Imprecise diagrams occur in many situations. We propose a five-stage architecture for interpreting such diagrams, and have implemented this approach in an automatic grading tool for answers to examination questions. The approach is based on identifying (possibly malformed) minimal meaningful units and interpreting them to yield a meaningful result. Early indications are that the tool's performance is similar to human markers.
