The AKT Reference Ontology has been developed by the AKT partners
to represent the knowledge used in the CS AKTive Portal testbed, and
consists of several sub-ontologies. These are available in four
and DAML+OIL. Due to the
relative expressiveness of OCML, Ontolingua, OWL and DAML+OIL, there
are aspects of the OCML/Ontolingua versions that are not captured in
the OWL or DAML+OIL versions.
- Support Ontology
- Top level ontology, providing basic definitions used by the portal
ontology, including a simple representation of temporal objects.
- Portal Ontology
- The main ontology, describing people, projects, publications,
geographical data, etc.
- Extensions Ontology
- An ontology of definitions which are in use, but which have not
been reviewed by the AKT partners and agreed for inclusion in the
- RDF Compatibility Ontology
- An ontology of definitions intended to improve compatibility
between the AKT Reference Ontology and RDF(S).
- INCA Ontology
- An ontology which joins the <I-N-C-A> model with the AKT Reference Ontology.
The AKT D3E
website (AKT members only) and the mailing list
provide discussion forums for the ontology.
The data used for the CS AKTive Portal testbed is available in RDF
form from the Hyphen website and
can be browsed on the AKT
Triplestore website. You can also access the AKT Reference
Ontology populated with people and projects from KMi and Southampton in OCML and Ontolingua.
We use the knowledge base stored in the AKT Triplestore to generate
content for this website, most notably the
AKT technology pages, and also to drive
the CS AKTiveSpace
