Supporting Learner Model Exchange in Educational Web Systems

چکیده
The heterogeneity of learner models in structure, syntax and semantics makes sharing them a significant challenge for existing educational web systems. Creating mappings between the different types of learner models is one technique that is used when attempting to overcome these issues. This paper presents an overview of research currently being conducted in the area of learner model exchange and defines a categorization, derived from existing educational web systems, of the different mapping types that are required for learner model mapping. Following this, a framework is presented that supports the creation and validation of these different mapping types and the exchange of learner information between multiple heterogeneous educational web systems.

A generic component for exchanging user models between web-based systems
Educational web-based systems exemplify the increasing need for personalisation. Applications that adapt to individual users need a model of the user that contains as accurate data as possible. On the web, learners use multiple educational systems and spend their time over many applications: these are individually limited in their user modelling but can gain from joining forces. This boils down...
متن کاملProposed Approach to Build Semantic Learner Model in Adaptive E-Learning
In the context of E-learning, adaptive systems are more specialized and focus on the adaptation of learning content and the presentation of this content. The adaptive E-learning system focuses on how the profile data is learned by the learner and pays attention to learning activities, cognitive structures and the context of the learning material. The system controls the process of collecting da...
متن کاملLearner Modeling on the Semantic Web
Learners are assessed by several systems during their lifelong learning. Those systems can maintain fragments of information about a learner derived from his learning performance and/or assessment in that particular system. Customization services would perform better if they would be able to exchange as many relevant fragments of information about the learner as possible. This paper presents th...

The goal of the semantic web is to facilitate the exchange of meaningful information in a form that is easy for machines to process. The goal of an e-learning system is to support the learning process by providing meaningful information for students in a form that best suits them. Natural synergies between these two areas have led to a surge in the feasibility of user modelling and intelligent ...
متن کاملPersonalized Web - Based Learning 2 . 0
Educational content was among the first appearing on the Web. This applies not only for the " Read Web " presented as the Web 1.0, but also for the Adaptive Web with main concern on the personalization to each learner. Even though this is not true for the Social Web, or the Web 2.0, educational domain gets in the " Read-Write Web " too. This paper presents selected aspects of web-based educatio...
