Implementation Semantic Web on E-Learning

The current WWW is a powerful tool for research and education, but its utility is hampered by the inability of the user to navigate easily the nefarious sources for the information he requires. The Semantic Web is a vision to solve this problem. It is proposed that a new WWW architecture will support not only Web content, but also associated formal semantics [4]. The idea is that the Web content and accompanying semantics (or metadata) will be accessed by Web agents, allowing these agents to reason about the content and produce intelligent answers to users’ queries.

The Semantic Web, in practice, comprises a layered framework: an XML layer for expressing the Web content; a Resource Description Framework (RDF) [8] layer for representing the semantics of the content; an ontology layer for describing the vocabulary of the domain; and a logic layer to enable intelligent reasoning with meaningful data [18].

XML was designed as a simple, flexible way of transporting structured documents across the Web. With XML, “tags”
