Exploitation de la morphologie pour l'extraction automatique de paraphrases grand public des termes médicaux

The medical area conveys very specific terms (p. ex., blepharospasm, appendicectomy), which are difficult to understand by people without medical training. We propose an automatic method for the acquisition of paraphrases, which we expect to be easier to understand than the original terms. The method is based on the morphological analysis of terms, syntactic analysis of texts, and text mining o...

Etudier la sémantique des termes techniques : des théories à la pratique

Résumé : L’objectif de cet article est de montrer comment on peut étudier la sémantique des termes techniques et comment on peut passer des théories sémantiques de la terminologie à la pratique, c’est-à-dire à l’analyse de corpus. Nous procédons à une analyse sémantique de plusieurs milliers de mots spécifiques d’un corpus de textes techniques. A cet effet, nous adoptons une méthodologie qui re...

Estimation automatique de la distribution des sens de termes

In order to promote the usage of the natural language in information systems, it seems interesting to obtain lexical data allowing a satisfactory lexical disambiguation. The distribution of word senses is one such important type of data, but still is uneasy to obtain. We are currently developing a system for analysing thematics aspects of texts and undertaking word sense disambiguation based on...

À la recherche des paramètres des modèles de RI

We address in this study the problem of estimating standard IR model parameters on new collections for which no relevance judgements are available. To do so, we rely on past collections with relevance judgements and introduce a new, collection independent query representation. From this representation as well as from past collections, we learn a regression function linking queries to parameter ...
