Health Datapalooza IV: June 3rd-4th, 2013 Open Government Data Moderator: George Thomas, Enterprise Architect, Office of the Chief Information Officer (CIO), U.S. Department of Health & Human Services Speakers: John Erickson, Director of Web Science Operations, Tetherless Word Constellation, Rensselaer Polytechnic Institute James P. McCusker, Ph.D Student, Dept. of Computer Science, Rensselaer Polytechnic Institute Mark Musen, Professor, Stanford University and Principal Investigator, National Center for Biomedical Ontologies Natasha Noy, Senior Research Scientist, Stanford University and Executive Committee Member, National Center for Biomedical Ontologies Michael Pendleton, Linked Open Data Manager, US Environmental Protection Agency The session will open with an overview of trends affecting open data sharing, including ‘broad data’ challenges that emerge when application developers have millions of open government datasets available. We will explore issues of web-scale data discovery, rapid and potentially ad hoc integration, visualization, and analysis of partially modeled datasets as well as issues arising from combining different data use policies. We will present emerging solution standards and transitioning academic technologies, including innovative work conducted by the ‘Watson’ research group at Rensselaer Polytechnic Institute on using Watson as a ‘data advisor’. Panelists will synthesize session topics including optimal steps toward an open health knowledge graph facilitating ‘data liquidity’ (as defined by the ability to easily combine and refine data from disparate publishers). Panelists will discuss enabling the implementation of effective ‘lifting schemes’ by leveraging ‘collaboration without coordination’ processes to produce efficient data access techniques that drive innovative new application development tools, products, and services.

Digital Government Strategy
Provide open data in structured formats; exposed so
it is accessible for meaningful use beyond its system
of origin. Data should be machine-
readable, platform independent, and available
without restriction. Ensure metadata is included.

16. Linked Data Supported by W3C
(Extension anticipated)

17. Uptake By Other Governments

18. Emergence of Environmental Linked Data Apps

19. Combine EPA Linked Data with Other Linked Data
