résumé – Note sur la manipulabilité d’une correspondance de choix social Nous étudions la manipulabilité des correspondances de choix social sélectionnant toujours un nombre fixe de candidats. Grâce au théorème de Aswal et al. [2003] qui généralise celui de Gibbard [1973], Satterthwaite [1975], nous montrons (sous la condition d’unanimité) que les seules, parmi ces correspondances de choix, qui...

This work is part of a large research project entitled "Oreillodule" aimed at developing tools for automatic speech recognition, translation, and synthesis for Arabic language. Our attention has mainly been focused on an attempt to present the semantic analyzer developed for the automatic comprehension of the standard spontaneous arabic speech. The findings on the effectiveness of the semantic ...

Based on the well-known Independent Cascade (IC) model, we embed users of the social network in a representation space to extract more robust diffusion probabilities than those defined by classical graphical learning approaches for social influence modeling. Better generalization abilities provided by the use of such a projection space allows our approach to present good performances on various...

This article introduces MLPOST, an OCaml library for scientific drawing. It is based on METAPOST, which allows inclusion of LTEX fragments. OCaml is an appealing alternative to LTEX macro languages, dedicated languages and even to graphic tools. In particular, MLPOST users benefit from OCaml’s expressiveness and static typing. Finally, MLPOST features a declarative style, which differs from the...

CorpusReader is a framework for creating and querying multi-layer corpora, which contain several levels of analysis (morphology, syntax, semantics, etc.) and which are aimed at observing correlations between these levels. Building, representing and querying multi-layer corpora is complex. CorpusReader’s specificity essentially lies in merging the outputs of existing corpus analysis tools, avoid...

Compositionality and Context for Bilingual Lexicon Extraction from Comparable Corpora In this article, we study the possibilities of improving the alignment of equivalent terms monolingually acquired from bilingual comparable corpora. Our overall objective is to identify and to translate highly specialised terminology. We applied a compositional approach enhanced with pre-processed context info...

In this paper, we tackle the problem of the translation of proper names. We introduce our hypothesis according to which proper names can be translated more often than most people seem to think. Then, we describe the construction of a parallel multilingual corpus used to illustrate our point. We eventually evaluate both the advantages and limits of this corpus in our study. Mots clés : noms prop...

The XML language and the object approach both aim at reusing and sharing their content through its improved structure. The XML galaxy is presented beginning with the XML basis (XML, namespaces, DTD and internal encoding), continuing with object-inspired structures (XMI, XML-Schema and Xquery) and modelling tools close to knowledge representation (RDF, RDF-Schema, Topic maps and OWL). Each langu...

The continuous improvement of the quality of machine translation and of speech recognition systems opens new perspectives for the development of spoken translation applications. In this study, based on our own experience with the development of Spoken Translation Systems (STS) for conferences, we analyze and quantify the main difficulties raised by STSs, and discuss possible strategies to migit...

We are developing a system that aims to perform the same inferences as a human reader, on car-crash reports. More precisely, we expect it to determine the causes of the accident as they appear from the text. We describe the general semantic framework in which our study takes place, the linguistic and semantic levels of analysis, and the inference rules used by the system. Mots-clés : sémantique...
