Shood : un modéle méta-circulaire de représentation de connaissances

Abstract : This thesis defines Shood, a knowledge representation model suited for CAD applications. Knowledge Representation Systems and Object Oriented Languages are the inspiration sources of the Shood model. Shood meets three kinds of CAD application requirements: representation power (declarative aspects), integration of computation tools (procedural aspects) and requirement evolution (extensibility). The semantics of its knowledge structuring links (multiple inheritance, disjonction and multiple instantiation) is based on set relationships. Attributs are defined by an extensible set of descriptors. The initial set of descriptors allows the definition of typed attributs, methods for automatic computing attribut values ("inferences") and procedural constraints on attribut values ("constraints"). Shood methods allow the definition of generic functions. Input arguments are used by a classification mecanism to find the best suited method to execute. Methods can be reused in a declarative or procedural style. Extensibility is achieved by the reflexive definition of the model: Shood concepts are defined in terms of Shood concepts themselves using meta-classes.
