Keep all the titles of a Wikipedia internal link.

The space inside an infobox is limited and people don't give good labels in those links.
This extractor would provide better data if we kept the text links as well.

You can find provenance in the quad versions where the wikitext line is mentioned.

Regarding duplicates, I think it would be good to have them and be able to count labels stats.

I don't think this is a dataset someone want to load directly in a triple store but something that could generate other datasets with post-processing
