Government Data Sharing January 1, 2009 “ Openness will strengthen our democracy and promote efficiency and effectiveness in Government.” --- President Obama Putting Govt Data online- Data.gov.uk beta May 21, 2009 January 19, 2010 data.gov.uk online May 21, 2010 data.gov online data.gov relaunch with semantic web featured June30,2009 December 8, 2009 “ Open Government Directive ” released 2009 2010 … 57 Data Sets ~6000 Data Set ~2000 Data Sets >305,000 Data Sets
Important to the citizens: eg. Education Data.gov.uk RPI NYS demos
Moving data.gov to linked data (UK) ,[object Object],[object Object]
Moving data.gov to linked data (US) ,[object Object],[object Object],[object Object],[object Object]
[object Object],More than 50 of these at http://logd.tw.rpi.edu (and lots more at data.gov.uk)
Data.gov + epa.gov
 
Adding some Web magic Web Analytics Social Data Networks External Links
Linking GDP of the US and China GDP of China (Billion Chinese Yuan ) GDP of the US (Billion Dollar) [Temporal Mashup] bea.gov + federalreserve.gov +stats.gov.cn
Linking GDP of the US and China GDP of China (Billion Chinese Yuan ) GDP of the US (Billion Dollar) [Temporal Mashup] bea.gov + federalreserve.gov +stats.gov.cn This mashup was built in less than 4 hours – including conversion of data, web interface, and visualization!
Govt systems can use linked data web for context Datasets: acres burned, and agency budgets Dbpedia: wikipedia descriptions of major US fires
Integrate with Social media
Combining data from different data sharing sites
RPI workflow enhances raw RDF w/useful URIs derive derive create derive revision Convert Access Enhance Version SemDiff
http://logd.tw.rpi.edu demos, tutorials, RDF-ized datasets, and more
 
Government Data in the linked open data cloud http://linkeddata.org/ Government Data is currently over ½ the cloud in size (~17B triples), 10s of thousands of links to other data (within and without)
URI design ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
