Triples and Graph

The base element of the

RDF model is the triple:

• a resource (the subject)

• inks (the predicate)

• another resource (the

object) object)

A resource <subject> has a

property <predicate>

valued by <object>.

<subject> <predicate> <object>

OWL

(Ontology Web Language)

• OWL-Lite– Support simple classification, allows only cardinalities

(member count) of 1 and 0 and only minimal constraints.

• OWL-DL (Descriptive Language)• OWL-DL (Descriptive Language)– Supports more complex ontologies, but with

guarantees, such as processing finishing in finite time, restricting elements to be one type.

• OWL-Full– Full support for maximum freedom of RDF, with no

computational guarantees.

Events & ActionsActions and Events in Interval Temporal Logic, James F. Allen and Ferguson, University of Rochester.

• Events are the way by which agents classify certain useful and relevant patterns of change. (must involve at least one object and or involve at least one change of state).

• Actions and Events take time.

• The relationship between actions and events and their effects is complex.

• Actions and Events may interact in a complex ways when are overlaps or occur simultaneously.simultaneously.

• External changes in the world may occur no matter what action agent plans to do, may interact with planned actions.

• Knowledge of the world is necessarily incomplete and unpredictable, thus the predication can only be done on the basis of certain assumptions.
