RDF Topicmaps

The RDF Topicmaps project offers software that extracts noun phrases and simple thesaurus-like relationships from web pages and packages them in RDF. The distribution is comprised of the following components:

  • web page harvester, which also extracts metadata from pages and normalizes their content
  • topicmap generator, using the normalized content as input
  • web based interface to the topicmaps

Please see the RDF Topicmaps Project Page for more information.
