What is Visual Analytics? Jim Thomas AAAS Fellow, PNNL Fellow Director National Visualization and Analytics Center Jim Thomas 9/16/2008
What is Visual Analytics? • Third Wave: Knowledge based society Visual analytics enables the creation of knowledge • Definitions • Motivation behind the need for science of visual analytics • What Visual Analytics is and is not: examples • Establishment of VAC partnerships from basic sciences to deployed missions • Transition to DHS Perspectives: Video 2
The Third Wave Wealth System • “Third Wave Wealth system is increasingly based on serving, thinking, knowing and experiencing.” transdisciplinary science • Revolutionary Wealth: Alvin and Heidi Toffler, Alfred Knopf publisher 2006, authors of Future Shock and The Third Wave • Knowledge based economy: • "The new production of knowledge: The dynamics of science and research in contemporary societies" By Michael Gibbons, Camille Limoges, Helga Nowotny, Simon Schwartzman, Peter Scott, and Martin Trow • "Re-Thinking Science: Knowledge and the Public in a Age of Uncertainty" By Helga Nowotny, Peter Scott, and Michael Gibbons • Data – Information – Knowledge - Wisdom 3
Visual Analytics Definition Congress: Visual analytics provides the last 12 inches between the masses of information and the human mind to make decisions Science: Visual analytics is the science of analytical reasoning facilitated by interactive visual interfaces
History of Graphics and Visualization • 70s to 80s • CAD/CAM Manufacturing, cars, planes, and chips • 3D, education, animation, medicine, etc. • 90s to 2000s • Information visualization • Web and Virtual environments • 80s to 90s • Scientific visualization • Realism, entertainment • 2000s to 2010s • Visual Analytics • Visual/audio appliances
Selected Societal Drivers and Observations • Scale of Things to Come: • Information: • In 2002, recorded media and electronic information flows generated about 22 exabytes (1018) of information • In 2006, the amount of digital information created, captured, and replicated was 161 EB • In 2010, the amount of information added annually to the digital universe will be about 988 EB (almost 1 ZB) • A Forecast of Worldwide Information Growth Through 2010: IDC • National Open Source Enterprise - Intelligence Community Directive No. 301, July 11, 2006 • UC Berkeley School of Information Management and Systems: Now much Information
Why Must Change • Scale of Things to Come: • Information: • Drivers of Digital Universe: • 70% of the Universe is being produced by individuals • Organizations (businesses, agencies, governments, universities) produce 30% • Wal-Mart has a database of 0.5 PB; it captures 30,000,000 transactions/day • The growth is uneven • Today the United States accounts for 41% of the Universe; by 2010, the Asia Pacific region will be growing 40% faster than any of the other regions
Why Must Change • Scale of Things to Come: • Information: • Drivers of Digital Universe: • Kinds of Data: • About 2 GB of digital information is being produced per person per year • 95% of the Digital Universe’s information is unstructured • 25% of the digital information produced by 2010 will be images • By 2010, the number of e-mailboxes will reach 2 billion • The users will send 28 trillion e-mails/year, totaling about 6 EB of data
Why Must Change • Scale of Things to Come: • Information: • Drivers of Digital Universe: • Kinds of Data: • Interaction: • Today's interaction designed for point and click on individual items, groups(folders), and lists • Today's interaction assumes user knows subject, concepts within information spaces, and can articulate what they want • Today's interaction assumes data and interconnecting relationships are static in meaning over time • Today's interaction is one way initiated • Today’s interaction (WIMP) designed over 30 years ago
Observations on Complexity and Uncertainty • Disorganized Complexity almost always comes with unstructured data, 95% of data • Organized Complexity1: one could conceivably model or simulate, such as city neighborhood as a living mechanism • Disorganized Complexity1: seemingly random collections, unknown relationships, unknown forces • With Unstructured data comes a significant, amount of uncertainty • Uncertainty2: The lack of certainty, A state of having limited knowledge where it is impossible to exactly describe existing state or future outcome, more than one possible outcome. • Vagueness or ambiguity are sometimes described as "second order uncertainty", where there is uncertainty even about the definitions of uncertain states or outcomes. Must enable and rely on human judgment • Weaver, Warren (1948), “ Science and Complexity”. American Scientist 36:536 • Tannert C, Elvers HD, Jandrig B (2007). "The ethics of uncertainty. In the light of possible dangers, research becomes a moral duty." EMBO Rep. 8 (10): 892-6.
Critical Thinking* “…the quality of our life and that of what we produce, make, or build depends precisely on the quality of our thoughts.” Purpose of the Thinking Elements of thought: Points of View Implications & Consequences Question at Issue Assumptions Information Interpretation And Inference Concepts * Foundations of Critical Thinking www.criticalthinking.org
Example Heuer’s Central Ideas • “Tools and techniques that gear the analyst’s mind to apply higher levels of critical thinking can substantially improve analysis… structuring information, challenging assumptions, and exploring alternative interpretations.”
