General description
| Name: | Situation |
|---|---|
| Submitted by: | AldoGangemi |
| Also Known As: | situation |
| Intent: | To represent contexts or situations, and the things that are contextualized. |
| Domains: | |
| Competency Questions: |
|
| Solution description: | - |
| Reusable OWL Building Block: | http://www.ontologydesignpatterns.org/cp/owl/situation.owl (1336) |
| Consequences: | We can contextualize things that have something in common, or are associated: a same place, time, view, causal link, systemic dependence, etc.
We can also reify n-ary relations as situations. |
| Scenarios: | The lecture was held in January 1921 by Bela Fleck, with some physicians in the audience making questions, in a very relaxed athmosphere. |

Elements
The Situation Content OP locally defines the following ontology elements:
hasSetting (owl:ObjectProperty) A relation between entities and situations, e.g. 'this morning I've prepared my coffee with a new fantastic Arabica' (i.e.: (an amount of) a new fantastic Arabica hasSetting the preparation of my coffee this morning).
hasSetting page
Situation (owl:Class) A view on a set of entities. It can be seen as a 'relational context', reifying a relation.
For example, a PlanExecution is a context including some actions executed by agents according to certain parameters and expected tasks to be achieved from a Plan; a DiagnosedSituation is a context of observed entities that is interpreted on the basis of a Diagnosis, etc.
Situation is also able to represent reified n-ary relations, where isSettingFor is the top-level relation for all binary projections of the n-ary relation. If used in a transformation pattern for n-ary relations, the designer should take care of:
- creating only one situation for each instance of an n-ary relation, otherwise the 'identification constraint' (Calvanese et al., IJCAI 2001) could be violated
- adding an 'exact cardinality' restriction corresponding to the arity of the n-ary relation, otherwise the designer would actually represent a polymorphic relation.

| Modeling issue | Competency question | Domains |
|---|---|---|
| Situation classification | What situations satisfy a certain description? What descriptions can be (partly) satisfied by that situation? What situations (partly) satisfying a certain description can emerge out of this dataset? |
