Semantic Search Points To Better Relevancy
ReadWriteWeb writes in to tell us about an article by Dr. Riza C. Berkan, founder and CEO of hakia.com, describing the promise of and potential for semantic search. This approach to providing more on-target search results contrasts with the dream of the semantic Web. Semantic search doesn't require all the Web page authors in the world to begin adding metadata; but it's not a sure thing that the researchers now developing the idea will get it right.
You're confusing the word "metadata" with the HTML tag . In this case (the semantic web) metadata would be in RDF. More clues here. What TFA is proposing is to semantically process and index websites content, rather than have the websites (or a third party) tag the content with RDF. What both of them are lacking is any kind of a universal ontology (or even standardized specialty ontologies).
No folly is more costly than the folly of intolerant idealism. - Winston Churchill
