Sur Quelques Limitations des Algorithmes Dans Le Traitement des Suites

— A relation (I.F.) is given which partially expresses the conditions to be satisfied by a séquence transformation in order to be "calculable". We can apply this relation on gênerai space and without using recursive notions. This relation gives us sharp négative results concerning séquence transformations. This is shownfor decidability problems of periodicity,for extraction problems of converge...

However, the IRS shows certain differences between user relevance and system relevance. These gaps are essentially related to the imperfection of the indexing process (as approach related to the IR), to problems related to the misunderstanding of the natural languag...

Composition Dynamique d'Informations dans le Cadre de la Communication Homme Machine - La problématique de la Pertinence dans la CHM

Users of information systems, when engaged in search, selection and reading activities, are often overloaded with huge amounts of information. This situation is even worse when information arrives in continuous streams, such as in industrial supervision systems. In order to help the users in such situations, the approach suggested here is a system that can take the initiative to adapt presentat...
