A personalized learning experience is possible withthe use of learner models in intelligent tutoring systems. adaptive educational hypermediasystems and semantic webbased learning environments. Although there are standards to overcome complexities or lack of fulfilling user needs (such as, IEEE or IMS), these models are either too generic or too complex to handle. In addition, there are various alternative learner or user models in the literature. Yet, these models do not address how to model learning object (LO) based instructional systems. therefore, in this paper, an ontology based learner model is proposed for e-learning systems which use instructional learning objects.
Recommender systems have emerged as a way to tackle the overload of information reected in the increasing volume of information artefacts in the web and elsewhere. Recommender systems analyse existing information on t...

A service-based approach to link annotation expands the applicability of adaptive navigation support functionality beyond the limits of traditional adaptivehypermediasystems. Withthis approach, the decision-making functionality is separated from the application systems and encapsulated in a personalization service. this paper attempts to evaluate the feasibility of using this approach in the real world. After a brief overview of current efforts to develop service-based approaches to adaptivehypermedia, we describe our specific implementation of this approach as personalization architecture and report the results of an extensive performance evaluation of this architecture.

adaptivehypermedia and Intelligent Tutoring systems are both used for computer-based instruction, but their strengths lie in different areas. adaptivehypermedia is better suited to the instruction of concepts, while Intelligent Tutoring systems generally assist in the use of these concepts to solve problems. A general instruction system requires both of these methods of instruction to provide a full learning environment. this paper describes a proposed method of combining adaptivehypermedia and Intelligent Tutoring systems using Knowledge Spaces, a method of mathematically modeling a domain.

this paper presents an approach to achieve User Model (UM) interoperability exploiting web Service technologies for syntactic interoperability, and Semantic web languages for semantic interoperability, together with negotiation techniques based on dialogue. We propose a SOA-based framework where a central UDDI registry, enhanced with UM specific capabilities, is used to support and promote the cooperation between UM-based applications.

web browsing is a complex activity and in general, users are not guided during browsing. the aim of this research is to support the browsing of users using semantic and adaptive hyperlinks using Semantic web technologies and personalization methods. In this paper, we propose a novel Semantic web browser (Semweb), which uses a behavior-based and an ontology-driven user modeling architecture. In our approach, semantic links and adaptivehypermedia can be achieved on different websites. In addition, user profiles can be easily updated with semantic metadata coming from the Semantic web browser.

this paper presents an approach to exploit widely used tag annotations to address two important issues in user-adaptivesystems: the cold-start problem and the integration of distributed user models. the paper provides an example of re-use of user interaction data (tags) generated by one application into another one in similar domains for providing cross-system recommendations.

In this paper we present a rule-based personalization framework for encapsulating and combining personalization algorithms known from adaptivehypermedia and recommender systems. We show how this personalization framework can be integrated into existing systems by example of the educational online board Comtella-D, which exploits the framework for recommending relevant discussions to the users. In our evaluations we compare different recommender strategies, investigate usage behavior over time, and show that a small amount of user data is sufficient to generate precise recommendations.
