Ontology Id representation in RTS

Shahid Manzoor — Wed, 30 May 2007 16:53:40 -0000

The ontology id in the RT templates assertions represents that the class or relation ids in the assertions belongs to the ontology. The ontology id can be represented by an IUI for a particular version of the ontology.

The ontology id representation as IUI needs to be implemented in the RTS.

Universals existance check in the ontology systems

Shahid Manzoor — Wed, 30 May 2007 14:57:26 -0000

At the time adding assertions, i.e PtoU or PtoCo, PtoLackU and PtoP, the implementations of the RTRepository class may have to validate that a ontology class or a relation or a concept code exist in their ontology systems.

OntologyConnector stores false assertions in its cache

Shahid Manzoor — Wed, 30 May 2007 13:36:30 -0000

OntologyConnector is a base class which provides abstract methods to connect with the external ontology systems. Its sub classes implements the abstract methods specific for a particular ontology system.
The queries made to the external systems via OntologyConnector is as:

u1 subClassOf u2
u1 partOf u2
u2 hasPart u1

The OntologyConnector class also maintains a cache for all the inference computations queries made to the external ontology systems for the future use to search locally for before sending requests to the external ontology systems.

If the OntologyConnector specialize class fails to report the inference computations result made to the external ontology systems, then, the ontology connector assumes that the assertion query such as (Left thumb partOf Left hand) is false, and store the false assertion in the cache.

In such case where the specialize fails to get results from the external systems then the ontology connector should not store those queries in the cache.
