Some Benefits of Linked Open Gov’t Data
! Enables applications that allow for ! getting a 360 ° view on an issue ! rapid fact-checking ! cross-referencing and checking of statistical claims (“how to lie with
statistics”) ! increased transparency in public debate ! release of the creative potential of “the crowd”
! Help citizens in their daily life ! to understand their governments better ! find good places to live (little pollution, good schools, close to protected
natural sites…) ! locate public services (administrative offices, public toilets…)
! Brings citizens and government closer together

Conclusion
! Data is fuelling the knowledge-based economy and society ! Global standards enable integration and re-assembling data and apps
! Current applications show-cases mainly single-source datasets ! Next steps: interlinking and cross-referencing data from multiple
sources
! Further research into large-scale semantic data management: multiple modalities (graphs, streams, relations), data quality, privacy, provenance, trust, access rights
! Commercial applications leveraging open gov’t data (in combination with scientific or proprietary data) can bring added value for citizens
