%X In this paper we present a framework that can be used to generate web-based, semantically adaptive, e-learning and computer-assisted assessment (CAA) tools for any given knowledge domain, based upon dynamic ontological modeling. We accomplish this by generating ¡°learning ontologies¡± for a given knowledge domain. The generated learning ontologies are built upon our previous work on a domain ¡°Glossary¡± ontology and augmented with additional conceptual relations from the WordNet 3.0 lexical database, using Text2Onto, an open source ontology extraction tool. The main novelty of this work is in ¡°on the fly¡± generation of computer assisted assessments based on the underlying ontology and pre-defined question templates that are founded on the Bloom¡¯s taxonomy of educational objectives. The main deployment scenario for the framework is a web-service providing collaborative e- learning and knowledge management capabilities to various learning communities. The framework can be extended to provide collection and exploitation of the users¡¯ learning behaviour metrics, in order to further adapt the generated e-learning environment to the learners¡¯ needs.
