A conceptual diagram is a line drawing which represents semantic structure of concepts usirtg simple yeometric entities. This paper presents a method of understanding conceptual diagrams. The objective of our method is to interpret semantic roles of geometric entities in conceptual diagrams. In conceptual diagrams, however, a single geometric entity plays various semantic roles for representing concepts, becanse there are no strict rules for writing conceptual diagmms. To cope with this problem, we introduce the strategy of hypthesis generation and verificution; hypothesized interpretations are verified by relaxation which takes account of the semantic relation to other entities. &om the experimental results using 50 conceptual diagrams, we discuss the effectiveness and the limitations of our method. 1
