OWL-OLM : interactive ontology-based elicitation of user models

User-adaptive systems for the SemanticWeb need approaches for user modeling that work, unlike traditional approaches, under the open-world assumption. A novel framework for eliciting a user’s conceptualization based on an ontology-driven dialog is presented here. It has been integrated in an RDF/OWL-based adaptive semantic-web software architecture for learning content management. We illustrate the implemented framework with an application scenario to deal with the cold start problem and to enable tailoring the system’s behavior to the needs of each individual user.
