Mining Mathematical Documents for Question Answering via Unsupervised Formula Labeling

1 code implementation12 Nov 2022 Philipp Scharpf, Moritz Schubotz, Bela Gipp

In this paper, we aim to bridge the gap by presenting data mining methods and benchmark results to employ Mathematical Entity Linking (MathEL) and Unsupervised Formula Labeling (UFL) for semantic formula search and mathematical question answering (MathQA) on the arXiv preprint repository, Wikipedia, and Wikidata, which is part of the Wikimedia ecosystem of free knowledge.

AutoMSC: Automatic Assignment of Mathematics Subject Classification Labels

1 code implementation25 May 2020 Moritz Schubotz, Philipp Scharpf, Olaf Teschke, Andreas Kuehnemund, Corinna Breitinger, Bela Gipp

Moreover, we find that the method's confidence score allows for reducing the effort by 86% compared to the manual coarse-grained classification effort while maintaining a precision of 81% for automatically classified articles.
