All you can do is offer access to a data space that let's the user Find what they seek via disambiguation oriented filters. Examples: 1. http://uriburner.com/fct/facet.vsp?cmd=load&fsq_id=81 -- Pattern: Person that may or may not be associated with a Class or Property 2. http://uriburner.com/fct/facet.vsp?cmd=load&fsq_id=82 -- Pattern: Person associated with a Class (explicitly) 3. http://uriburner.com/fct/facet.vsp?cmd=load&fsq_id=83 -- Pattern: Person associated with a Transitive Property. In all cases above, when happy click on Entity1 or EntityN (too see and access descriptions of matching entities) depending on where you're at in your quest. Of course, you can switch "uriburner.com" for "lod.openlinksw.com" and do the same thing against an even larger data set etc.. -- Regards, Kingsley Idehen President& CEO OpenLink Software Web: http://www.openlinksw.com Weblog: http://www.openlinksw.com/blog/~kidehen Twitter/Identi.ca: kidehen
