  • A composite entity is a thing composed of other things. It is one of the most basic concepts in a knowledge base of commonsense knowledge. It is hard to think of anything that is not a composite entity, and much of our everyday vocabulary is for talking about composite entities.

    Under the concept of “composite entity” we mean to include complex physical objects, such as a door, a cup, a telephone, a chair, and an automobile; complex events, such as a hike, the process of erosion, and a concert; and complex information structures, such as an equation, a sentence, a theory, and a schedule. Some entities, such as books, have both physical and informational components. In this theory of composite entities, we do not make any distinctions among the types of components an entity might have. From the standpoint of the theory of composite entities, the physical-abstract distinction is of no interest.

    A composite entity is characterized by a set of components, a set of properties, and a set of relations.
