A multimedia knowledge-based system

The multimedia knowledge-based system (MMKS) is a knowledge-based system which provides a uniform environment for flexible human-machine communication using multiple media. MMKS has a knowledge representation method called predicate logic based on objects (PLOB) and an object-base defined based on a relational data model. PLOB is a first-order predicate logic in which every individual is regarded as an object, e.g. an integer, a string, and an image. The object-base is a collection of relations, and a relation is a set of tuples of objects. The management function of the object-base is defined based on SQL. The authors present the definition of MMKS and MMKS systems implemented on workstations.<
