Christopher Gutteridge of the University of Southampton recently suggested that SemanticTweet could support a semantically stable notion of twitter hash tags. I’ve recently implemented and deployed a new version of ST that does just that.

So now, you can use a URI such as:

http://semantictweet.com/tags/%23semantictweet

to represent the #semantictweet hash tag, or

http://semantictweet.com/tags/%23semantictweet+%23rdf

to represent the pair of hash tags #semantictweet and #rdf. When dereferenced, SemanticTweet will return the following RDF/XML document:

<rdf:RDF>
  <foaf:PersonalProfileDocument rdf:about="">
    <foaf:maker rdf:resource="http://semantictweet.com/semantictweet"/>
    <admin:generatorAgent rdf:resource="http://semantictweet.com/"/>
    <admin:errorReportsTo rdf:resource="mailto:stephen@flinter.com"/>
  </foaf:PersonalProfileDocument>
  <skos:Concept rdf:about="http://semantictweet.com/tags/%23semantictweet+%23rdf">
    <skos:prefLabel>#semantictweet #rdf</skos:prefLabel>
    <rdfs:seeAlso rdf:resource="http://search.twitter.com/search?q=%23semantictweet+%23rdf"/>
    <rdfs:seeAlso rdf:resource="http://search.twitter.com/search.atom?q=%23semantictweet+%23rdf"/>
    <rdfs:seeAlso rdf:resource="http://search.twitter.com/search.json?q=%23semantictweet+%23rdf"/>
  </skos:Concept>
  <foaf:Document rdf:about="http://search.twitter.com/search?q=%23semantictweet+%23rdf">
    <dc:format>text/html</dc:format>
  </foaf:Document>
</rdf:RDF>
