Abstract
Arrows illustrate a large variety of semantics in diagrams. An automated interpretation of arrow diagrams would be extremely useful in pen-based interface. Through the formalization of the structural patterns of arrow diagrams, this paper identifies three structural properties of arrow diagrams that contribute the interpretation of arrows: (1) the assignment of the components to the three slots, (2) the semantic types of these components, and (3) the orientation of the objects.
