Les travaux presents dans cette thèse concernent les raisonnements non-monotones dans les langages orientes objets, utilisant les valeurs par défaut et l'héritage multiple. Nous cherchons à répondre à la question: pour un individu particulier I et une propriété P, quelles sont les valeurs qui décrivent P?. Le mécanisme d'héritage est mis en oeuvre sur la base de connaissance lors de cette question. Il rencontre les problèmes de conflit entre deux valeurs contradictoires héritées. Les mécanismes d'héritage existants n'ont pas de solution objective à ce problème. Nous proposons un prototype de langages à objets qui offre certains outils pour résoudre les conflits. Nous avons crée deux solutions syntaxiques qui réduisent le nombre de situations de conflit. Pour les conflits non résolus par ces deux outils, nous présentons une notion de point de vue sans contraintes sémantiques et syntaxiques pour les créateurs de la base. Cette notion de point de vue permet aux utilisateurs de choisir librement les valeurs interessantes parmi celles possibles héritées. Des informations, déduites par héritage, les aident à faire un choix. Cette information est composée de points de vue. Enfin, nous présentons une formalisation logique, en logique des défauts, du mécanisme d'héritage avec points de vue

Reasoning under uncertainty is always based on a specified language or for malism, including its particular syntax and semantics, but also on its associated inference mechanism. In the present volume of the handbook the last aspect, the algorithmic aspects of uncertainty calculi are presented. Theory has suffi ciently advanced to unfold some generally applicable fundamental structures and methods. On the other hand, particular features of specific formalisms and ap proaches to uncertainty of course still influence strongly the computational meth ods to be used. Both general as well as specific methods are included in this volume. Broadly speaking, symbolic or logical approaches to uncertainty and nu merical approaches are often distinguished. Although this distinction is somewhat misleading, it is used as a means to structure the present volume. This is even to some degree reflected in the two first chapters, which treat fundamental, general methods of computation in systems designed to represent uncertainty. It has been noted early by Shenoy and Shafer, that computations in different domains have an underlying common structure. Essentially pieces of knowledge or information are to be combined together and then focused on some particular question or domain. This can be captured in an algebraic structure called valuation algebra which is described in the first chapter. Here the basic operations of combination and focus ing (marginalization) of knowledge and information is modeled abstractly subject to simple axioms.

L'OBJET DE CETTE THESE EST L'ETUDE DU RAISONNEMENT NON MONOTONE ET DE SON TRAITEMENT ALGORITHMIQUE DANS UN SYSTEME A HERITAGE MULTIPLE Y3. LE GRAPHE D'HERITAGE EST UN GRAPHE ORIENTE SANS CIRCUIT ET SANS ARC DE TRANSITIVITE. LA RELATION ENTRE CLASSES (OU CONCEPTS) EST UN LIEN DE GENERALISATION/SPECIALISATION. CHAQUE CLASSE EST DEFINIE PAR LA LISTE DE CES PROPRIETES. EN REPRESENTATION DE CONNAISSANCES, IL EST TRES NATUREL D'EMPECHER L'HERITAGE DE CERTAINES PROPRIETES A L'AIDE DE LIENS SEMANTIQUES APPELES EXCEPTIONS. CES DERNIERS VISENT A REPRESENTER L'ATYPICALITE ET DONC A REALISER DES RAISONNEMENTS NON MONOTONES. TROIS TYPES D'EXCEPTIONS SUR LES PROPRIETES SONT DEFINIS ET COMPARES. LA SEMANTIQUE OPERATIONNELLE DE CELLES-CI S'INTEGRE A CELLE DE L'HERITAGE MULTIPLE DEFINIE DANS Y3. CETTE DERNIERE EST BASEE SUR LES NOTIONS FONDAMENTALES DE L'HERITAGE MULTIPLE: L'ENSEMBLE DE VISIBILITE, LE MASQUAGE ET L'ENSEMBLE DE CONFLIT. UN ALGORITHME DE COMPLEXITE LINEAIRE EST DONNE POUR CHAQUE EXCEPTION. PUIS, NOUS PROPOSONS UNE THEORIE QUI FUSIONNE CES DIVERSES EXCEPTIONS. L'ALGORITHME DE TRAITEMENT DES DIVERSES EXCEPTIONS CONSERVE UNE COMPLEXITE DE CALCUL LINEAIRE. LE RAISONNEMENT NON MONOTONE INDUIT PAR LE MASQUAGE ET LES EXCEPTIONS EST FORMALISE EN LOGIQUE DES DEFAUTS. LES MODELES LOGIQUES PROPOSES SONT TRES PROCHES DE LA SEMANTIQUE OPERATIONNELLE DU SYSTEME A HERITAGE MULTIPLE AVEC EXCEPTIONS

PARMI LES METHODES DE RAISONNEMENT NON MONOTONE, LA CIRCONSCRIPTION DE MC CARTHY EST UNE DES PLUS PROMETTEUSES. ELLE REPOSE SUR UN SCHEMA FACILE A EXPRIMER ET BENEFICIE D'UNE SEMANTIQUE SIMPLE ET NATURELLE. LES LIENS ETROITS ENTRE LA COMPLETION ET LA CIRCONSCRIPTION SONT EXPLICITES. LES PRINCIPAUX RESULTATS CONCERNANT LA CIRCONSCRIPTION, SONT RASSEMBLES ET UNE PRESENTATION PLUS UNIFIEE EST PROPOSEE. DIVERSES AIDES AU CALCUL EFFECTIF DE LA CIRCONSCRIPTION SONT DONNEES PARMI LESQUELLES UN THEOR"ME PERMETTANT D'ECARTER PROVISOIREMENT UNE PARTIE DES DONNEES ET UNE UTILISATION DE LA CIRCONSCRIPTION POINT PAR POINT. LES RELATIONS ENTRE MODELES SOUS JACENTES A L'IDEE DE CIRCONSCRIPTION SONT PRECISEES
