A knowledge acquisition module (KAM) facilitates the encodement of expertise into an expert system. This paper presents a frame based Interactive Graphical Knowledge Acquisition Module (IGKAM). IGKAM provides a knowledge editing environment and graphical representation of the structure of a knowledge base, assisting the knowledge engineer to work through its structure and ensuring the completeness and consistency of the encoded knowledge. The structure of frames used in the module combines the traditional and object oriented approaches to a frame system. The module allows the structure of frames to be redefined, thus enabling it to be interfaced to different expert systems.
