Student modeling services for hybrid web applications

This paper introduces a set of resources that provide web learning environments with student modeling services. SAMUEL is a user modeling server for registering, updating and maintaining student knowledge data from different sources that use their own ontologies. In order to make inferences about student knowledge, it becomes necessary to establish equivalences between concepts of different domains. For this purpose we have developed SONIA, a tool to edit and integrate models which allows semi-automatic ontology mapping. The set of resources is completed with INGRID, an independent generic open learner model for interacting with external student models.
