Adaptive open corpus e-learning аnd authoring, using collaborative ontology learning

Adaptive e-learning systems are better for achieving many learning goals, but adaptive content development is more difficult and expencive. The open-corpus model enable use and reuse of many external resources to facilitate development process and ensure well-organized actual and personalized learning content. The main idea of this paper is controlled extension of previously developed by professionals learning course in the learning process by learners. We propose conceptual model and evaluation example of adaptive e-learning system, including easy-to-use tools, allowing users to find needed in the learning process external content and adding them as semantically described new learning resources in the system. The added content may be then checked and changed by other users - learners or teachers. The system propose tools not only for finding, manipulation, annotation and organization of the new content, but it ensure the enrichment of it described schema (ontology) by using interactive ontology learning.
