From: JFC Morfin jefsey@jefsey.com Thank you for this detailed explanation. How do you see the integration/impact of Wikidata on both projects?
My intuition is that the impact could be mutual: * for YAGO and DBpedia, the impact would be immediate, because Wikidata could essentially provide cleaner infobox data for these projects. Yet, we have to see how Wikidata will position itself to Freebase, which seems to pursue a similar goal: http://en.wikipedia.org/wiki/Freebase (If you have thoughts on distinguishing Wikidata from Freebase, we'd be happy to know)
* for Wikidata, there could be some leverage in the ontologies as well, possibly for bootstrapping. - YAGO, e.g., has mappings of infobox data to relations with domains and ranges, with a quality guarantee. One naive idea is that these could contribute to filling up Wikidata initially, because it seems easier for humans to correct or complete data than to insert it from scratch. - Another aspect is that YAGO connects the Wikipedia categories and pages to WordNet, the major digital lexicon of English (http://wordnet.princeton.edu/). This could contribute a strict semantic typing / class hierarchy / taxonomy to Wikidata, which is so far absent in Wikipedia. - Last, YAGO has the connection to Geonames (providing data about geographical entities), and also the connection to the Universal Wordnet (providing translations of class names and entity names to 200 other languages -- basically a cleaned and expanded version of the Wikipedia interlanguage links). - DBpedia, too, could contribute, because its hub position in the cloud of linked data connects it to many other resources.
