GippLab Showcases Research to DAAD President at NII Tokyo

wp-editor — Fri, 24 Oct 2025 17:11:56 +0000

GippLab members Dr. André Greiner-Petter and Dr. Timo Spinde had the honor of meeting Prof. Joybrato Mukherjee, President of the German Academic Exchange Service (DAAD), during his visit to the National Institute of Informatics (NII) in Tokyo. During the meeting, our researchers presented their current research projects to highlight GippLab’s ongoing activities at the NII and the long-standing history of our successful collaboration.

The discussion, also attended by Prof. Shigeo Sugimoto, Acting Director-General of the NII, underscored the strong academic and cultural ties between German and Japanese research institutions. The DAAD President’s visit emphasized the significance and enduring success of this international partnership, which has been generously supported by the DAAD for over a decade.

Our cooperation with the NII offers students and early-career researchers at the University of Göttingen unique opportunities for research stays in Tokyo. Details are available at https://gipplab.uni-goettingen.de/tokyo.

The GippLab team is delighted to share the news that Philipp Scharpf has successfully defended his Ph.D. dissertation titled Mathematical Entity Linking: Methods and Applications.

Philipp’s research has opened new perspectives for the field of Mathematical Information Retrieval, rightfully earning him the title of Dr. rerum naturalium.

Join us in celebrating Dr. Scharpf’s significant achievement and in wishing him continued success in all his future endeavors.

Wikipedia rolls out our research on providing semantic information for mathematical formulae

wp-admin — Fri, 10 Jan 2020 09:00:45 +0000

As of January 9, Wikipedia allows semantically enhancing mathematical formulae with the definitions of the terms they contain. For example, the formula of the famous mass-energy equivalence E=mc² now contains information on the variables E, m, and c. Clicking on the formula opens an information page (see figure) that displays the meanings of the variables and links to additional specifications of the formula’s terms.

Our group members André-Greiner Petter and Moritz Schubotz developed this new feature as part of the research for the DFG grant GI 1259-1. The additional information on formulae is obtained from Wikidata – a central, language-independent Wikimedia database that can be edited by both humans and bots. To further improve the availability of mathematical semantics, we combine the power of artificial intelligence with the capabilities of humans to (semi-automatically) generate semantic markup for mathematics in Wikipedia. Please refer to the following publications for details and join the Wikimedia Math community group if you are interested in helping to improve math support in Wikipedia.

Improved math rendering in Wikipedia

wp-admin — Tue, 31 May 2016 08:11:34 +0000

Wikipedia is using a new approach for rendering mathematical formulae – as of May 31st. This approach was developed by our group member Moritz Schubotz.

Bitmap images representing formulae, were replaced with a combination of MathML (the web standard for mathematics on the web), in addition to a fallback mechanism for browsers that do not support this web standard.

This approach makes formulae machine readable and accessible to users with limited vision, while also looking crisper on high resolution displays and in print.
