Interdisciplinarité et recherche participative : deux régimes de recherche pour la transition écologique et solidaire. Une mise en perspective programmatique

Séro-agglutination rapide et macroscopique pour la recherche d'anticorps de la Fièvre Q. chez les animaux

Une perspective analytique pour la recherche d'information. Application : conception et évaluation de Tissue Microarrays

Beyond classical techniques to explore a document collection such as Information Retrieval and graphical visualisation we present in this paper an analytic view which combines the expression of a goal-centered query and the construction of a virtual multimedia document. Building this synthetic document is considered as a complex adaptation problem. We propose a first approach to characterise th...

Structure et proximité pour la recherche documentaire

Our study compares the effectiveness of an information retrieval system based on the proximity of the query term occurrences in the documents and an IRS based on a language model with Dirichlet smoothing and with the Okapi BM25 model. Our proximity based model computes at each position in the document a value much higher as some occurrences of all the query terms are close to this position. Mor...

Apprentissage Actif avec une Méthode de Réordonnancement pour l'Indexation et la Recherche de Vidéos

Video retrieval can be done by ranking the samples according to their probability scores that were produced by classifiers. It is often possible to improve the retrieval performance by re-ranking the samples. In this paper, we proposed such a method and we combined this method with active learning for video indexing. Experimental results showed that the proposed re-ranking method was able to im...
