La correspondance d'objets dans la recherche d'informations : une expérimentation sur un SGBD OO
Abstract : The starting point of our work was to provide a DataBase Management System with a Information Retrieval capability. Accordingly, our goal is to allow the expression of Information Retrieval queries by comparing a query to the documents of the base. We can solve a part of this problem by allowing facilities to describe the matching between the structures of the documents and queries semantics. For now, we split the matching design into two partsÊ: a theoretic one using the logic model of Information Retrieval instanciated with the modal logic, and an operational one based on an algebraic language expressing the elements of the theoretical part. The dichotomy between the theoretical part and the operational one allows the portability of the theoretical concepts, as well as it gives a base for the validation of the matching designed. This work helps an application programmer at a theoretical level to express logical implications between objects as weel as at an operational level by providing a language to define matching between objects. The use of such matching as query predicates will extend the query languages of these systems, by at last takig into account the objects' structures as a whole in queries.
