Abstract

Mathematical formulae are a foundational component of information in all scientific and mathematical papers. Parsing meaning from these expressions by extracting textual descriptors of their variable tokens is a unique challenge that requires semantic and grammatical knowledge. In this work, we present a new manually-labeled dataset (called the MTDE dataset) of mathematical objects, the contexts in which they are defined, and their textual definitions. With this dataset, we evaluate the accuracy of several modern neural network models on two definition extraction tasks. While this is not a solved task, modern language models such as BERT perform well (∼ 90%). Both the dataset and neural network models (implemented in PyTorch jupyter notebooks) are available online to help aid future researchers in this space.
