Extracting Grammatical Error Corrections from Wikipedia Revision History

This paper describes the process of extracting and filtering Wikipedia revision history as a resource 14 grammatical error correction (GEC). Edits in Wikipedia revision history vary widely, including grammatical error corrections, information supplements, format amendments, and even vandalism. To extract only GEC-related revisions, we use an automated error annotation toolkit, ERRANT(1), and extend it to process large data in parallel efficiently. With error-type analysis, we can then identify GEC-related edits and omit other unrelated edits (i.e., only the correction parts are reserved). The resulting corpus is - to our knowledge - the largest publicly available corpus of parallel possibly erroneous and correct sentences with error type labels.
