9.2 Locators: Individual markers (Named referents)

Definition of locators

A locator is a referent which tells us where we can find the individual referred to by the referent, either in the physical world or in a catalog of individuals.

Two kinds of locators

There are two kinds of locators:

  1. Individual markers, and
  2. Indexicals.

This page discusses individual markers, while the next discusses indexicals.

Individual markers are names of persons, places, organizations, etc.

Examples of individual markers

Two examples:

   [Person: John]<-(Expr)<-[Live]->(Loc)->[City: Aalborg]
   "John lives in Aalborg"

Here, "John" and "Aalborg" are locators.
