Modélisation et recherche basées sur le contenu d'objets complexes : le système EMIR

Abstract : This thesis introduces the Extended Model for Information Retrieval (EMIR) whose objective is the modelling of complex objects with strong individual features. Conceptual modelling of databases is a heavy task. Abstracting object structures into classes is not always easy. In some cases (e.g. Information Retrieval from document bases), it is rather unfeasible because of the individual characteristics of each object (document). EMIR aims to relax the conceptual schema constraint by allowing objects to have individual features to be added to those abstracted in some related conceptual entities. EMIR objects have a tri-partite structure : attributes, comonent objects and links between components. The conceptual schema is made of object categories (also described in the same tri-partite fashion) and semantic relationships. The link between an object and a category is baptized realization link. The object implements a structure inspired by the category and is allowed to have individual added features.
