Help us teaching ORES how to better detect vandalism
by Léa Lacroix 18 Oct '18

18 Oct '18

Hello all, As you may know, ORES is a tool analyzing edits to detect vandalism, providing a score per edit. You can see the result on Recent Changes, you can also let us know when you find something wrong <https://www.wikidata.org/wiki/Wikidata:ORES/Report_mistakes/2018>. But do you know that you can also directly help ORES to improve? We just launched a new labeling campaign <https://labels.wmflabs.org/ui/wikidatawiki/>: after authorizing your account with OAuth, you will see some real edits, and you will be asked if you find them damaging or not, good faith or bad faith. Completing a set will take you around 10 minutes. The last time we run this campaign was in 2015. Since then, the way of editing Wikidata changed, some vandalism patterns as well (for example, there are more vandalism on companies). So, if you're familiar with the Wikidata rules and you would be willing to give a bit of time to help fighting against vandalism, please participate <https://labels.wmflabs.org/ui/wikidatawiki/> :) If you encounter any problem or have question about the tool, feel free to contact Ladsgroup <https://www.wikidata.org/wiki/User:Ladsgroup>.

Wiki PageID
by Gintautas Sulskus 05 Oct '18

05 Oct '18

Hi, I have a couple of questions regarding the Wiki Page ID. Does it always stay unique for the page, where the page itself is just a placeholder for any kind of information that might change over time? Consider the following cases: 1. The first time someone creates page "Moon" it is assigned ID=1. If at some point the page is renamed to "The_Moon", the ID=1 remains intact. Is this correct? 2. What if we have page "Moon" with ID=1. Someone creates a second-page "The_Moon" with ID=2. Is it possible that page "Moon" is transformed into a redirect? Then, "Moon" would be redirecting to page "The_Moon"? 3. Is it possible for page "Moon" to become a category "Category:Moon" with the same ID=1? Thanks, Gintas

Wikidata HDT dump
by Laura Morales 03 Oct '18

03 Oct '18

Hello everyone, I'd like to ask if Wikidata could please offer a HDT [1] dump along with the already available Turtle dump [2]. HDT is a binary format to store RDF data, which is pretty useful because it can be queried from command line, it can be used as a Jena/Fuseki source, and it also uses orders-of-magnitude less space to store the same data. The problem is that it's very impractical to generate a HDT, because the current implementation requires a lot of RAM processing to convert a file. For Wikidata it will probably require a machine with 100-200GB of RAM. This is unfeasible for me because I don't have such a machine, but if you guys have one to share, I can help setup the rdf2hdt software required to convert Wikidata Turtle to HDT. Thank you.

Machine translation efforts for underserved languages
by Olya Irzak 05 Sep '18

05 Sep '18

Dear Wikidata community, We're working on a project called Wikibabel to machine-translate parts of Wikipedia into underserved languages, starting with Swahili. In hopes that some of our ideas can be helpful to machine translation projects, we wrote a blogpost about how we prioritized which pages to translate, and what categories need a human in the loop: https://medium.com/@oirzak/wikibabel-equalizing-information-access-on-a-bud… Rumor has it that the Wikidata community has thought deeply about information access. We'd love your feedback on our work. Please let us know about past / ongoing machine translation related projects so we can learn from & collaborate with them. Best regards, Olya & the Wikibabel crew

Wikidata's sixth birthday: now is the good time to start organizing it
by Léa Lacroix 22 Aug '18

