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.

All the best Moritz
