Plateforme objet d'évaluation orientée point de vue d'un système d'information

In this paper, we propose an object-oriented framework for annotating viewpoint-based Knowledge Discovery from Databases (KDD) processes mainly based on the use of the design patterns. It ensures a development-evaluation-evolution process of an information system based on the Web according to multiple viewpoints. We show the benefits of using design patterns in such modelling. We define a viewpoint as a perception of on expert on a KDD process, perception referred by its own knowledge. In order to facilitate both the reusability and the adaptability of a KDD process, and to reduce its complexity with maintaining the trace of the past analysis viewpoints, the KDD process will be considered as a view generation and transformation, where views are annotated by metadata to store the discovered knowledge.
