The vast majority of multiagent research adressing the problem of the allocation of indivisible goods has concentrated on centralized mechanisms, typically combinatorial auctions. Distributed procedures considers instead that agents locally negotiate by agreeing on deals. In this paper, we consider the restricted negotiation framework consisting of bilateral deals only, and investigate the egal...

Information System (IS) are moving into a service oriented approach. Such approach ensure a need in application adaptibility, taking care of business evolution, services creation or disparition and interaction system allowing dialog with IS. This paper present a global study of system, focusing on dynamic evolution, at business and interaction level. We expose a control architecture allowing su...

This paper presents an adaptation of an existing question answering system for a machine reading task. The proposed method for selecting correct answers relies on textual entailment recognition between hypotheses and texts. The specificities of this method are the generation of hypotheses by parse tree modification and the evaluation of several distance criteria, adapted to take into account te...

In Natural Language Processing and semantic analysis in particular, color information may be important in order to properly process textual information (word sense disambiguation, and indexing). More specifically, knowing which colors are generally associated to terms is a crucial information. In this paper, we explore how crowdsourcing through a game with a purpose (GWAP) can be an adequate st...

Résumé : Dans cet article nous nous interrogeons sur la manière d’outiller la phase de conceptualisation lors de la construction d’une ontologie à partir de textes. La mise en perspective des résultats obtenus à partir de techniques issues de la terminologie et de la fouille de textes est réalisée selon trois plans (discours, linguistique et conceptuel). Cette étude permet de mieux appréhender ...

Résumé Cet article présente les avancées récentes dans le domaine de l’asservissement visuel par imagerie médicale, réalisées notamment depuis les dernières JNRR’07. Le domaine applicatif concerne la robotique médicale où la tâche est réalisée selon un schéma de commande en « boucle fermée » utilisant directement l’information visuelle fournie par une modalité d’imagerie médicale telles l’endos...

This article describes a method to build syntactical dependencies starting from the phrase structure parsing process. The goal is to obtain all the information needed for a detailled semantical analysis. Interaction Grammars are used for parsing; the saturation of polarities which is the core of this formalism can be mapped to dependency relation. Formally, graph patterns are used to express th...

The current development of mobile applications requires more and more to take into account the context of the user, to allow optimizations. In this paper, we propose a contextual information filtering approach for mobile users, involving five context dimensions: spatial, temporal, technical, social and activity. We present the two filtering methods we tested and the results of our preliminary e...

In this paper, we focus on the use of a proprietary resource for a document classification task. The objective is here to measure the impact of the addition of this resource as input for classification features. We show that the use of this resource impacts positively the classification results, for a limited impact on the feature number. Mots-clés : classification de documents, classification ...

We present an overview of linear-time temporal logics with Presburger constraints whose models are sequences of tuples of integers. Such formal specification languages are welldesigned to specify and verify systems that can be modelled with counter systems. The paper recalls the general framework of LTL over concrete domains and presents the main decidability and complexity results related to f...
