The Vision
“a configurable platform for infinitely scalable semantic web reasoning”

Why we needThe Large Knowledge Collider
Gartner (May 2007):"By 2012,
70% of public Web pages will have some level of semantic markup, 20% will use more extensive Semantic Web-based ontologies”
• Semantic Technologies at Web Scale?– 20% of 30 billion pages @ 1000 triples per page =
6 trillion triples– 30 billion and 1000 are underestimates,
imagine in 6 years from now… – data-integration and semantic search at web-scale?

Infinitely scalable (1/2)
• by giving up 100% correctness:• trading quality for size• often completeness is not needed• sometimes even correctness is not needed

Semantic Web
A logician’s nightmare
(Dieter Fensel)
Infinitely scalable (2/2)
• by parallelisation:• cluster computing
• wide area distribution “Thinking@home”, “self-computing semantic Web”
• cloud computing? (Amazon now, Google soon?)
“Configurable platform”
“a configurable platform for infinitely scalable semantic web reasoning”
Why “LarKC” ?
• The Large Knowledge Collider
A configurable platform
for experimentation
by others
Why “LarKC” ?
and also:1. a merry, carefree adventure. 2. innocent or good-natured mischief; a prank. 3. something extremely easy to accomplish

FDA white paper Innovation or Stagnation (March 2004):
“developers have no choice but to use the tools of the last century to assess this century's candidate solutions.”
“industry scientists often lack cross-cutting information about anentire product area, or information about techniques that may be used in areas other than theirs”

“Show me any potential liver toxicity associated with the compound’s drug class, target, structure and disease.”
Show me all liver toxicity associated with the target or the pathway.

Use Case: City on-line
• Our cities face many challenges • Urban Computing
is the ICT way to address them • How can we redevelop existing neighborhoods
and business districts to improve the quality of life?
• How can we create more choices in housing, accommodating diverse lifestyles and all income levels?
• How can we reduce traffic congestion yet stay connected?
• How can we include citizens in planning their communities rather than limiting input to only those affected by the next project?
• How can we fund schools, bridges, roads, and clean water while meeting short-term costs of increased security?

Communication
• Early Access Group
• Usage Competition– “we will win if we start to loose”
• We deliver:– software– publications– not “deliverables”
And Finally….
• People are already looking at us:– “Damn... the EU is where all the cool semweb work is
happening these days”– “This kind of infrastructure is exactly the kind of rocket fuel
that is needed at this stage of semweb maturity.”– “The LarKC-inspired workshop on new forms of reasoning for
the semantic web was a conference highlight for me”– “With the current growth rates of RDF on the Web, LarKC
which started out as technologically possible will quickly become operationally necessary”
– “this project really has it all (potentially) in terms of both science and impact”
• “projects already seeking collaboration:OKKAM, MUSING
“This project has the potential
to change the way people work in this area”
