Résumé. Nous utilisons un algorithme d'amorce mutuelle (Riloff et Jones 99), entre des couples de termes d'une relation et des patrons de phrase. À partir de couples d'amorce, le système génère des listes de patrons qui sont ensuite enrichies de façon semi-supervisée, puis utilisées pour trouver de nouveaux couples. Ces couples sont à leur tour réutilisés pour générer, par itérations successive...

this article addresses the phonetic and phonological representation of h- phrase accent in the tonal structure of persian pre-nuclear accents. in an experimental study, three groups of pre-nuclear accentual phrases, namely, phrases with antepenultimate, penultimate and final stress pattern, were selected for tonal examination. materials were designed so as to yield under-pressure and pressure f...

In recent digital library systems or World Wide Web environment, parallel corpora are used by many applications (Natural Language Processing, machine translation, terminology extraction, etc.). This paper presents a new cross-language information retrieval model based on the language modeling. The model avoids query and/or document translation or the use of external resources. It proposes a str...

This paper presents a mathematical de nition of Left-Associative Grammar, and describes its formal properties. Conceptually, LA-grammar is based on the notion of possible continuations, in contrast to more traditional systems such as Phrase Structure Grammar and Categorial Grammar, which are linguistically motivated in terms of possible substitutions. It is shown that LA-grammar generates all a...

In this manuscript we present the mathematical aggregation operators and their application to the video querying. This work is divided in three parts. The first one offers the definition of mathematical aggregation operators and some properties, followed by an extensive overview of the existing operators. The second part is dedicated to the study of the aggregation under uncertainty. We present...
