The most important thing Sherman is trying to do is provide an alternative interface to <http://lod.openlinksw.com> and validate the prowess of the REST API that was built to address the challenge known as: Web Scale Faceted Browsing :-) As per my response to David earlier, more interesting revelations to come next week.

For example, searching Monopoly, then filtering to the umbel-sc:MentalSituations category gave me a nice (and in some cases humorous) list of Monopoly knock-offs. I tried finding such a list on the WWW with no luck <http://www.google.com/search?q=Monopoly%20knockoffs> . Kingsley tells me that Entity Rank [4] has to do with this, but I wonder whether this quality will stick as the cloud increases. >> >> >> References: >> [1] http://simile.mit.edu/wiki/Longwell >> [2] http://mqlx.com/~david/parallax/ >> [3] http://ec2.monrai.com:8890/facets >> [4] http://lod.openlinksw.com/fct/facet_doc.html >> [5] http://lod.openlinksw.com >> [6] http://cypher.monrai.com >> >> Enjoy, >> >> >> >> > > > -- > > > Regards, > > Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen > President & CEO > OpenLink Software Web: http://www.openlinksw.com > > > > > > > -- Regards, Kingsley Idehen Weblog: http://www.openlinksw.com/blog/~kidehen President & CEO OpenLink Software Web: http://www.openlinksw.com
