Orphan Works 3: The Role of Private & Public Registries
One question regarding orphan works is the role public and private registries might play in any orphan works solution. The most obvious of these registries, the Copyright Office's own registration and recordation system, provides a wealth of copyright information but has limitations based on both technological requirements and the fact that registration and recordation is not mandatory in the United States. There are other registries that have ownership information, and there has been some sugge

A Bayesian Student Model without Hidden Nodes and Its Comparison with Item Response Theory
The Bayesian framework offers a number of techniques for inferring an individual's knowledge state from evidence of mastery of concepts or skills. A typical application where such a technique can be useful is Computer Adaptive Testing (CAT). A Bayesian modeling scheme, POKS, is proposed and compared to the traditional Item Response Theory (IRT), which has been the prevalent CAT approach for the last three decades. POKS is based on the theory of knowledge spaces and constructs item-to-item gra

Une analyse automatique de cartes conceptuelles pour modéliser l'apprenant
Les hypermédias adaptatifs dédiés à l'enseignement souffrent généralement d'une modélisation soit trop rigide, les destinant à l'apprentissage d'un champ disciplinaire déterminé a priori, soit trop grossier, ne permettant pas la construction d'un modèle suffisamment riche pour adapter finement le document produit. Notre objectif est d'aller à l'encontre de ces problèmes, en proposant une modélisation de l'apprenant plus riche car non basée sur une modélisation par recouvrement. L
