The Semantic Web

In today's World Wide Web, information is primarily targeted at humans. Information describing resources is largely concerned with the presentation of that information rather than its content or meaning. Thus the content is, in general, inaccessible to machines and machine processing.

The Semantic Web (SW) is based on the notion of exposing metadata about resources in an explicit, machine-processable way. By doing this, we open up the possibility of using machine processing in order to help us search, organize and understand our data. Building a Semantic Web introduces requirements for languages, tools and technologies to support explicit representations of metadata and its use in applications.

Members of the Information Management Group have been at the forefront of this activity, playing key roles in bodies responsible for the production of language standards, and in developing the necessary infrastructure needed to deliver the Semantic Web. In particular, the IMG has interests in ontologies, and the technology needed to support their representation, construction, maintenance and use.

The IMG is also a keen consumer of Semantic Web technologies, making use of metadata to support activities in fields such as e-Science, Semantic Grid, Conceptual Hypermedia and Accessibility.
