The Semantic Web

Related: semantic - web


The Semantic Web is a current project under the direction of Tim Berners-Lee of the World Wide Web Consortium to extend the ability of the World Wide Web by developing standards and tools that allow meaning to be added to the content of webpages. The goal of the semantic web is to create a universal medium for the exchange of data by allowing meaning to be given, using tools and tags, to the content within webpages.

Currently the world wide web contains HTML, which is a language that is useful for displaying graphics and text but does not lend any meaning to the content it describes. The semantic web will address this issue by allowing content to be described in XML documents using tools like RDF and OWL which are types of tags. These description tags that lend meaning to the content facilitates automated information gathering and research by computers.


The usability and usefulness of the Web and its interconnected resources will be enhanced through:

The primary facilitators of this technology are: URIs (which identify resources) along with XML and Namespaces. These, together with a bit of logic form RDF, which can be used to say anything about anything. As well as RDF, many other technologies such as Topic Maps and pre-web AI technologies are likely to contribute to the Semantic Web.

Semantic Web

Definition: The Semantic Web is the representation of data on the World Wide Web. It is a collaborative effort led by W3C with participation from a large number of researchers and industrial partners. It is based on the Resource Description Framework (RDF), which integrates a variety of applications using XML for syntax and URIs for naming.

"The Semantic Web is an extension of the current web in which information is given well-defined meaning, better enabling computers and people to work in cooperation." -- Tim Berners-Lee, James Hendler, Ora Lassila, The Semantic Web, Scientific American, May 2001

Towards the Semantic Web: Ontology-Driven Knowledge Management () - John Davies

  • Towards the Semantic Web: Ontology-Driven Knowledge Management () - John Davies [Amazon.com] [FR] [DE] [UK]
    With the current changes driven by the expansion of the World Wide Web, this book uses a different approach from other books on the market: it applies ontologies to electronically available information to improve the quality of knowledge management in large and distributed organizations. Ontologies are formal theories supporting knowledge sharing and reuse. They can be used to explicitly represent semantics of semi-structured information. These enable sophisticated automatic support for acquiring, maintaining and accessing information. Methodology and tools are developed for intelligent access to large volumes of semi-structured and textual information sources in intra- and extra-, and internet-based environments to employ the full power of ontologies in supporting knowledge management from the information client perspective and the information provider.
    The aim of the book is to support efficient and effective knowledge management and focuses on weakly-structured online information sources. It is aimed primarily at researchers in the area of knowledge management and information retrieval and will also be a useful reference for students in computer science at the postgraduate level and for business managers who are aiming to increase the corporations information infrastructure.
