A Syntactic-Semantic Approach for Pattern Recognition and Knowledge Representation

The attributed grammar is expanded by emphasizing semantic information.Various relations between variables of a production,and control strategies are introduced.As a result, two kinds of generalized attributed grammars are obtained.On the basis of such attributed grammars,a syntactic-semantic approach is suggested for one dimensional wave description, pictorial pattern recognition,hierarchical image processing and knowledge representation in some specific domains.
