Initial feedback

Hi @vrandezo , I'm pasting below my first thoughts posted on the Wikidata mailing list:

1. in general, how can we compare datasets with totally different time stamps? Wikidata is alive, Freebase is dead, and the latest DBpedia dump is old;
2. given that all datasets contain Wikipedia links, perhaps we could use them as a bridge for the comparison, instead of Wikidata mappings. I'm assuming that Freebase and DBpedia entities with Wikidata mappings are subsets of the whole datasets (but this should be verified);
3. we could use record linkage techniques to connect Wikidata entities with Freebase and DBpedia ones, then assess the agreement in terms of statements per entity. There has been some experimental work (different use case and goal) in the soweego project:
