This paper describes the development of an image retrieval
system that combines probabilistic and ontological information1. The
process is divided in two different stages: indexing and retrieval. Three

In the last few years, several studies have emphasized the use of ontologies as an alternative to organization of the information.
The notion of ontology has become popular in fields such as intelligent information integration, information retrieval on the Internet,…

Decision tree learning algorithms have been successfully used in knowledge discovery. They use induction in order to provide an appropriate classification of objects in terms of their attributes, inferring decision tree rules. This paper reports on the use of ID3…

Document classification has already been widely studied. In fact, some studies compared feature selection techniques or feature space transformation whereas some others compared the performance of different algorithms. Recently, following the rising interest towards the Support Vector Machine, various studies…

In recent research, it is claimed that deviant features of interlanguage grammars arise only
from the users' knowledge of the rule system of the target language. This paper examines
the relative contribution of the rule system of each of the…

Robotic soccer is a way of putting different developments in intelligent agents into practice, including not only problems such as multi-agent planning and coordination, but also physical problems related to vision and communication subsystems. In this work, we present the…

Le développement accéléré des technologies de communication, de saisie et de traitement de l’information durant les dernières années décennies ouvre la voie à de nouveaux moyens de contrôle social. Selon l’auteur Gary Marx ceux-ci sont de nature non coercitive et…

The assessment is the most complicated task in the teaching work and it should be especially useful to improve the features and results of the learning process proposed at the beginning of an academic year. It must incorporate tools with…
