    • The Value of Linked Data in the Age of Big Data Andreas Blumauer CEO & Managing Partner Semantic Web Company
    • About us• Founded as „punkt. netServices“ 1998 in Vienna• Focus: Semantic (web) technologies & search applications – 1st project based on semantic technologies in 2001 – Foundation of Semantic Web School in 2004  Semantic Web Company since 2008 – PoolParty development started in 2007• PoolParty on the market since 2009• Privately held, currently 20 specialists http://www.poolparty.biz/
    • VUCA Worlds Volatility http://www.slideshare.net/dcaron/its-a-vuca-world- See also: Uncertainty Complexity Ambiguityhttp://www.poolparty.biz/
    • A brief history of ‚Data‘ 1990 2012Volatility … The information needed today is different from the information needed tomorrow, next week or next month. Changes come from everywhere: internal strategy changes, competitive pressures, new regulatory requirementsUncertainty … Companies are increasingly drawing on data from outside their organization. They’re pulling together information from supply chain partners, from customers, from social media sites, from websites and public web databases.Complexity … Decision makers are relying on data buried in spreadsheets, in emails, in Access databases and in documents.Ambiguity … Key enterprise data assets are no longer confined to predictably structured transactional databases and data warehouses. http://www.poolparty.biz/
    • Big Data: A DefinitionBig Data is abouttools to examine•large•distributed•unstructured•unrelated and•quickly growingpools of datato create information & knowledge from it.See also: Jeffrey Layton, http://bit.ly/NZb4Yi (Enterprise Storage Forum) http://www.poolparty.biz/
    • Big Data: Another DefinitionBig Data is abouttools that pull together•large•distributed•unstructured•unrelated and•quickly growingpools of datato create an even bigger and less flexible data silowhich creates an even bigger lock-in effect for the customer. http://www.poolparty.biz/
    • Big Data: An example3TIER has conductedfeasibility studiesfor over 650 wind projectson 6 continents,representing over20GW of production potential.In 2011 alone,3TIER conducted risk analysisthat helped secure over $4.1 billion in public and private financing forutility-scale solar projects in the US, India, and Australia.

    • Hunch: The power of correlationHunch’s Taste Graph is the foundation that powers Hunch’s predictions.The graph is fast growing, constantly-improving and built upon a massive data structure. See also: Hunch.com, http://blog.hunch.com/?p=47384 http://www.poolparty.biz/
    • Correlation vs. CausationSleeping with ones shoes on isstrongly correlated with waking upwith a headacheORSleeping with ones shoes on causeswaking up with a headache?Show me all drugs - related to asthma that - are linked to a curated molecular interaction in the literature - where the protein is known to cause inflammatory response http://www.poolparty.biz/
    • Centralized vs. DecentralizedETLcentralized decentralized distributed http://www.poolparty.biz/
    • Example: Querying decentralized systems How many people work at SWC? SWC = Semantic Web Company 20 people work at Semantic Web Company 20 people work at SWC! No central data hub needed!!!http://www.poolparty.biz/
    • How decentralization can contribute to cope with VUCA?Volatility:Higher agility when managed units are smallerUncertainty:Make use of algorithms based on correlationComplexity:Breaking down into smaller modules, crowd-sourcing and self organizationAmbiguity:Better understanding of specialities of sub-domains& local needs http://www.poolparty.biz/
