It gets bigger every month
Full Web-style decoupling:
re-usability, independence
• All identifiers are URL's (= on the Web)
– Allows total decoupling of
• data
• vocabulary
• meta-data

For the first time ever,
it is now possible:
to re-use somebody else's knowledge base
• without having to talk to them first
(syntax, semantics)
• without having to make copies
Rapid growth: "billion triple challenge"
(= machine-reason with a billion facts and rules)
• 2006: “where do we get a billion facts from?”
• 2008: “which billion shall we choose!”
What to do when success
is becoming a problem?
The Large Knowledge Collider
a platform for infinitely scalable
reasoning on the data-web
Infinite scalability?
parallelisation
• cluster computing
distribution
• “Thinking@home”,
“self-computing semantic Web”
approximation
• “almost” is often good enough
• gets better with more resources

MaRVIN scales by:

•approximation (sound but incomplete)
•anytime convergence (more complete over time)

“industry scientists often lack cross-cutting information about an
entire product area, or information about techniques that may be
used in areas other than theirs”

Q2
Show me all liver toxicity “Show me all liver toxicity
associated with the target associated with compounds
with similar structure”

LITERATURE
Current NCBI: linking but no inference
Use Case: City on-line
• Our cities face many challenges
• Urban Computing
improve the quality of life
is the ICT way to
address them

Where are people concentrating?
Where is traffic moving?
Is anybody doing this for real?
• OpenCalais:
– enrich text (news items) with semantic meta-data
– recognise people, places, events, organisations,...
– useful for searching, selecting, personalising, aggregating,
summarising, etc
• From early ’09:
– identify “people, places, events, organisations,...”
by linking to the Open Data cloud:

This Web of Data is rapidly taking shape
There are compelling use-cases
Industrial take-up is beginning to happen
We are building new infrastructure
to deal with required scale
