ACL Anthology Reference Corpus (ACL ARC) is a collection of 10,920 academic papers from the ACL Anthology. ACL ARC is cleaned to remove:

• files that look like not full papers, paper fragments, foreign-language papers (e.g., French), or pure junk.
• headers (title and author information; NOT abstract).
• footers ("References" line and the actual references).
• some bad characters (spurious characters).
• some page numbers (i.e., a single number appearing on a line, with nothing else attached to it).
• significant foreign-language (e.g., French) content in an otherwise English paper.

The cleaned corpus has 10,628 documents.
