Abstract. On the Semantic Web personalization technologies are needed to deal with user diversity. Our research aims at maximising the automation of acquisition of user knowledge, thus providing an effective solution for multi-faceted user modeling. This paper presents an approach to eliciting a user’s conceptualization by engaging in an ontology-driven dialog. This is implemented as an OWL-based domain-independent diagnostic agent. We show the deployment of the agent in a use case for personalized management of learning content, which has been evaluated in three studies with users. Currently, the system is being deployed in a cultural heritage domain for personalized recommendation of museum resources. 1
The Integration of Two Domain Conceptualizations in a Single Adaptive Hypermedia System
"... Abstract. One of the main purposes of using ontologies for knowledge modeling in adaptive systems is knowledge reuse and interoperability. Commitment of knowledge models to a common ontology can potentially help to solve a number of traditional problems found in adaptive systems, including cross-app ..."

Abstract. One of the main purposes of using ontologies for knowledge modeling in adaptive systems is knowledge reuse and interoperability. Commitment of knowledge models to a common ontology can potentially help to solve a number of traditional problems found in adaptive systems, including cross-application personalization. A new version of the adaptive educational hypermedia system QuizGuide integrates two domain models, based on different conceptualizations of C programming, and models student knowledge according to both of them. In this paper, we analyze the benefits of the integration due to the interaction of these models and discuss the forthcoming evolution of the system, based on communication with the ontology server. 1

In this paper, we present the results of an ongoing research involving the design and implementation of systems supporting personalized access to multi-version resources in an eGovernment scenario. Personalization is supported by means of Semantic Web techniques and is based on an ontology-based profiling of users (citizens). Resources we consider are collections of norm documents in XML format but can also be generic Web pages and portals or eGovernment services. We introduce a reference infrastructure, describe the organization and present performance figures of a prototype system we have developed.

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 architecture of an adaptive learning content management system. The implemented framework is illustrated 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.

Abstract. One of the most important applications of Digital Libraries (DL) is learning. In order to enable the development of eLearning applications that easily exploit DL contents it is crucial to bridge the interoperability gap between DL and eLearning applications. For this purpose, a generic interoperability framework has been developed that could also be applied to other types of applications which are built on top of DL, although this paper focuses on eLearning applications. In this context, a framework for supporting pedagogy-driven personalization in eLearning applications has been developed that performs automatic creation of personalized learning experiences using reusable (audiovisual) learning objects, taking into account the learner profiles and a set of abstract training scenarios (pedagogical templates). From a technical point of view, all the framework components have been organized into a service-oriented Architecture that Supports Interoperability between Digital Libraries and ELearning Applications (ASIDE). A prototype of the ASIDE Framework has been implemented.
