[Matthew Turk]

Just a reminder about this CS Colloquium next Wednesday. Ben Shneiderman is
a huge name in HCI and visualization - I hope you can all make the talk.

Title: Information Visualization for Social Media Network Analysis

Abstract:

Network visualization has been a lively topic for a half century, but 
the intense challenges from many facets of this problem demand diverse 
solutions. While the popular force-directed approaches produce appealing 
presentations, they are often so cluttered that the benefits are limited 
to showing large clusters and disconnected outliers.

Interactive approaches that give users control of node and link 
visibility enable them to make more fine-grained analyses that lead to 
important insights about relationships among nodes or the presence of 
exceptional nodes and links. Another important task is to spot the 
absence of expected nodes and links. One strategy is coordinating 
network visualizations with statistical measures from graph theory and 
social network analysis to give users interactive control of ranking, 
filtering and clustering (http://www.cs.umd.edu/hcil/socialaction). A 
second strategy involves a novel layout technique to arrange node 
positions according to their attributes in stable yet comprehensible 
semantic substrates (http://www.cs.umd.edu/hcil/nvss). These novel 
strategies have influenced the design of the novel network visualization 
tool that is embedded in Excel: Network Overview for Discovery and 
Exploration in Excel (NodeXL:http://www.codeplex.com/nodexl ). The main 
application has been social media networks extracted from Twitter, 
Facebook, Flickr, or YouTube usage patterns.

Bio:

Ben Shneiderman is a Professor in the Department of Computer Science and 
Founding Director (1983-2000) of the Human-Computer Interaction 
Laboratory (http://www.cs.umd.edu/hcil/) at the University of Maryland. 
He is a Fellow of the AAAS, ACM, and IEEE, and a Member of the National 
Academy of Engineering.

Prof. Shneiderman is the co-author with Catherine Plaisant of Designing 
the User Interface: Strategies for Effective Human-Computer Interaction 
(5th ed., 2010, http://www.awl.com/DTUI/). With Stu Card and Jock 
Mackinlay, he co-authored Readings in Information Visualization: Using 
Vision to Think (1999). His bookLeonardo's Laptop appeared in October 
2002 (MIT Press) and won the IEEE book award for Distinguished Literary 
Contribution. His latest book, with Derek Hansen and Marc Smith, is 
Analyzing Social Media Networks with NodeXL (www.codeplex.com/nodexl, 
2010). This is available for sale on Amazon.com, and Ben would be happy 
to sign copies of the book after his talk.
