Hi, You might find http://backlinks.psi.enakting.org/ interesting; it extracts backlinks, often combining with sameas.org (which is itself of course a specialist backlinking service). It also has an option to enable geographical containment as an implied backlink.
I suspect that what was true of the text web will be true of the web of data for much the same reasons.
