Vues et points de vue dans un système objet de base de connaissances

Abstract

T. We designed an abject orientee! knowledge based System. Il utilizes case based 5 reasoning (CBR) paradigm suited to studied domains (medical and legal) where analogy reasoning is daily used. This system allows trie doniain expert to design his case model. The expert can reuse classes previously created by himself or an other expert. He can modify these classes to create his own class view relatively the concerned problem, the modifications are performed inside versions. Cases are instantiated and stored to constitute the case base. For a given problem, several indexations exist and, at each indexation corresponds an expert's point of view. When an end user instantiates his case, the system automatically provides him extracted similar cases. The System can generate views of his case to follow the modification impacts on the achieved results.
