Semantic Web Topic Hierarchy

This page describes the taxonomy of Semantic Web topics adopted by the European projects Knowledge Web (http://knowledgeweb.semanticweb.org) and REWERSE (http://rewerse.net) and maintained by Joerg Diederich.

We also collected Emerging Semantic Web Topics not yet being included in the hierarchy because there is either no consensus in the community or it has not found a significantly critical mass of papers/workshops/etc.

This version is 2.0. Version 1.1 is available here: (http://semanticweb.org/index.php?title=Semantic_Web_Topic_Hierarchy&oldid=32243), version 1.0, the first one publicly announced on kweb-all can be seen here: ( http://semanticweb.org/index.php?title=Semantic_Web_Topic_Hierarchy&oldid=9657 ). The changes and versions of the topic hierarchy are summarized on the page History of the Semantic Web Topic Hierarchy.

The taxonomy is available as a SKOS vocabulary ( http://www.l3s.de/kweb/swth/swth_skos_v2.0.rdf ). It is also available in OWL as an extension of the SWRC ontology (see http://ontoware.org/projects/swrc/ -> swrc-swtopics) (currently version 1.1 only).
