La problématique traitée dans la thèse s’inscrit dans le cadre de l’analyse d’usage dans les systèmes de recherche d’information. En effet, nous nous intéressons à l’utilisateur à travers l’historique de ses requêtes, utilisées comme support d’analyse pour l’extraction d'un profil d’usage. L’objectif est de caractériser l’utilisateur et les sources de données qui interagissent dans un réseau afin de permettre des comparaisons utilisateur-utilisateur, source-source et source-utilisateur.

Abstract:

<p>Today there exist several systems that lack usability. The reasons are, among others, the pressure to add more features in the system, but also that focus has been earlier on technology and functionality. It becomes more important to think of the user, so that systems can be more usable. By focusing on the user, the user experience can enhance, which results in more satisfied users.</p><p>User involvement in the system development process is one way to learn and receive information about the user.

Abstract:

Recommender systems assist users in finding what they want. The challenging issue is how to efficiently acquire user preferences or user information needs for building personalized recommender systems. This research explores the acquisition of user preferences using data taxonomy information to enhance personalized recommendations for alleviating cold-start problem. A concept hierarchy model is proposed, which provides a two-dimensional hierarchy for acquiring user preferences. The language model is also extended for the proposed hierarchy in order to generate an effective recommender algorith

Mobile television ( TV ) is a relatively new and unknown field of communication. Thus, role players in this field of communication find themselves in a new context for relationship. This raises the question as to what the key challenges in the relationship between content providers and users in mobile TV involve. More specifically, the following questions should be answered. Does mobile TV display particular characteristics of new media? If so, then how could content providers meet the challenge of understanding the user profile in mobile TV as a new medium? Also, how could content providers

Finally, we use depth-first search and breath-first search strategies to explore the graph.Using the semantic information an

Abstract:

L'augmentation constante du volume d'information disponible sur le Web a rendu compliquée la découverte de nouvelles sources d'intérêt sur un sujet donné. Les experts du renseignement doivent faire face à cette problématique lorsqu'ils recherchent des pages sur des sujets spécifiques et sensibles. Ces pages non populaires sont souvent mal indexées ou non indexées par les moteurs de recherche à cause de leur contenu délicat, les rendant difficile à trouver. Nos travaux, qui s'inscrivent dans ce contenu du Renseignement d'Origine Source Ouverte (ROSO), visent à aider l'expert du renseignement da

Abstract:

Les Interfaces Cerveau-Ordinateur basées sur l’Imagerie Mentale (IM-ICO) permettent auxutilisateurs d’interagir uniquement via leur activité cérébrale, grâce à la réalisation de tâchesd’imagerie mentale. Cette thèse se veut contribuer à l’amélioration des IM-ICO dans le but deles rendre plus utilisables. Les IM-ICO sont extrêmement prometteuses dans de nombreuxdomaines allant de la rééducation post-AVC aux jeux-vidéo. Malheureusement, leurdéveloppement est freiné par le fait que 15 à 30% des utilisateurs seraient incapables de lescontrôler. Nombre de travaux se sont focalisés sur l’amélioratio

Abstract:

There is a fast increase of information and data generation in virtual environments due to microblogging sites such as Twitter, a social network that produces an average of 8, 000 tweets per second, and up to 550 million tweets per day. That's why this and many other social networks are overloaded with content, making it difficult for users to identify information topics because of the large number of tweets related to different issues. Due to the uncertainty that harms users who created the content, this study proposes a method for inferring the most representative topics that occurred in a t

Abstract:

A acomodação da diversidade de perfil de usuários no projeto de interface de sistemas é um problema freqüente nas atividades do projetista da interação homem-computador. Conseqüentemente, o usuário encontra barreiras ao utilizar interfaces que não foram produzidas para o seu perfil. Este trabalho apresenta uma solução, destinada aos projetistas de famílias de sistemas interativos, para a acomodação e expressão da diversidade por meio da criação e uso de padrões de interface em camadas de personas - as PICAPs. Neste conceito, os padrões de interface apóiam o projetista no direcionamento de solu

Abstract:

De nos jours, les Réseaux Sociaux sont omniprésents dans tous les aspects de la vie. Une fonctionnalité fondamentale de ces réseaux est la connexion entre les utilisateurs. Ces derniers sont engagés progressivement à contribuer en ajoutant leurs propres contenus. Donc, les Réseaux Sociaux intègrent également les créations des utilisateurs ; ce qui incite à revisiter les méthodes de leur analyse. Ce domaine a conduit désormais à de nombreux travaux de recherche ces dernières années. L’un des problèmes principaux est la détection des communautés. Les travaux de recherche présentés dans ce mémoir

Abstract:

L’utilisation de préférences suscite un intérêt croissant pour personnaliser des réponses aux requêtes et effectuer des recommandations ciblées. Pourtant, la construction manuelle de profils de préférences reste à la fois complexe et consommatrice de temps. Dans ce contexte, nous présentons dans cette thèse une nouvelle méthode automatique d’extraction de préférences basée sur des techniques de fouille de données. L’approche que nous proposons est constituée de deux phases : (1) une phase d’extraction de toutes les règles de préférences contextuelles intéressantes et (2) une phase de construct

Abstract:

Le vieillissement observé dans la population est souvent responsable de déficits amenant une perte d’autonomie, et une situation de handicap plus ou moins importante. Ces difficultés n’ont pas toujours de possibilités thérapeutiques (i.e. médicamenteuses ou chirurgicales). En revanche, il faut pouvoir soigner, diminuer ou neutraliser ces symptômes. Les technologies numériques semblent pouvoir jouer un rôle sur certaines manifestations du vieillissement en aidant, en assistant, en stimulant, en rééduquant, et, in fine, fournir davantage de qualité de vie et d’autonomie.Cependant, cette nouvelle
