Generate (meta)data from unstructured data

• Another (emerging) approach:

• • use Natural Language Processing (NLP) to analyze text
  • generate “meta” data (eg, tags) automatically in, say, RDF
  • some systems do it “behind the scenes” (eg, Twine)
  • some offer public web services that can be incorporated in, say, blogging software (eg, Reuter’s Open Calais)
