Automating Formalization by Statistical and Semantic Parsing of Mathematics

We discuss the progress in our project which aims to automate formalization by combining natural language processing with deep semantic understanding of mathematical expressions. We introduce the overall motivation and ideas behind this project, and then propose a context-based parsing approach that combines efficient statistical learning of deep parse trees with their semantic pruning by type checking and large-theory automated theorem proving. We show that our learning method allows efficient use of large amount of contextual information, which in turn significantly boosts the precision of the statistical parsing
and also makes it more efficient. This leads to a large improvement of our first results in parsing theorems from the Flyspeck corpus.
