Predicates And Semantic Roles

The type named in the heading of a relation would typically have to be defined partly in terms of a Semantic Role.  In the Relation INVITES, for example, the person inviting belongs to the set INVITERS, which is a subset of AGENTS, i.e., the set of entities capable of acting volitionally.  AGENTS is in turn is a subset of ACTORS.  An entity belongs to ACTORS when, although not necessarily capable of volition, it “… in some intuitive way performs, effects, or controls the situation.”  (I’ve lost track of the source.)  In turn, the person invited belongs to the set INVITEES, which is a subset of PATIENTS, entities acted upon.

Agents, Actors, and Patients are all, of course, Semantic Roles.

About Cliff Wirt

I am a banking DBA with various and sundry interests, including art, poetry, philosophy, music, languages, relational algebra, database administration, and blueberries. Don't forget the blueberries. Some of these interests tie in in surprising though usually tangential ways with database theory. Even the blueberries. I have published one article in a Philosophy Journal, and I have one painting in a corporate collection (housed in what used to be the Amoco building in Chicago). According to 12andMe, my paternal haplogroup is I2, my maternal H5. The Neanderthal percentage of my ancestry is 3%. My most famous ancestor is William Wirt (from whom I get my last name, though possibly not my Y chromosome), who defended the rights of the Cherokees before the Supreme Court, and ran for President in 1832, carrying one state.