22 Aug '18

Hello all, As previously announced, the sixth birthday of Wikidata will happen around October 29th, all around the world: local groups, communities, can organize their own event around Wikidata. Meetup or workshop, talk or editathon, now is the good time to start thinking about what you want to do. Wikidata's sixth birthday <https://www.wikidata.org/wiki/Wikidata:Sixth_Birthday> and its talk page is the main place where you can find information about organization, funding, and discuss with others. As mentioned in the past, WMDE can help with providing advice on organization and communication, and can send Wikidata swag to your group before the event. If we want to get all of this ready for you before the end of October, we need some buffer time. That's why I'd like to inform you about two things: 1. A *call for all organizers* or people thinking about organizing a birthday celebration, will take place on August 28th. This is the opportunity to chat with me, but also people from other local groups, about your ideas, your questions, your needs. - Date: *August 28th*, 18:00 to 19:00 (UTC+2, Berlin time) - Meeting link: Google Meet <https://meet.google.com/bxb-kgsa-tfu> (yes, it's Google. If you're deeply unhappy about this, you can write to me and we'll find another solution) 2. The *deadline for requesting Wikidata swag is September 7th*. After this date, we can't promise that we'll be able to prepare the swag for you. - Before this date, you can write me an email, listing everything you need. It can be items that we already have (T-shirts, hoodies, socks, stickers, bags, notebooks, pens...) but also other things, if you have nice ideas on what to print. - I'll reply to you shortly and we'll discuss about the best options to get the swag: print it from our usual partners in Germany, print it locally, etc. I'll support you during the whole process. If you have any question, suggestion, feel free to write to me at any time. I'm excited about the plans we're going to build together!

Indexing all item properties in ElasticSearch
by Stas Malyshev 16 Aug '18

16 Aug '18

Hi! Today we are indexing in ElasticSearch almost all string properties (except a few) and select item properties (P31 and P279). We've been asked to extend this set and index more item properties (https://phabricator.wikimedia.org/T199884). We did not do it from the start because we did not want to add too much data to the index at once, and wanted to see how the index behaves. To evaluate what this change would mean, some statistics: All usage of item properties in statements is about 231 million uses (according to sqid tool database). Of those, about 50M uses are "instance of" which we are already indexing. Another 98M uses belong to two properties - published in (P1433) and cites (P2860). Leaving about 86M for the rest of the properties. So, if we index all the item properties except P2860 and P1433, we'll be a little more than doubling the amount of data we're storing for this field, which seems OK. But if we index those too, we'll be essentially quadrupling it - which may be OK too, but is bigger jump and one that may potentially cause some issues. So, we have two questions: 1. Do we want to enable indexing for all item properties? Note that if you just want to find items with certain statement values, Wikidata Query Service matches this use case best. It's only in combination with actual fulltext search where on-wiki search is better. 2. Do we need to index P2860 and P1433 at all, and if so, would it be ok if we omit indexing for now? Would be glad to hear thoughts on the matter. Thanks, -- Stas Malyshev smalyshev(a)wikimedia.org

Wikidata in the LOD Cloud
by Léa Lacroix 13 Aug '18

13 Aug '18

Hello all, Thanks to Lucas who filled the necessary requirements, Wikidata now appears in the LOD cloud graph: http://lod-cloud.net Currently, the graph doesn't display all the actual connections of Wikidata. The only connections that show up are the properties that link to other projects or databases, and having a specific statement on them to link to an RDF endpoint. If you see something missing, you can contribute by adding the statement “formatter URI for RDF resource” on properties where the resource supports RDF (example <https://www.wikidata.org/wiki/Property:P214#P1921>). You can learn more about the procedure to update the graph and a list of the existing and missing datasets here <https://www.wikidata.org/wiki/User:Lucas_Werkmeister_(WMDE)/LOD_Cloud>, Thanks to Lucas and John for making this happening! -- Léa Lacroix Project Manager Community Communication for Wikidata Wikimedia Deutschland e.V.

NCI Thesaurus ID links not working
by Thad Guidry 07 Aug '18

07 Aug '18

Hello esteemed team ! Someone noted on Property Talk about https://www.wikidata.org/wiki/Property_talk:P1748 that an external id should be used ? I added just a few codes to test what is happening, and the CODE on the left does populate, like this one for Death https://www.wikidata.org/wiki/Q1931388 it shows my newly added C28554 on the left under External properties, but yeah, it is not a clickable link. The Formatter URL does indeed work when populated with that C28554 code...so... What could be the issue with the CODE not displaying with the Formatter URL and being clickable ? -Thad
