2. Agenda
• Motivation
• Based on a real story
• Why (L) Open data
• Transformation “Triplication to 5 star”
• Proof of Concept “Demonstrator”
• Tools and Next Steps

3. Moving from Morges to Biel
• Which is the best neighborhood to live If I want to have:
• A Child care center
• Bilingual school
• Handicapped parking for visiting friends
• Closest from work
• What are the taxes in Biel compared with Morges?
• How much are the housing prices compared with Morges?
Morges
Biel

4. Child care centers

5. Child care centers
l 7 child care centers on google maps
l 17 child care centers on pdf from biel-bienne.ch

6. Elementary Schools

7. Elementary Schools
l 1 bilingual elementary school on google maps
l 9 elementary schools in biel-bienne.ch ? bilingual

8. Community Taxes

9. Community Taxes
l Found 2011 statistics for Families having a 80,000 annual revenue
l Manually compared Morges (11.4%) vs Bienne (12.2%)

10. Data exists but ...
l In several of different places
l Google
l Biel-Bienne.ch
l Homegate.ch
l www.bfs.admin.ch
l Most in a format that cannot be reused, or needs to be adapted
l Google maps
l Documents (html, pdf, xls)
l At different granularity levels
l Data ownership

Excerpt of Reasons
• Sharing of Data
• Transparency
• Meet regulatory compliance
• Initiate Innovation (and new economy)
• Build new Apps that help people (Hackathons)
• Engagement (Collaboration)

15. Transformation “Triplication”
Do you think people from
the city understand all
the technical jargon?

16. Creating Linked Open Data
• Getting the data
• Modeling your data – schema
• Transforming your data
• Create applications

17. Data Sources
• Local government data Biel/Bienne website - 1 star data
• Marketing, Sports, Events, etc.
• Most of data not open or in PDF
• Swiss statistics – 4 stars data
• Open data in excel
• Moving to 5 stars
• Web data –five stars data
• Open street maps
• Wikipedia
• 295 open datasets in 2011

18. Transforming your data
Free and open source tools:
• LOD2 stack
• D2R[Q]
• LIMES
• …
• Biel/Bienne use case : LODGRefine
• Extension of Google Refine for LOD
• Import data from cvs, xls
• Clean/Refine your data
• Associate data with chosen vocabularies
• Link your data with other open datasets
• Export to RDF

19. Triplication Process
Vocabulary
(Ontology,
schema)
Refine,
Clean,
Link
Insert,
Expose
RDF
SPARQL
Endpoint
Tools:
OpenRefine
RDF Refine (DERI)
Google Refine (old)
Publish the Data Catalogue
We use “OntoQUAD”
(…there are many
RDF graph databases)

20. Ontology Model based on schema.org

21. Clean data and link to ontology
http://openrefine.org/
http://refine.deri.ie/
LOD2 stack
ZRH, Zürich, Zuerich, Zurich

22. LODGRefine

23. Summary I
q Collect data from Web and store in XLS (CSV)
q Model Ontology
q Clean data using OpenRefine / LODRefine
q Connect CSV colons to RDF(ontology)
and Reconcile (link to other data) “5 star”
q Export the RDF
q Load RDF to Graph database (OntoQUAD)
and publish the data as SPARQL endpoint
and/or on a datacatalogue

24. Orchestration of Linked (O) Data
Using as many as possible Open Source Tools
- From the LOD2 stack (LIMES) “EU FP7 project”
- D2RQ from FU Berlin and DERI (and others)
- NLP engines
- RDF Store (OntoQUAD, Virtuoso, etc)
OntoQUAD – BSBM May 2013

31. Proof of Concept “Demonstrator”
Biel/Bienne demo of what can be achieved
with open linked data http://citydemo.ontos.com/#
• Which is the best neighborhood to live If I want to
have:
• A Child care center
• Bilingual school
• Handicapped parking for visiting friends …
• How much are the housing prices compared with
Morges?
