\textit{NewsEdits}: A Dataset of Revision Histories for News Articles (Technical Report: Data Processing)

News article revision histories have the potential to give us novel insights across varied fields of linguistics and social sciences. In this work, we present, to our knowledge, the first publicly available dataset of news article revision histories, or \textit{NewsEdits}. Our dataset is multilingual; it contains 1,278,804 articles with 4,609,430 versions from over 22 English- and French-language newspaper sources based in three countries. Across version pairs, we count 10.9 million added sentences; 8.9 million changed sentences and 6.8 million removed sentences. Within the changed sentences, we derive 72 million atomic edits. \textit{NewsEdits} is, to our knowledge, the largest corpus of revision histories of any domain.
