Students from University of Wuppertal enable linking of formulae and Wikibase items using the VisualEditor
by Moritz Schubotz 01 Jun '22

01 Jun '22

Dear Community Group Math, as an applied project in the Information Retrieval Lecture [1] at the University of Wuppertal offered by gipplab [2] students implemented a new feature for Wikipedia that simplifies the linking of formulae and Wikidata items. As described in [3, Section 2] it was possible to link Wikidata items with formulae in Wikipedia since 2020. However, this linking was only possible when using the source code editor. Now, one can link the Wikidata item and the formulae visually (see screenshot attached). The Wikibase ID beginning with Q identifies an item in the knowledge graph that contains additional semantics for the formulae which can subsequently be used to improve accessibility or search for mathematical formulae. Currently, the workflow is that one has to search for the Wikibase ID which describes the formulae best and copy that id into the new field in the form. To eliminate this context switch, the student team will improve the user experience further by providing auto-completion so that the formula name can be entered rather than the id. Another group is focused on automating this process even further and suggesting suitable ids based on the AnnoMathTex [4] transforming the manual task of assigning ids into a supervised machine learning task. However, this feature will require a special setup and not be enabled by default for all users of Wikipedia.

Fwd: BOT Election: Affiliate representative information needed.
by Physikerwelt 20 May '22

20 May '22

Hi all, Is anyone interested in voting? --> Please contact me All the best moritz (physikerwelt) ---------- Forwarded message --------- From: Youngjin Ko <yko-ctr(a)wikimedia.org> Date: Fri, May 20, 2022 at 6:02 AM Subject: BOT Election: Affiliate representative information needed. To: <andre.greiner-petter(a)t-online.de>, Moritz Schubotz <wiki(a)physikerwelt.de> Dear Affiliate, I am reaching out to you today about the upcoming affiliate involvement in the Board of Trustees election. The opportunity to ask questions to candidates is coming soon. The affiliate voting period is from 1 - 15 July. During that time, each affiliate is allowed one vote to shortlist the group of 13 candidates to 6. Each affiliate must identify one person to represent the affiliate question and voting phase. This representative will pose the questions the affiliate might have to ask the candidates and will cast the vote on behalf of the affiliate organization. Please reply to this email letting us know who your representative is. Please do this by 30 May 2022. We need the username, their email address and which affiliate they will be representing. Unfortunately, representatives cannot represent more than one affiliate in this election. Be sure the username provided is correct because these usernames will be entered into SecurePoll for voting. Without the correct information, the user will not be able to vote or will be delayed in voting. Key dates to remember 30 May 2022 - Deadline to submit your affiliate representative’s username and email address. (If you cannot submit this information by May 30, let us know). June 2022 - Representatives ask candidates questions and review answers to inform their vote. The Analysis Committee publishes their ratings of candidates to inform voters. 1 - 15 July 2022 - Representatives vote in the Affiliate voting period. Best, -- Youngjin Ko (he/him) Movement Strategy and Governance facilitator Wikimedia Foundation

Wikimedia Community User Group Math Progress
by Physikerwelt 28 Jan '22

Dear Math(ML) enthusiasts, mathematical expressions are essential building blocks for the representation of mathematical knowledge in Wikimedia Projects and elsewhere. To coordinate the maintenance and development of tools relevant to the global mathematical community the Wikimedia Community Group Math [1] was established in 2019. Ultimately, the group's mission is to decide on pragmatic steps towards the goal of making mathematical knowledge easily accessible to every human being. In 2021, some implementation details of the caching mechanism of the Math rendering pipeline had been updated to the latest software development paradigms employed in Wikimedias codebase. In addition, Wikimedia joined the W3C MathML working to pave the ground for native and accessible Math rendering in browsers without workarounds like images or special text formatting to match mimic math rendering. For 2022, the goal is to further simplify the rendering process of mathematical expressions and to continue the work on the MathML 4 standard [2]. Moreover, we aim to facilitate more active participation in discussing the next steps in Math-related developments for Wikimedia projects. Therefore, we strive to further maximize our geographical and gender diversity. In contrast to 2021, where most improvements remain under the hood of the Math extension codebase [3], in 2022, there are even a few achievements this year. - We have a new Wikimedia hosted mailing list math(a)lists.wikimedia.org (if you were subscribed to the old mailing list, you should have been transferred to the new mailing list) - Math is now bundled within the default distribution of MediaWiki [4] - The rendering of \omicron was fixed If you receive this email but you did not sign up for any of the mailing lists in the recipient list, you might be in the BCC field and want to subscribe to our new mailing list [5];-) All the best André and Moritz [1]: https://meta.wikimedia.org/wiki/Wikimedia_Community_User_Group_Math [2]: https://www.w3.org/Math/Documents/Charter2021.html [3]: https://github.com/wikimedia/mediawiki-extensions-Math/graphs/contributors [4]: https://phabricator.wikimedia.org/T232948 [5]: https://lists.wikimedia.org/postorius/lists/math.lists.wikimedia.org/ -- https://schubotz.org | +49 1578 047 1397
