The Semantic Web: What, Why, How, and When
Found in: IEEE Distributed Systems Online
By Frank van Harmelen
Issue Date:March 2004
pp. 4
<p>The Semantic Web aims to enrich the Web with a layer of machine-interpretable metadata so that computer programs can predictably derive new information. This goal will require the development of metadata syntax and vocabularies, and the creation o...
 
OIL: An Ontology Infrastructure for the Semantic Web

Currently, computers are changing from single isolated devices to entry points into a worldwide network of information exchange and business transactions. Support in the exchange of data, information, and knowledge is becoming the key issue in computer tec...
 
The Semantic Web: The Roles of XML and RDF
Found in: IEEE Internet Computing
By Stefan Decker, Sergey Melnik, Frank Van Harmelen, Dieter Fensel, Michel Klein, Jeen Broekstra, Michael Erdmann, Ian Horrocks
Issue Date:September 2000
pp. 63-74
<p>XML and RDF are the current standards for establishing semantic interoperability on the Web, but XML addresses only document structure. RDF better facilitates interoperation because it provides a data model that can be extended to address sophisti...
 
Ontology-Based Information Visualisation
