Fwd: [Wikimedia-l] Wikipedia in an abstract language
by Pine W 18 Jan '19

18 Jan '19

Forwarding because this (ambitious!) proposal may be of interest to people on other lists. I'm not endorsing the proposal at this time, but I'm curious about it. Pine ( https://meta.wikimedia.org/wiki/User:Pine ) ---------- Forwarded message --------- From: Denny Vrandečić <vrandecic(a)gmail.com> Date: Sat, Sep 29, 2018 at 6:32 PM Subject: [Wikimedia-l] Wikipedia in an abstract language To: Wikimedia Mailing List <wikimedia-l(a)lists.wikimedia.org> Semantic Web languages allow to express ontologies and knowledge bases in a way meant to be particularly amenable to the Web. Ontologies formalize the shared understanding of a domain. But the most expressive and widespread languages that we know of are human natural languages, and the largest knowledge base we have is the wealth of text written in human languages. We looks for a path to bridge the gap between knowledge representation languages such as OWL and human natural languages such as English. We propose a project to simultaneously expose that gap, allow to collaborate on closing it, make progress widely visible, and is highly attractive and valuable in its own right: a Wikipedia written in an abstract language to be rendered into any natural language on request. This would make current Wikipedia editors about 100x more productive, and increase the content of Wikipedia by 10x. For billions of users this will unlock knowledge they currently do not have access to. My first talk on this topic will be on October 10, 2018, 16:45-17:00, at the Asilomar in Monterey, CA during the Blue Sky track of ISWC. My second, longer talk on the topic will be at the DL workshop in Tempe, AZ, October 27-29. Comments are very welcome as I prepare the slides and the talk.

Wikidata considered unable to support hierarchical search in Structured Data for Commons
by James Heald 20 Oct '18

20 Oct '18

This recent announcement by the Structured Data team perhaps ought to be quite a heads-up for us: https://commons.wikimedia.org/wiki/Commons_talk:Structured_data#Searching_C… Essentially the team has given up on the hope of using Wikidata hierarchies to suggest generalised "depicts" values to store for images on Commons, to match against terms in incoming search requests. i.e. if an image is of a German Shepherd dog, and identified as such, the team has given up on trying to infer in general from Wikidata that 'dog' is also a search term that such an image should score positively with. Apparently the Wikidata hierarchies were simply too complicated, too unpredictable, and too arbitrary and inconsistent in their design across different subject areas to be readily assimilated (before one even starts on the density of bugs and glitches that then undermine them). Instead, if that image ought to be considered in a search for 'dog', it looks as though an explicit 'depicts:dog' statement may be going to be needed to be specifically present, in addition to 'depicts:German Shepherd'. Some of the background behind this assessment can be read in https://phabricator.wikimedia.org/T199119 in particular the first substantive comment on that ticket, by Cparle on 10 July, giving his quick initial read of some of the issues using Wikidata would face. SDC was considered a flagship end-application for Wikidata. If the data in Wikidata is not usable enough to supply the dogfood that project was expected to be going to be relying on, that should be a serious wake-up call, a red flag we should not ignore. If the way data is organised across different subjects is currently too inconsistent and confusing to be usable by our own SDC project, are there actions we can take to address that? Are there design principles to be chosen that then need to be applied consistently? Is this something the community can do, or is some more active direction going to need to be applied? Wikidata's 'ontology' has grown haphazardly, with little oversight, like an untended bank of weeds. Is some more active gardening now required? -- James. --- This email has been checked for viruses by AVG. https://www.avg.com

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>.

