ORO - The OpenRobots Common Sense Ontology
This page give basic information to get the latest version of the OpenRobots Common Sense Ontology. This ontology, largely based on OpenCyc upper ontology, is the result of a joint work by the French LAAS-CNRS and the German TUM-IAS labs.
The OpenRobots Common Sense ontology is a key component of the ORO project.
It shares most of its concepts with the KnowRob ontology.
Summary

General background on ontologies
To start with the concept of ontologies:
Wikipedia: Ontology
The presentation I did as introduction to ontologies in the lab in December 2008 (in French)
Accessing it online
The OpenRobots Common Sense Ontology URI is http://kb.openrobots.org/
You can access and refer to it there.
Getting the latest version
Currently, to get the latest version of the common sense ontology, you need to clone the main GIT repository:
> git clone http://trac.laas.fr/git/robots/oro.git
The ontology is NOT stabilized yet, and actually is subject to important on-going changes. You are more than welcome to modify it!
If you don't want to use GIT, a (not very recent) snapshot is available: [[http://www.laas.fr/~slemaign/oro/oro-20100112.tar.gz| oro-20100112.tar.gz]]
Extract it somewhere and change the server configuration file (etc/oro-server/oro-server.conf) to point to it.
Visualising and editing ontologies
|
I recommend to install 'Protege', the most famous software to create and edit ontologies.
Download it here (version 4): http://protege.stanford.edu/download/registered.html
Quick online tool to browse the ontology :
OWLSight: http://pellet.owldl.com/owlsight/
Protege should be enough for most of your needs. If you want more:
- A lot of plugins for Protege are available for visualisation. Check Protege website.
'Growl': a stand-alone (or Protege-pluggable) visualisation tool for OWL ontologies, with a nice dynamic layout engine.
Download it here: http://www.uvm.edu/~skrivov/growl/ (I recommend the “old” stand-alone package)
Another useful tool, if you are interested in Description Logics reasonning: Complexity of reasoning in Description Logics
A very complete list of tools to manage, access, visualize, play with ontologies is maintened at W3C: http://esw.w3.org/topic/SemanticWebTools
