Abstract: This paper presents the results of applying several graph based interfaces as knowledge acquisition aids in Knowledge-based Systems (KBS) development and discusses various representations: decision trees, conceptual graphs and semantic networks.The viability of a mapping from conceptual graphs to production rules as a means of eliciting knowledge is examined. A comparison is made between a production rule/semantic network representation and conceptual graph/semantic networks. Results indicate that the varying complexities of each representation ensure unbalanced acquisition between schema and heuristic elicitation.To illustrate this, an example in the domain of engineering design for flight simulators is examined. On the basis of our experience we propose a minimal set of criteria for graphics based interfaces which must be satisfied for successful KBS prototyping.