wikibase docker images and sitelinks
by Erik Paulson 13 Oct '18

13 Oct '18

Hello - I've got a very basic wikibase up and running, using this tutorial: https://medium.com/@thisismattmiller/wikibase-for-research-infrastructure-p… The tutorial along with the docker images make getting up and running pretty easy - So I've got a small base loaded - 7 properties, a couple of "core items", and then about 2000 jazz musicians. All seems mostly fine - I can query it via SPARQL, edit items in wikibase, and create pages in the wiki. The sample code is a touch out of date because the wikidata client library used for the examples has evolved a bit, but it wasn't too hard to figure out. However, I can't seem to create a link from the item to a page in my wiki - I don't appear to be have a site that I can link against. When I try to use this page: http://localhost:8181/wiki/Special:SetSiteLink whatever i try, it tells me that my site ID is unknown, and that I should try a known site like 'enwiki' (which also fails). I've tried just about every variation of siteID that I can think of. Trying to add a site link in the wikidata item page for an item fails too - when I try to add a link, I'm never presented with a list of sites to potentially link to in the 'Wikipedia' box (and in the wikinews/wikivoyage/etc sitelink boxes) The wikibase installation page at https://www.mediawiki.org/wiki/Wikibase/Installation#There_are_no_sites_I_c… suggests running these commands: php lib/maintenance/populateSitesTable.php php repo/maintenance/rebuildItemsPerSite.php So I docker exec'ed into the wikibase container and ran them. Now, I'm presented with site link options - but all to wikipedia.org sites, not my local site. I've tried inserting a row into the 'sites' table in MySQL to something that points to the local site, but still no dice. Can someone point me at what I'm missing? Related: the docker-compose system that comes up also brings up a regular mediawiki site, and it seemingly has the wikibase-client extension running, because I can reference my local wikibase data and pull out properties for items - for example, I can make a page for 'Teddy Edwards', and use this syntax and get a result: {{#statements:P7|from=Q1932}} P7 in the tutorial is the URL for an image from the linkedjazz site. (Teddy Edwards is assigned Q1932 in the tutorial I'm following) However, because I can't make a sitelink from http://localhost:8181/wiki/Item:Q1932 to http://localhost:8181/wiki/Teddy_Edwards. And (I think) because of the lack of that sitelink, the wikibase client only works with the |from syntax - if I put in my Teddy_Edwards article just a {{#statements:P7}} line, I get no results when it's rendered. Am I correct that this second problem is tied to my first problem? Thanks in advance for any suggestions, -Erik

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

Early 6th birthday gift: ProWD - Profiling WikiData
by Fariz Darari 04 Oct '18

04 Oct '18

Dear fellow Wikidataists, did you know that data in Wikidata about Asian countries is 100% complete for the head of government, yet is only 33% complete for the central bank? Did you know that data in Wikidata about African countries is less complete than European countries? As an early little birthday gift for the 6th Birthday of Wikidata, we are proud to release ProWD - Profiling WikiData. ProWD is a tool to analyze data completeness in Wikidata, which is based on the class (e.g., country), facet (e.g., continent), and attribute (e.g., central bank) of the entities. ProWD features: (1) Know which entity has been completed? Which has not? (2) See overall completeness of a class of entities. (3) Compare completeness between different facets of a class. ProWD is available online at https://prowd-prototype.herokuapp.com/ ProWD tutorial is available online at http://bit.ly/prowd-tut We would be very happy to have your visit to play around with ProWD. We would appreciate for any insights on how ProWD can be improved further, or how ProWD might be useful for your Wikidata projects. Warm regards, Fariz Darari On behalf of ProWD Team

Wikidata HDT dump
by Laura Morales 02 Oct '18

02 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.

Etymology of Lexemes
by Thad Guidry 30 Sep '18

30 Sep '18

I looked through the Data Model for Lexemes. Began playing around and looking at some of the existing data. Then I wondered about word origins. Example: "Neighborhood Electric Vehicle" is a phrase first coined in the 1970's. The earliest specific reference for this phrase is in the 1978 California Penal Code which could be pointed to as a reference. Is there are use case for Etymology with Lexemes ? Specifically, not just the origin of the word pointing to a previous word...through use of the existing P5191 derived from <https://www.wikidata.org/wiki/Property:P5191> property, but when a new phrase is actually introduced to the world, typically because of a Fad, Technology, etc. How would the year "1978" and the reference work "California Penal Code" be utilized for the earliest known date of usage for a phrase ? -Thad +ThadGuidry <https://plus.google.com/+ThadGuidry>
