A new synthetical knowledge representation model that integrates the attribute grammar model with the semantic network model was presented. The model mainly uses symbols of attribute grammar to establish a set of syntax and semantic rules suitable for a semantic network. Based on the model, the paper introduces a formal method defining data flow diagrams (DFD) and also simply explains how to use the method.
