3. Data is not what we want or is it?

4. What we need are insights
and actionable-knowledge

5. Diffusion of innovation

IoT

6. Problem #1
Data: We seem to have lots of it…
Real World Data: it is always difficult to get
(silos, format, privacy, business interests or
lack of interest!...)

7. Problem #2
Data: interoperability and metadata
frameworks…
Real World Data: there are solutions for
service based (Restful) access, meta-
data/semantic representation frameworks
(W3C SSN, HyperCat,…) but none of them
are widely adapted.

8. Problem #3
Data: quality, reliability…
Real World Data: data can be noisy, crowed
source data can be inaccurate,
contradictory, delay in accessing/processing
the data…

9. Problem #4
Data: having too much data and using
analytics tools alone won’t solve the
problem…
Real World Data: in addition to the HPC
issues, we need new methods/solutions that
can provide real-time analysis of dynamic,
variable quality and multi-modal streams…

10. Problem #5
Data: abstraction, discovering the
associations…
Real World Data: co-occurrence vs.
causation; we need hypothesis, background
knowledge,…
After all data is not what we are really
after…

11. We need more linked open data

12. (near) real-time
linked open data
Streams
Sometimes it’s even better if we have:

Sufficient background knowledge
or even better than that if we have:

Challenges and opportunities
− Providing infrastructure
− Publishing, sharing, and access solutions on a global scale
− Heterogeneity and interoperability at different layers
− Indexing, query and discovery (data and resources)
− Aggregation, integration and fusion
− Trust, privacy and security
− Data analytics and creating actionable knowledge
− Integration into services and applications in e-health, the public
sector, retail, manufacturing and personalised apps.
− Mobile apps, location-based services, monitoring control etc.
− New business models
