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.展开更多

The main emphasis is how to represent a multi-thread dialogue model in direct manipulation user interfaces. It is shown that control sequence within dialogues, communication with other dialogues,and some computations for applications can be specified with a syntactic and semantic notation. The attribute grammar specification can be implemented using an attribute grammar interpreter embedded in the runtime structure supporting communication, synchronization, and dialogue execution.展开更多

The parallelism is achieved by constructing the so-called parallel visit sequences and accordingly augmenting the ordinary evaluation driver as well.

It integrates a hybrid editor,an incremental semantic analyzer,a multi-entry parser,an incremental unpaser and a source-level debugger into a single tool.The integration is realized by sharing common knowledge,among all the components of the system and by task-oriented comhination of the components.Nonlocal attribute grammar is adopted for specifying the common knowledge about the syntax and semantics of C language.The incremental attri bute evaluation is used to implement the semantic analyzer and the unparser to increase system efficiency.CCD keeps the preprocessors and comments most regular to make it practical.展开更多
