Depiction and domains in visual knowledge representation

University of British Columbia

Systems need knowledge to behave intelligently in a complex environment. This thesis presents a formalism for characterizing the knowledge in a world while providing a framework that can be utilzed efficiently in computation. Thus Domain Theory is developed as a knowledge representation scheme. Under Domain Theory, the knowledge in a world is divided into domains that are interrelated through the relation of representation. This theory is evaluated as appropriate for knowledge representation using descriptive and procedural adequacy criteria. Domain Theory is applied to produce a working system called Depicts. Depicts is written in Prolog which is well suited for implementing Domain Theory. Given a graphical representation, Depicts returns a relational description and, conversely, given a relational description, Depicts returns a graphical representation.
