MathMex: Search Engine for Math Definitions

This paper introduces MathMex, an open-source search engine for math definitions. With MathMex, users can search for definitions of mathematical concepts extracted from a variety of data sources and types including text, images, and videos. Definitions are extracted using a fine-tuned SciBERT classifier, and the search is done with a fine-tuned Sentence-BERT model. MathMex interface provides means of issuing a text, formula, and combined queries and logging features.
