Anonymous Coward writes "A research group at University of Maryland has published a blog describing the latest approach for finding and indexing Semantic Web Documents. They have published it in reaction to Peter Norvig's (director of search quality at Google) view on the Semantic Web (Semantic Web Ontologies: What Works and What Doesn't): 'A friend of mine [from UMBC] just asked can I send him all the URLs on the web that have dot-RDF, dot-OWL, and a couple other extensions on them; he couldn't find them all. I looked, and it turns out there's only around 200,000 of them. That's about 0.005% of the web. We've got a ways to go.'"
