Yash Nagar completed an internship with Wikimedia Deutschland working on his master's thesis about harvesting mathematical formulas from Wikipedia and integrating them into Wikidata to make them available to question answering systems. This helped significantly enrich Wikidata's data and make it more useful for users. Wikimedia Deutschland is a non-profit organization based in Berlin that is the oldest and largest independent chapter of the Wikimedia movement, supporting the free online encyclopedia Wikipedia and other projects. Lydia Pintscher of Wikimedia Deutschland recommends Yash Nagar and his work during his internship.
