  7. 7. Department of Parliamentary Services Parliamentary Library and Information Service Linked Data in Libraries • OCLC – 1.2 million resources – 80 million triples • LOC – Subject headings, authority files • British Library – 2.8 million records, 93 billion triples • BIBFRAME • Schema Bib Extend Community Group • LODLAM
  8. 8. Department of Parliamentary Services Parliamentary Library and Information Service Linked Data in Parliament and Government – 6.4 billion triples of open government data
  9. 9. Department of Parliamentary Services Parliamentary Library and Information Service Open Government
  10. 10. Department of Parliamentary Services Parliamentary Library and Information Service Project aims • Is Linked Data useful in a local context • Explore the process of using Linked Data – where do you start? • Being able to interrogate our data in new ways • Use visualisation to gain new insights into data
  11. 11. Department of Parliamentary Services Parliamentary Library and Information Service Databases at Parliament People and Organisations government agencies Documents media releases parliamentary debates (Hansard) newspaper clippings Members of Parliament Media parliamentary papers video and audio clips party policies
  12. 12. Department of Parliamentary Services Parliamentary Library and Information Service Linked Data Workflow Preparation •choose ontology •investigate similar projects Clean and reconcile data •clean data (cluster, facet) •named entity extraction •reconcile with other data Publish •output RDF •store data (files, triple store etc)
  13. 13. Department of Parliamentary Services Parliamentary Library and Information Service Preparation • Investigate similar projects – Don’t reinvent the wheel – Collaborate • Choose an ontology (or build your own) – Linked Data Open Vocabularies (lov.okfn.org)
  14. 14. Department of Parliamentary Services Parliamentary Library and Information Service Popolo Ontology popoloproject.com • developing open government specifications relating to the legislature • prioritizes reuse over novelty • attempts to make it easy to represent real-world data • consensus model – open to contributions (W3C community group, github)
  15. 15. Department of Parliamentary Services Parliamentary Library and Information Service Clean and reconcile data
  16. 16. Department of Parliamentary Services Parliamentary Library and Information Service Clean and reconcile data
  17. 17. Department of Parliamentary Services Parliamentary Library and Information Service Publish • create RDF (Open Refine can do this too) • store data – separate files – embedded in html – Database mapping using D2RQ – triple store
  18. 18. Department of Parliamentary Services Parliamentary Library and Information Service What do we get out of it? • Combined approach – embedded data in catalogue – Fuseki Triple Store • Complex queries using SPARQL: – what have previous speakers being saying about the current issues in parliament? – find all articles about transport that mention members of the Road Safety Committee

  22. 22. Department of Parliamentary Services Parliamentary Library and Information Service Conclusion • The process itself is valuable • Aligning data with standards (Popolo Ontology) • Cleaning and reconciling adds value to data • Databases linked internally • Can now provide Linked Data externally
