Abstract

Overlap between knowledge acquisition (KA) techniques means that parts of a knowledge base (KB) acquired using one technique may be refined and extended using some other technique. There is a need for knowledge interchange. Develops a knowledge reformulation technique and tool to support the knowledge engineer in performing knowledge interchange. The approach has 2 main types of functionality. If contains functions used for translation from and into knowledge acquisition KBs, using the Knowledge Interchange Format (KIF) aas an intermediate language. The translation functions are based on grammars of KA techniques as well as approaches to formalize the knowledge acquisition KBs. Develops translators for the well known KA techniques card sort and repertory grid. The translators are written using the definite clause grammar (CDG) formalism, which is based on Prolog. The 2nd type of functions in the knowledge reformulation approach are denoted adaption functions. The dapation functions are used for KB organizing, structuring and editing. These functions are utilized by the knowledge engineer to modify KBs before and after translation. Presents the knowledge reformulation technique and tool, along with the methodological basis for the approach. An example of how the Knowledge Reformulation tool (KRF) can be used is also included
