Abstract :
For reverse engineering, we need tools that can extract information from documents written before routine digital storage was feasible. Documents contain both text and diagrams; data flow diagrams play a prominent role in software documents. Using current techniques, it is possible to recover the information in a data flow diagram by scanning the printed document and processing the data obtained. Feature extraction and syntax analysis enable the construction of a validated, formalized model of the data flow diagram. Understanding, however, requires a semantic interpretation. We describe a semantic model for data flow diagrams using general techniques that can be applied to other kinds of diagram. We argue that a semantic model is an essential component of a document understanding system; without a semantic model, it is difficult or impossible to extract useful information from a document
