The Degradation of Knowledge Base Integrity

John Debenham, University of Technology, Australia

In a unified knowledge representation data, information and knowledge are all represented in a single formalism as items. Objects are item building operators. Items and objects contain two types of acceptability measures that measure the invalidity of item instances. A quantitative calculus estimates the extent to which knowledge base integrity may be expected to degrade as time passes. This calculus is simplified by the use of the unified knowledge representation. Expressions in this calculus are simplified if the knowledge has been decomposed.
