andIndividual

andIndividual is a term used in discussions of knowledge representation and linguistics to denote the conjunction of two or more individuals into a single referential unit. It is typically treated as a binary operation that takes two individual references and yields a composite referent intended to capture the joint reference presented by a coordinated phrase.

In linguistic semantics, andIndividual helps model coordinated noun phrases such as "Alice and Bob" by signaling that the phrase refers to the joint entity constituted by the two persons rather than to either one alone. In some formal theories the operation yields a higher-order object or a tagged set that preserves the identities of the components while enabling joint properties to be attributed to the coordination as a whole.

In knowledge representation and artificial intelligence, andIndividual may be implemented as a wrapper or relation that links two individuals under a coordination label. It is distinct from simply creating a set or list, because it encodes the coordination semantics needed for tasks such as pronoun resolution or scope determination in natural language understanding pipelines. Usage varies across frameworks, and there is no universal standard.

Origins of the term are informal; it has appeared in academic discussions and pedagogical materials exploring the semantics of coordination and composite referents. It is most often referenced in theoretical contexts rather than as a standard feature of mainstream ontologies.
