The Semantics of Data Flow Diagrams
 In Proceedings of the International Conference on Management of Data
, 1993
"... In this article we provide insight as to how semantics can be attached to Data Flow diagrams. We first present a method for transforming a Data Flow Diagram(DFD) to a PetriNet (PTnet) which specifies the synchronization aspects of a DFD. Secondly, we sketch how a Data Flow diagram may be transf ..."

Timed Data Flow Diagrams
, 1996
"... Data Flow Diagrams (DFD's) are widely used in industry to express requirements specifications. However, as used in practice, there has been no precise semantics for DFD's, let alone an incorporation of a model of time. In this paper, we augment the Formalized Data Flow Diagrams (FDFD' ..."

The control group of 10 students studied 39 schematic diagrams of aircraft systems. The treatment group of eight students studied the same schematic diagrams plus conceptual diag ..."

Weighted flow diagrams for statistical output
"... Many official statistics are flow data, e.g. population dynamics, System of National Accounts (SNA) and energy statistics. Figures of these statistics are usually presented on the internet using detailed tables that are hard to digest. An alternative but intuitive visualization for these data are we ..."

are weighted directed flow diagrams. These diagrams show the flow of quantities through a system. For small and nicely distributed data flow diagrams are an attractive means of visualisation. Data of NSI's however often is skewed and detailed which leads to a cluttered flow diagram where important details
Flow Diagrams, Turing Machines and Languages with only Two Formation Rules
 Communications of the ACM
, 1966
"... In the first part of the paper, flow diagrams are introduced to represent inter ah mappings of a set into itself. Although not every diagram is decomposable into a finite numbm of given base diagrams, this becomes hue at a semantical level due to a suitable extension of the given set and of the basi ..."

Generating Summaries of Work Flow Diagrams

"... FLOWDOC is a prototype text generator that summarizes information from work flow graphs in a business reengineering context. A richer ontology than is typically used allows generalization of input data during content selection, and combination of data during sentence planning. Keywords: Summarizati ..."

Its input comes from SHOWBIZ (Wittenburg 96) , a GUI used in this environment to represent as work flow diagrams both the Present Mode of Operation (PMO) of a working group and the Future Modes of Operation (FMOs) suggested by reengineering consultants.
