that relies on representative instances to define clusters in the visual space.  ...  Acknowledgments We would like to thank the anonymous reviewers and the Brazilian funding agencies FAPESP (#2013/19760-5, #2011/22749-8 and #2010/07367-9) and CNPq (#302643/2013-3).  ...
