A Method of Understanding Conceptual Diagrams
نویسندگان
چکیده
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 hyp thesis 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.

متن کاملMapping Uninterpreted Schemes into Entity-Relationship Diagrams: Two Applications to Conceptual Schema Design
A method of mapping sets of uninterpreted record or relation schemes into entity-relationship diagrams is described and then applied to two conceptual design problems. First, the method is applied to the design of relational databases. It is shown that the method can be interpreted as a normalization procedure that maps a given relational schema into a new schema that represents an entity-relat...
متن کاملConceptual Understanding of Computer Program Execution: Application to C++
A visual programming language uses pictorial tools such as diagrams to represent its structural units and control stream. It is useful for enhancing understanding, maintenance, verification, testing, and parallelism. This paper proposes a diagrammatic methodology that produces a conceptual representation of instructions for programming source codes. Without loss of generality in the potential f...
