Component
specs reflect the intrinsic form of HAS - which relates any entity modeled by a topic to its Parts and
Properties. CTM constrains various XTM characteristics to
handle these as CGs requires.
Case Role
specs define the primitive Parts of Situations. These special role types - if well constrained - can
precisely model the role player topics associated by specific verbs and prepositions
Extrinsic associations relate things
not parts or properties of each other.
Often binary, they may offer shortcut links between entities also indirectly related by the intrinsic types
below.
Mereology patterns relate the
Whole of an entity to its
Parts. Trees of such associations can complement the
type hierarchy by decomposing complex objects or substances or situations into simpler parts.
Situation
types use case
roles to model states, events, processes with stages, and
activities. Instances depict complex state changes and can
model the intended meanings for NL phrases and clauses.
Subgraph
associations model nested assertions and have Boolean truth
values. If a Situation becomes one piece of such an object,
its default
truth value arises from validating its semantic constraints.
