Last week we were honored to have had Dr. Ben Shneiderman, Professor of Computer Science and Founding Director of the Human-Computer Interaction Laboratory at the University of Maryland, present a Big Thinkers talk at Yahoo entitled, "Information Visualization for Knowledge Discovery: Big Insights from Big Data." During his presentation, Dr. Shneiderman focused on the importance of visualization tools in answering Big Data questions and solving Big Data problems. Shneiderman enthusiastically stated that "visualization is a way of engaging people," and that "visualizations give you answers to questions you didn't know you had."
Professor Shneiderman also covered his "8 Golden Rules of Data Science":
- Choose actionable problems and compelling theories
- Open your mind: domain experts and statisticians
- If you don't have questions, you're not ready
- Clean, clean, clean... your data (gently on the screen)
- Know thy data: ranges, patterns, clusters, gaps, outliers, missing values, uncertainty
- Evaluate your efficacy, refine your theory
- Take responsibility, reveal your failures
- Work is complex, proceed with humility
The event was broadcast live on our labs.yahoo.com
homepage and viewers had the opportunity to ask questions and comment on our Twitter stream @YahooLabs

Interactive information visualization tools provide researchers with remarkable capabilities to support discovery from Big Data resources. Users can begin with an overview, zoom in on areas of interest, filter out unwanted items, and then click for details-on-demand. The Big Data initiatives and commercial success stories such as Spotfire and Tableau, plus widespread use by prominent sites such as The New York Times
have made visualization a key technology.
The central theme is the integration of statistics with visualization as applied for time series data, temporal event sequences such as electronic health records (www.cs.umd.edu/hcil/eventflow
), and social network data (www.codeplex.com/nodexl
). By temporal pattern search & replace and network motif simplification, complex data streams can be analyzed to find meaningful patterns and important exceptions. The talk closes with 8 Golden Rules for Big Data.
