3 Where do the data come from? Why do we have a national initiative?
4 The Big Data Landscape I: Big Science Science gathers data at an ever-increasing rate across all scales and complexities of natural phenomena Sloan Digital Sky Survey in 2000 collected more data in its 1 st few weeks than had been amassed in the entire history of astronomy Within a decade, over 140 terabytes of information collected Large Hadron Collider generates scores of petabytes a year The proposed Large Synoptic Survey Telescope (3.3 gigapixel digital camera) will generate 40 terabytes of data nightly By 2015, the world will generate the equivalent of approximately 93 million Libraries of Congress

7 Communications Volume & Traffic Diversity VoIP Video Twitter Broadband 663M registered Skype users in Represents 20% of long distance minutes world-wide. If Skype were a carrier, it would be the 3rd largest in the world (behind China Mobile and Vodaphone). Largest provider of cross-border communication. Recent estimates as high as 60% of internet traffic is video and music sharing; 35 hours of new videos are uploaded every minute in 2011; 2 billion views per day. Currently 175 million registered users. 20% of global internet users have residential broadband; d; 68% in US subscribe be to broadband. d Mobile 5.3 billion mobile phone subscribers; 85% of new handsets will be able to access the mobile web; 1 in 5 has access to fast service, 3G or better; IM, MMS, SMS expected to exceed 10 trillion message by 2013.
8 The Big Data Landscape IV: The Long Tail of fscience Hundreds of thousands of scientists and engineers work individually or in small, distributed, disconnected groups all generating data that collectively represent an enormous, largely untapped scientific resource From running simulations, experiments, etc. Making heterogeneous data across many areas of science more homogeneous could give way to breakthroughs across all areas of science and engineering Estimated 40 exabytes of unique new information generated worldwide in 2010 Only 5% of the information created is structured, however, in a standard format of words or numbers; the rest are unstructured text, voice, images, etc.

13 The Age of Data: From Data to Knowledge to Action Data-driven discovery is revolutionizing i i scientific exploration and engineering innovations Automatic extraction of new knowledge about the physical, biological and cyber world continues to accelerate Multi-cores, concurrent and parallel algorithms, virtualization and advanced server architectures will enable data mining and machine learning, and discovery and visualization of Big Data

15 From Data to Knowledge to Action Researchers seek to fundamentally transform understanding of spinning giants The task involves assembling data from more storm variables-such as updraft, downdraft and vorticity or g p, y regions of spin--than what can be observed from ground tornado chasers or even actually produced in the atmosphere. For example, researchers need to better understand how changes in wind direction with height cause the updrafts in a storm to rotate, preceding the formation of a tornado. To solve the quandary, Amy McGovern, an associate professor in OU's School of Computer Science, and her team create tornado models with super computers that can process vast amounts of data. McGovern and her colleagues use the models to analyze how storm variables interact in order to identify tornadic and nontornadic storms.
16 Examples of Research Challenges More data are being collected than we can store Analyze the data as it becomes available Decide what to archive and what to discard Many data sets are too large to download Analyze the data wherever it resides Many data sets are too poorly organized to be usable Better organize and retrieve data Many data sets are heterogeneous in type, structure, semantics, organization, granularity, accessibility Integrate and customize access to federate data Utility of data is limited by our ability to interpret and use it Extract and visualize actionable knowledge Evaluate results Large and linked datasets may be exploited to identify individuals Design management and analysis with built-in i privacy preserving characteristics
17 A National Imperative PCAST calls on the Federal government to increase R&D investments for collecting, storing, preserving, managing, g, analyzing, and sharing the increasing quantities of data. Furthermore, PCAST observed that the potential to gain new insights to move from data to knowledge to action has tremendous potential to transform all areas of national priority.

32 A Complex Policy Setting Researchers want data. Public policy requires access to data. Public policy also requires protection of privacy and intellectual property and other sensitive information. Much more to be done: Policy on data management and data access.
33 Data Privacy Never more important than today However, not all data contain people s identities (as in data landscape III) Not a Big Brother scenario Government (NSF) invests in privacy research Values in design research community: Identity cloaking, anonymization Do-not-track cookie management Obfuscation, blurring Privacy preserving data mining, search, payment Just-in-time crypto Secure data distribution. Privacy in technology; privacy inspired technology
34 Opportunities for the Future Our investments in research and education have already returned exceptional dividends to the Nation. Many of tomorrow s breakthroughs will occur as a result of new techniques and technologies for advancing Big Data science and engineering. In turn, Big Data scientific discovery and technological innovation are at the core of our response to national and societal challenges from environment, energy, transportation, sustainability, and healthcare to cyber security and national defense.
