  1. Employing Google Refine to Publish Linked Data Fadi Maali and Richard Cyganiak

  2. Road map • Self-Service Linked Government Data • Google Refine • RDF Export Extension • RDF Reconciliation Extension

  3. We need government data as Linked Data not just Raw Data ….aha, and of a good quality!

  4. Raw data catalogue, data.gov

  5. We want governments to provide Linked Data not just Raw Data… and of good quality TIME MONEY SKILLS

  6. From raw data to Linked Data DIY

  7. DIY Recipe Tool support to select datasets of interest and put them into RDF Publishers provide RDF representation of their catalogues User shares the RDF data

  8. DIY Recipe Publishers provide RDF representation of their catalogues Tool support to select datasets of interest and put them into RDF User shares the RDF data dcat

  9. DIY Recipe Tool support to select datasets of interest and put them into RDF Publishers provide RDF representation of their catalogues User shares the RDF data dcat Google Refine + RDF export extension + RDF reconciliation extension

  10. DIY Recipe User shares the RDF data Publishers provide RDF representation of their catalogues Tool support to select datasets of interest and put them into RDF dcat Google Refine Share RDF data along with the conversion process description + RDF export extension + RDF reconciliation extension Provenance & Reproducibility

  11. Road map • Self-Service Linked Government Data • Google Refine • RDF Export Extension • RDF Reconciliation Extension

  12. Google Refine Google Refine is a power tool for working with messy data, cleaning it up, transforming it from one format into another, extending it with web services, and linking it to databases like Freebase* • Desktop application that a user interacts with using a web browser • Open Source (New BSD License) • Extensible *http://code.google.com/p/google-refine/
