I think we can improve upon this by supporting both xmlns:og=" http://opengraphprotocol.org/schema/"; and xmlns:fb=" http://www.facebook.com/2008/fbml"; namespaces... right now it would appear that we don't. In particular the overwhelming majority of triples coming from thus page appear to be coming from the microdata parser as they are exracted from the microdata itemProp's. One thing I've noticed is that although the HTML TitleExtract [0] is being called, the HTMLMetaExtractor [1] is not! We need to investigate this further.
