For our April Meetup, we are very happy to have Prof. Ben Shneiderman ( from the Department of Computer Science and the Human-Computer Interaction Lab at the University of Maryland, talking about Information Visualization for Knowledge Discovery.

6:30pm -- Networking and Refreshments 7:00pm -- Introduction 7:10pm -- Prof. Shneiderman's presentation and Q&A around 8:30pm -- Adjourn for Data Drinks Abstract

Interactive information visualization tools provide researchers with remarkable capabilities to support discovery. These telescopes for high-dimensional data combine powerful statistical methods with user-controlled interfaces. Users can begin with an overview, zoom in on areas of interest, filter out unwanted items, and then click for details-on-demand. With careful design and efficient algorithms, the dynamic queries approach to data exploration can provide 100msec updates even for million-item visualizations that can represent billion-record databases.

Interactive visualization tools have led to commercial success stories such as Spotfire (, Smart Money's Market Map ( and the Hive Group (, as well as research tools such as TimeSearcher (, developed at UMD for time series data analysis. The integration of statistics with visualizations has been successfully applied to temporal event sequences such as electronic health records (Lifelines2 ( and Lifeflow ( and social network data (SocialAction ( and NodeXL (


Ben Shneiderman ( is a Professor in the Department of Computer Science ( and Founding Director [masked]) of the Human-Computer Interaction Laboratory ( at the University of Maryland. He is a Fellow of the AAAS, ACM, and IEEE, and a Member of the National Academy of Engineering. He is the co-author with Catherine Plaisant of Designing the User Interface: Strategies for Effective Human-Computer Interaction ( (5th ed., 2010). With Stu Card and Jock Mackinlay, he co-authored Readings in Information Visualization: Using Vision to Think (1999). With Ben Bederson he co-authored The Craft of Information Visualization (2003). His book Leonardo’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 ( (2010). Prof. Shneiderman will be happy to sign copies of this book (available at Amazon ( after the presentation.
