Quelle méthode ergonomique élaborer pour évaluer les moteurs de recherche exploratoire?
Exploratory search systems (ESSs) are search engines that help users to explore a topic of interest. A shortcoming of current evaluation methods is that they cannot be used to determine if an ESS can help the user in performing exploratory search tasks. To address this issue, we introduce our approach for designing a user-centered evaluation method for ESSs. Our method takes into account users’...
متن کاملEnsembles d ’ unicité pour les polynômes ∗
Let E ⊂ C be a compact set of positive logarithmic capacity. Let us suppose that for every polynomial P = id we have P −1 (E) = E. Then for all no constant polynomials f and g such that f −1 (E) = g −1 (E) we have f = g.
متن کاملPilotage des processus collaboratifs dans les systèmes PLM. Quels indicateurs pour quelle évaluation des performances ?
Companies that collaborate within the product development processes need to implement an effective management of their collaborative activities. Despite the implementation of a PLM system, the collaborative activities are not efficient as it might be expected. This paper presents an analysis of the problems related to the collaborative work using a PLM system, identified through a survey. From ...
متن کاملUn critère dévaluation pour les K-moyennes prédictives
Résumé. L’algorithme des K-moyennes prédictives est un des algorithmes de clustering prédictif visant à décrire et à prédire d’une manière simultanée. Contrairement à la classification supervisée et au clustering traditionnel, la performance de ce type d’algorithme est étroitement liée à sa capacité à réaliser un bon compromis entre la description et la prédiction. Or, à notre connaissance, il ...
متن کاملToposes pour les nuls
The \generalized universe of sets" aspect of toposes is relatively easy to understand and is well documented in the literature: start with Goldblatt [1] and proceed via Mac Lane and Moerdijk [5], or MacLarty [4], to Johnstone [2]. The basic trick is to use categorical properties to characterize set-theoretic constructions in the category of sets, and thence to transfer them to other categories ...
