Wikidata dumps failed for this week
by Ryan Kemper 18 Sep '20

18 Sep '20

Hi all, Following a refactoring of some of our weekly wikidata dump jobs, we had an issue where a stale cron entry was still hanging around, which competed with the new dump cronjobs. After having discovered the issue we've fixed the root cause, but this week's dumps were unable to complete as a result. New dumps will be available this upcoming week at the usual time(s).

[Significant Change] lib/WikibaseLib.php is no longer an entry point to the Lib extension
by Mohammed Sadat Abdulai 16 Sep '20

16 Sep '20

*(Apologies for cross-posting)* Hi all, This is an announcement of a significant change to 3rd party Wikibase installs that still use lib/WikibaseLib.php as an entry point. *On September 30*, we will remove the lib/WikibaseLib.php file from the Wikibase code. Wikis which directly load that file in their LocalSettings.php will then fail to load (after the 1.36 release of MediaWiki and Wikibase, if they do not track the master branch). The file lib/Wikibase.php used to be the entry point of the WikibaseLib extension. Directly loading this file has not been necessary since the earliest days of Wikibase – it was loaded automatically by the entry points of the Client and Repo extensions. Nevertheless, lines similar to the following found their way into some Wikibase installation instructions: require_once "$IP/extensions/Wikibase/lib/WikibaseLib.php"; If your LocalSettings.php contains such a line, please remove it. It has not been needed for ages, and soon it will stop working. This refactoring is part of a project with a twofold objective: (1) decouple the Wikibase Client and Repo as much as possible and establish a long-term strategy for organising the shared logic <https://doc.wikimedia.org/Wikibase/master/php/adr_0013.html>, and (2) get both Client and Repo to use the standard extension registration mechanism <https://www.mediawiki.org/wiki/Special:MyLanguage/Manual:Extension_registra…> to be loaded. The impact of the project is focused on developers who can now have a clearer view of the code, the modules involved, and their interactions which makes their lives easier. Also, the maintenance of the code is now easier. This is the phabricator board <https://phabricator.wikimedia.org/project/profile/4815/> of the project. If you have any issues or questions, please do not hesitate to ask. Cheers, -- Mohammed Sadat *Community Communications Manager for Wikidata/Wikibase* Wikimedia Deutschland e.V.

Edit history-revisions
by Elisavet Koutsiana 15 Sep '20

15 Sep '20

Hello, I wanted to ask if there is any canonical way to identify deletion, reverts etc in the edit history xml files. I can understand that the action of every revision is described in the "comment" element of the xml format, but is there a code name or number or anything else that will help me to identify one revision for example as deletion? Thank you, Elisavet

Evolution of the community communications roles for Wikidata
by Léa Lacroix 11 Sep '20

11 Sep '20

Hello all, For the past four years, I’ve been working in the software department at Wikimedia Germany, taking care of the communication between the Wikidata development team <https://www.wikidata.org/wiki/Wikidata:DEV> and the community, announcing new features, collecting bug reports and feature requests from you. On top of that, I’ve been coordinating various projects, bringing the WikidataCon <https://meta.wikimedia.org/wiki/Grants:Conference/WMDE/WikidataCon/Report#I…> to life, coordinating the Wikidata decentralized birthday <https://www.wikidata.org/wiki/Wikidata:Eighth_Birthday>, creating a prototype for Wikidata Train the Trainers <https://www.wikidata.org/wiki/Wikidata:Train_the_trainers>, and taking care of various onsite or online workshops, meetups and other events. Over the past years, with the Wikidata community growing, the development team growing as well, more and more events happening, and the ecosystem of Wikibase users forming a distinct group with different needs, it became pretty clear that one person was not enough to keep track of everything and provide the best support for the Wikidata editors. That’s the reason why, earlier this year, we had the pleasure to announce the arrival of a new colleague who you already know from being an active Wikidata editor, Mohammed Sadat (WMDE) <https://www.wikidata.org/wiki/User:Mohammed_Sadat_(WMDE)>. We already started a smooth transition of our roles: while Mohammed will become the main person in charge of community communications for the Wikidata and Wikibase communities, I will focus more on organizing Wikidata-related events and supporting community members with their own events and projects. As you may have noticed, Mohammed already took over editing the weekly newsletter <https://www.wikidata.org/wiki/Wikidata:Status_updates/Next>, monitoring the social media, and various announcements for Wikidata and Wikibase. As for myself, I will not disappear completely from the Wikidata channels: I will keep supporting Mohammed on community communication, for example with projects like the Wikidata Bridge <https://www.mediawiki.org/wiki/Wikidata_Bridge>, in which I’ve been involved since the start. During this transition phase, we will review and improve our existing communication processes, and you can for example give feedback on the experience you had while reporting bugs or feature requests <https://www.wikidata.org/wiki/Wikidata:Contact_the_development_team/Process…>. Feel free to reach out to Mohammed if you have any questions regarding Wikidata’s development roadmap <https://www.wikidata.org/wiki/Wikidata:Development_plan>. I’m looking forward to continuing working with you on various projects: feel free to contact me if you want to discuss Wikidata-related events, training, online events, or any other ideas you have in mind to gather the Wikidata community and onboard new editors.

