Lately I've merged Wikipedia usage information with DBpedia information to produce a subjective importance score:
https://github.com/paulhoule/telepath/wiki/SubjectiveEye3D
That particular product has two layers of processing that can be done independently: one is averaging over time, the other is reconciling the {project,page URI} tuples to concepts. In the case of DBpedia, the main thing that happens is that importance is summed up for all of the redirects that point to a particular concept.
The product linked above was built with the English Dbpedia, but it ought to be easy to do the same thing with a different ?lang Dbpedia, and get products that reflect the point of view of different ?lang zones.
I don't see redirect data in Wikidata, so it seems that redirects should be processed against DBpedia of all languages and then these should be merged with the contents of the "Wikipedia pages linked to this Item" that I see on a page like this:
http://www.wikidata.org/wiki/Q1631090
does this make sense? What's the easy way to get bulk access to that information? Who else wants to see this happen?
