  We introduce S2ORC, a large corpus of 81.1M English-language academic papers
spanning many academic disciplines. The corpus consists of rich metadata, paper
abstracts, resolved bibliographic references, as well as structured full text
for 8.1M open access papers. Full text is annotated with automatically-detected
inline mentions of citations, figures, and tables, each linked to their
corresponding paper objects. In S2ORC, we aggregate papers from hundreds of
academic publishers and digital archives into a unified source, and create the
largest publicly-available collection of machine-readable academic text to
date. We hope this resource will facilitate research and development of tools
and tasks for text mining over academic text.
