On the Effective Interaction and Knowledge Sharing of Users Analyses in a Decisional Process

This paper aims to establish coordination and knowledge sharing between the users of a decisional process based on Common Warehouse Metamodel. We present a set of relations to model and formalize interaction and interdependence between various analyses according to users viewpoints. Those relations aim to enhance metadata reuse, ensure coordination and mutual understanding between different users of a decisional process. Then, to implement our proposal we initiate the Common Case Reuse Framework based on the defined relations, on the viewpoints annotations, and on Case-Based Reasoning process. The Framework will improve reusability of users analysis and experiences, and guide novice users during the exploitation of a decisional process in terms of viewpoint.
