Gradual dependencies of the form the more A, the more B offer valuable information that linguistically express relationships between variations of the attributes. Several formalisations and automatic extraction algorithms have been proposed recently. In this paper, we first present an overview of these methods. We then propose an algorithm that combines the principles of several existing approa...

To evaluate the reading performance of children, human assessment is usually involved, where a teacher or tutor has to take time to individually estimate the performance in terms of fluency (speed, accuracy and expression). Automatic estimation of reading ability can be an important alternative or complement to the usual methods, and can improve other applications such as elearning. Techniques ...

The environmental temperature plays an important role in the growing crops. How to make use of computer technology to realize automatic control ambient temperature of greenhouse is a hot issue in the intelligent agriculture. The control of environmental temperature in modern greenhouses is collected and analyzed by monitoring system of greenhouse environment based on Labview software and wirele...

Résumé. L’analyse formelle de concepts (AFC, Ganter et Wille (1999)) est une méthode pertinente d’extraction de connaissances à partir de données complexes d’expression de gènes (Blachon et al. (2007), Motameny et al. (2008)). Dans ce papier, nous proposons d’extraire des groupes de gènes partageant un comportement similaire montrant des changements “significatifs” à travers divers environnemen...

This paper aims at applying a fuzzy arithmetic of intervals calculus and fuzzy quantities to automatic control. This one called φ–calculus fuzzy arithmetic is more practical than the extension principle one and -cut based methods. It comes from a different representation of fuzzy numbers. The present paper follows up work in introducing. The present paper is interested in its use for a fuzzy in...
