Ontology and Description Logic for E-Learning

Abstract

A semantic web is a web environment in which users and computer agents interact semantically. Users need to put their queries exactly as they want; its goal is to make accurate content available. When the machine is capable of answering all questions, it will provide the precise answer as well as a list of hyperlinks. In the semantic web, ontologies serve as a data model for describing the concepts and relationships that exist between them. In this the content is annotated with meta tags to provide useful meaning and allow humans and machines to collaborate. This chapter describes the semantic web and how it can be useful in the case of e-learning. It gives the architecture of a semantic-based conceptual e-learning portal and highlights the importance of ontology in the field of education. Description logic is an integral part of the generation of well-formed datasets. This chapter integrates DL to ontologies.
