[Wikidata-l] Wikidata turns two!
Hey folks :) Today Wikidata is turning two. It amazes me what we've achieved in just 2 years. We've built an incredible project that is set out to change the world. Thank you everyone who has been a part of this so far. We've put together some notes and opinions. And there are presents as well!

[Wikidata-l] Birthday gift: Missing Wikipedia links (was Re: Wikidata turns two!)
Folks, as you know, many Googlers are huge fans of Wikipedia. So here’s a little gift for Wikidata’s second birthday. Some of my smart colleagues at Google have run a few heuristics and algorithms in order to discover Wikipedia articles in different languages about the same topic which are missing language links between the articles. The results contain more than 35,000 missing links with a high confidence according to these algorithms. We estimate a precision of about 92+% (i.e. we assume that less than 8% of those are wrong, based on our evaluation). The dataset covers 60 Wikipedia language editions. Here are the missing links, available for download from the WMF labs servers: https://tools.wmflabs.org/yichengtry/merge_candidate.20141028.csv The data is published under CC-0. What can you do with the data? Since it is CC-0, you can do anything you want, obviously, but here are a few suggestions: There’s a small tool on WMF labs that you can use to verify the links (it displays the articles side by side from a language pair you select, and then you can confirm or contradict the merge): https://tools.wmflabs.org/yichengtry The tool does not do the change in Wikidata itself, though (we thought it would be too invasive if we did that). Instead, the results of the human evaluation are saved on WMF labs. You are welcome to take the tool and extend it with the possibility to upload the change directly on Wikidata, if you so wish, or, once the data is verified, to upload the results. Also, Magnus Manske is already busy uploading the data to the Wikidata game, so you can very soon also play the merge game on the data directly. He is also creating the missing items on Wikidata. Thanks Magnus for a very pleasant cooperation! I want to call out to my colleagues at Google who created the dataset - Jiang Bian and Si Li - and to Yicheng Huang, the intern who developed the tool on labs. I hope that this small data release can help a little with further improving the quality of Wikidata and Wikipedia! Thank you all, you are awesome!

Re: [Wikidata-l] Wikidata RDF
Martynas, Denny is right. You could set up a Virtuoso endpoint based on our RDF exports. This would be quite nice to have. That's one important reason why we created the exports, and I really hope we will soon see this happening. We are dealing here with a very large project, and the decision for or against a technology is not just a matter of our personal preference. If RDF can demonstrate added value, then there will surely be resources to further extend the support for it. So far, we are in the lead: we provide close to one billion (!) triples Wikidata knowledge to the world. So far, there is no known use of this data. We need to go step by step: some support from us, some practical usage from the RDF community, some more support from us, ... In reply to your initial email, Martynas, I have to say that you seem to have very little knowledge about what is going on in Wikidata. If you would follow the development reports more closely, you would know that most of the work is going into components that RDF does not replace at all. Querying with SPARQL is nice, but we are still more focussed on UI issues, history management, infrastructure integration (such as pushing changes to other sites), and many more things which are completely unrelated to RDF in every way. Your suggestion that a single file format would somehow magically make the construction of one of the world-largest community-edited knowledge bases a piece of cake is just naive. Now don't get me wrong: naive thinking has it's place in Wikidata -- it's always naive to try what others consider impossible -- but it should be combined with some positive, forward thinking attitude. I hope that our challenge to show the power of RDF to us can unleash some positive energies in you :-) I am looking forward to your results (and happy to help if you need some more details about the RDF dumps etc.).

Re: [Wikidata-l] Wikidata RDF
FWIW, put me in the camp of people who want to see wikidata available via RDF as well. I won't argue that RDF needs to be the *native* format for Wikidata, but I think it would be a crying shame for such a large knowledgebase to be cut off from seamless integration with the rest of the LinkedData world. That said, I don't really care if RDF/SPARQL support come later and are treated as an add on, but I do think Wikidata should at least have that as a goal for eventually. And if I can help make that happen, I'll try to pitch in however I can. I have some experiments I'm doing now, working on some new approaches to scaling RDF triplestores, so using the Wikidata data may be an interesting testbed for that down the road. And on a related note - and apologies if this has been discussed to death, but I haven't been on the list since the beginning - but I am curious if there is any formal collaboration (in-place|proposed|possible) between dbpedia and wikidata?
