Example 2 | Q_eaten_in_eatingselectional preferencefood (Q2095) |
Example 3 | Q_hearer_in_communicationselectional preferenceorganism (Q7239) |
Planned use | add to (possibly newly created) items describing event participants |
Expected completeness | always incomplete (Q21873886) |

Motivation
[edit]See our property proposal “event role” and project Events and Role Frames.
Several selectional preference statements imply an OR.
This is one of the five proposed properties that should be considered together: "event role", role in event, "selectional preference", "event argument", and "argument type".

Discussion
[edit]- Oppose. This relationship is already perfectly covered by union of (P2737). E.g., eater (Q20984678)union of (P2737)list of values as qualifiers (Q23766486)
list item (P11260)organism (Q7239). Furthermore, the proposed label and description do not do a good job of conveying the use case. "Selectional preference" makes no sense, and "a combination of P31 and P279" is not sufficiently precise: items that are allowed to fill a role (i.e. be values of Wikidata:Property_proposal/event_arguments_and_types#event_argument) must be instances of the given class or its subclasses; in sparql parlance, P31/P279*. That's exactly one P31 followed by any number of P279s. Not just any chain of P31s and P279s. Swpb (talk) 21:17, 4 December 2023 (UTC)
- Reply You are raising several issues that need to be addressed. The term " Selectional Preferences" is commonly used in linguistics to indicate the preferred semantic content of a predicate argument. For example, we might specify that eater (Q20984678) is preferably an organism (Q7239) or that assassin (Q55983771) is preferably a human (Q5). These are preferences, not constraints as they can be and sometimes are violated, e.g., "my boat eats money". We also leave the utilization of these preferences up to to applications. For example, an application might interpret a violation of the selectional preferences as an indicator of a metaphor. The phrase "a combination of P31 and P279" was meant as an example which should probably be removed. It is also important to note that selectional preferences are specified for a class item, e.g., eater (Q20984678), but they apply to the instances that play the role of the "eater" in the instances of eating (Q213449) such as Pilgrim's table at Saint Julian’s hospital (Q122030564). --Anatole Gershman (talk) 23:50, 7 December 2023 (UTC)
