Invited talk Florian Bauer, Operations & IT Director REEEP, at the European Data Forum 2013, 10 April 2013 in Dublin, Ireland: Unleashing climate and energy knowledge with Linked Open Data and consistent terminology

1. The Power of Open Data
Unleashing climate and energy knowledge with Linked Open
Data and consistent terminology (European Data Forum 2013)
Florian Bauer,
Operations & IT Director - REEEP

2. Tagcloud – City of Edmonton (Canada) Workshop

3. The century of big data

4. Why is this not enough ....

5. Data kept in silos ...

6. ... or part of business models ...

7. ... or not digitised

8. ... and is it important
for clean energy?

9. We asked REEEP‘s project implementers ...
Better access to (Government) Data would be important for
the following aspects:
• Policy support
• Business development
• Market assessment/identifying potential for LED
• Investment decisions/demonstrating viability
• Support in project implementation
• Encouraging cross-regional and sectional cooperation
and communication

10. Low emission transportation in Jakarta
Issue: Jakarta - many using fuel inefficient means of transport
such as private cars, motorcycle and taxis
Solution: Implement “trunk/feeder” transportation
system
Impact: Fuel savings of 130 mio l. petrol and 35 mio l.
diesel annually, from passenger shifting to public
transport and fuel conversion from diesel to CNG (1,8
mio tonnes CO2 reduction over 10 years)

11. This project would benefit from open data
• Currently they need to do most of their research on their
own.
• Finding geographic demographic data of the city would be
useful
– how is the population distributed along the bus lines,
– what kind of people,
– where they work etc.
• Such data is potentially available, but is troublesome to get
and is not in the right form.

12. (Linked) Open Data can help us to ...
... avoid replication and provide access to exisiting data
... be able to concentrate on our own expertise
... keep data maintenance to a minimum
... create new knowledge!
This is the power of open data!

14. What is needed ...
• Publish more data
• Publish data in raw, machine readable formats
• Publish data with licences that allow re-use
• Start linking data on a dataset level
• ....

16. Standardisation and consitency is key
Based on our experience in establishing knowledge broker
portals we know:
• There is a strong need to increase consistency when
tagging climate and energy resources
• We need to ensure the consistency of message being
delivered to the public to avoid confusion using terms in
different ways
• This needs standardization of the used categories and
tags

17. Can we support that with an
automated system ?

18. Same

tagged: tagged: PV
photovoltaic
Understanding synonyms & relations?

19. Dealing with disambiguation ...

20. Utilising the power of Linked Open Data

21. A new tool to help with conistent
tagging:
The reegle tagging API (api.reegle.info)

22. Unstructured Data

23. reegle tagging API turns data into knowledge

24. A file is sent …

25. … to the reegle tagging API,
where its content is analyzed.
reegle tagging
API

26. The most relevant terms
are extracted …

27. … as well as
geographic locations

28. For the most relevant
extractions contextual
information is provided
based on the thesaurus

29. Tagging API Example

Have a look on http://api.reegle.info – using the API is free!

increasing our audience

other sites)