[ANN] DBpedia Autumn Hackathon, starting Sept 21st
by Sebastian Hellmann 11 Sep '20

11 Sep '20

Apologies for cross-posting Dear DBpedians, Linked Data savvies and Ontologists, We would like to invite you to join the DBpedia Autumn Hackathon 2020 as a new format to contribute to DBpedia, gain fame, win small prizes and experience the latest technology provided by DBpedia Association members. The hackathon is part of the Knowledge Graphs in Action conference on October 6, 2020. Please check here: https://wiki.dbpedia.org/meetings/KnowledgeGraphsInAction # Timeline * Registration of participants - main communication channel will be the #hackathon channel in DBpedia Slack (sign up https://dbpedia-slack.herokuapp.com/, then add yourself to the channel). If you wish to receive a reminder email on Sep 21st, you can leave your email address in this form: https://tinyurl.com/y24ps5jt * Until September 14th - preparation phase, participating organisations prepare details, track formation, additional tracks can be proposed, please contact dbpedia-events(a)infai.org <mailto:dbpedia-events@infai.org> * September 21st - Announcement of details for each track, including prizes, participating data, demos, tools and tasks. Check updates on hackathon website https://wiki.dbpedia.org/events/dbpedia-autumn-hackathon-2020 * September 21st to October 1st - hacking period, coordinated via DBpedia slack * October 1st, 23:59 Hawaii Time - Submission of hacking result (3 min video and 2-3 paragraph summary with links, if not stated otherwise in the track) * October 5th, 16:00 CEST - Final Event, each track chair presents a short recap of the track, announces prizes or summarizes the result of hacking. * October 6th, 9:50 - 15:30 CEST - Knowledge Graphs in Action Event * Results and videos are documented on the DBpedia Website and the DBpedia Youtube channel. # Member Tracks The member tracks are hosted by DBpedia Association members, who are technology leaders in the area of Knowledge Engineering. Additional tracks can be proposed until Sep 14th, please contact dbpedia-events(a)infai.org <mailto:dbpedia-events@infai.org>. * timbr SQL Knowledge Graph: Learn how to model, map and query ontologies in timbr and then model an ontology of GDELT, map it to the GDELT database, and answer a number of questions that currently are quite impossible to get from the BigQuery GDELT database. Cash prizes planned. https://www.timbr.ai/ * GNOSS Knowledge Graph Builder: Give meaning to your organisation’s documents and data with a Knowledge Graph. https://www.gnoss.com/en/products/semantic-framework * ImageSnippets: Labeling images with semantic descriptions. Use DBpedia spotlight and an entity matching lookup to select DBpedia terms to describe images. Then explore the resulting dataset through searches over inference graphs and explore the ImageSnippets dataset through our SPARQL endpoint. Prizes planned. http://www.imagesnippets.com * Diffbot: Build Your Own Knowledge Graph! Use the Natural Language API to extract triples from natural language text and expand these triples with data from the Diffbot Knowledge Graph (10+ billion entities, 1+ trillion facts). Check out the demo http://demo.nl.diffbot.com/. All participants will receive access to the Diffbot KG and tools for (non-commercial) research for one year ($10,000 value). # Dutch National Knowledge Graph Track Following the DBpedia FlexiFusion approach, we are currently flexi-fusing a huge, dbpedia-style knowledge graph that will connect many Linked Data sources and data silos relevant to the country of the Netherlands. We hope that this will eventually crystallize a well-connected sub-community linked open data (LOD) cloud in the same manner as DBpedia crystallized the original LOD cloud with some improvements (you could call it LOD Mark II). Data and hackathon details will be announced on 21st of September. # Improve DBpedia Track A community track, where everybody can participate and contribute in improving existing DBpedia components, in particular the extraction framework, the mappings, the ontology, data quality test cases, new extractors, links and other extensions. Best individual contributions will be acknowledged on the DBpedia website by anointing the WebID/Foaf profile. (chaired by Milan Dojchinovski and Marvin Hofer from the DBpedia Association & InfAI and the DBpedia Hacking Committee) # DBpedia Open Innovation Track (not part of the hackathon, pre-announcement) For the DBpedia Spring Event 2021, we are planning an Open Innovation Track, where DBpedians can showcase their applications. This endeavour will not be part of the hackathon as we are looking for significant showcases with development effort of months & years built on the core infrastructure of DBpedia such as the SPARQL endpoint, the data, lookup, spotlight, DBpedia Live, etc. Details will be announced during the Hackathon Final Event on October 5. (chaired by Heiko Paulheim et al.) Stay tuned and stay safe! With kind regards, The DBpedia Organizing-Team

WDQS / WCQS Status update
by Guillaume Lederrey 08 Sep '20

08 Sep '20

Hello all! A quick update on what's going on around our SPARQL endpoints. * Wikimedia Commons Query Service (WCQS) [1] is available as a beta service. We've seen a number of people starting to run queries. And a number of examples have been added [2]. Thanks all for your help! * We are focusing again on WDQS and improving the update process [3]. So far, we have an end-to-end working example for simple updates (revision create) and are working on adding support for more complex updates (deletes, undeletes, suppressed deletes, etc...). Once this all process is complete and working for WDQS, we'll see how we can adapt it for WCQS and have streaming updates to WCQS. * We are looking into the deployment constraints for the new WDQS update process. Managing Flink at scale is non trivial, we are just starting, but there is a lot more work to make this robust. * We are planning to spend more time doing some analytics on our data [4]. We want to better understand the use cases and the data we have. We are still defining exactly what question we want to answer from the data, but the main ones are ** What are the most expensive queries, what are they trying to achieve and is that reasonable ** Do we have performant subgraphs that we could expose indepently. This will also require some work to improve our query logging and aggregate more context with the queries we log. That's all for today! Have fun!

RDF embedded in Wikipedia pages Discussion Space?
by Kingsley Idehen 08 Sep '20

08 Sep '20
