I feel lucky re: autotagging
I experimented with an automatic-tagging experiment/engine tonight. The designer cleverly used Wikipedia’s URIs as a source for a controlled concept/tagging vocabulary! Pretty cool. He full-text indexed Wikipedia (yes, he downloaded it all) with Lucene, (an open source search engine), and used its, “I feel lucky,” feature to make tag/concept associations.
As input I experimented with text from Bob’s first slide from the last lecture:
Overview of the Semantic Web RDF OWL A Critical Evaluation of the Semantic Web Semantically-aware systems

There’s too much output to post here, but you get a tiered-list of potential tags. I found the third-tier results pretty interesting. I could imagine this being useful (though imperfect) for automatically adding keyword/tag metadata to a document.
..So someone could develop a blog plugin that automatically generates tags based on this..
