Fig. 3 A class hierarchy of university ontology
Fig. 4 Entity, agent and
activity relationship to super
class thing
Figure 5 provided below states that a university publishes a hard-bound journal
and publishes an e-journal both of which are an Entity. The e-journal is an alteration
of the university journal. The e-journal has been created by the Activity- creation of
university e-journal by Agent Vijay.
The relationship between Agent and Activity has been mentioned using the wasAssociatedby property and the relationship between the university journal and the ejournal has been mentioned by the provenance assertion named alternateOf . Further,
the relationship that specifies that the Activity creation of a university journal is an
individual/instance of class Entity is specified by the relationship has individual. The
figure provided below shows the asserted and inferred model of the ontology.
The assertion in Fig. 6 states that e-journal is an alternate of university journal. The
relationship between the two is implicitly defined by the assertion alternateOf and
the reasoner explicitly evaluates the validity of the property. Figure 7 demonstrates
that a valid identifier in terms of URI is associated with every instance of Entity,
Activity, and Agent, which enables it to be referenced on the semantic ecosystems.
Creation of an Entity the university e-journal takes place by an Agent instance
Vijay through the Activity creation of the university e-journal therefore we are bound
to specify the relationship through the assertion wasAssociatedWith.
Figure 8 highlights the aspects of a provenance model.
