Temporal Ontologies

(Related publication: [PUBLink])

Numerous different plan representations exist. There are two main ontologies: sequence-oriented and explicit timeline approaches. The following figure shows these paradigms.

Sequence-oriented approaches work on a branching time-point structure, in which world descriptions (sets of states) are linked by actions. In explicit timeline approaches, actions and states are related to a timeline. The sequence-oriented approaches' branching structure allows reasoning about multiple possible futures in a very direct way, whereas explicit timeline approaches focus on handling complex temporal relations.
