KIM is awesome!

KIM Platfrom

• Semantic annotation of text – automatic ontology population – open-domain dynamic semantic annotation of unstructured and semi-

structured content for Semantic Web and KM applications

• Indexing and retrieval (semantically-enabled and IE-enhanced search technology)

• Query and exploration of formal knowledge

• Co-occurrence tracking and ranking of entities

• Entity popularity timelines analysis

KIM platform #5April 2010

KIM Fact Sheet

• Runs on many platforms – Officially on Sun/Oracle JVM on Linux, Windows– Reported to run on IBM Java 1.6 on PS3, also on x86 OpenSolaris

• Can be used programmatically

• KIM runs as a service and it is remotely accessible– through Java RMI– through Web-services from .NET or other– JMS starting from version KIM 3.0

• Can integrate processing resources from GATE

• Proton ontology is kind of dependency

The semantic data path

GATE

Ontology aware annotations

SAR

OWLIM

NLP (Natural Language Processing) phase

Not just annoations, but annotations that have URIs from the Ontology provided

If you have URIs for everything, then nothing stops us from generating RDF

If we have RDF then we need to store it and merge it with the one previously available

Instance Generator

Generate URIs for the new entities and relations

Semantic Repository - Instance URI

Instance generator

Instance URI

Found

OWLIM

Some entities are identified directly and

we know their instance URI and class in

advance

Benefiting form the work of the gazetteer and using rules more entities are detected

Instances of the same entity are merged: ex:

“Apple” and “Apple Inc.”

Add/Merge RDF

An algorithm is used to generate URIs.

Deployment

• How to start KIM

• How to configure KIM

• How to import/populate documents in KIM– Populator tool– KimGate

• Documentation location: – http://ontotext.com/kim/doc/sys-doc/HomePage.html

• KIM 3.0– No ORACLE dependency for some of the functionality– Pluggable component architecture - this will allow KIM to start without loading

semantic annotation service or document repository– Integration with latest GATE 5.1/5.2

KIM platform #13April 2010

Cool stuff

• How we do co-occurrence in a single document?– Using a slightly modified GATE Othomatcher processing resource

• How we do co-occurrence in many documents?– Using Instance URIs and OWLIM

• Optimizations - parallel annotation– Using multiple GATE pipelines
