Graphical and Formal Knowledge Specification with KARL

Published: 1994
Nummer: 284
Institution: University of Karlsruhe, Institute AIFB
Erscheinungsort / Ort: 76128 Karlsruhe, Germany


The paper discusses an approach which allows the specification of a knowledge-based system (kbs) at several levels. The Knowledge Acquisition and Representation Language KARL combines a description of a kbs at the conceptual level supported by graphical modelling primitives with a description at a formal and executable level. Therefore, a KARL-specification can be used as a means for communication between expert and knowledge engineer as well as an intermediate representation, closing the conceptual gap between an informal specification and an implementation of a kbs. In the paper, KARL is mainly discussed as a graphical modelling language.
