Naturally-occurring instances of linguistic phenomena are important both for\ntraining and for evaluating automatic processes on text. When available in\nlarge quantities, they also prove interesting material for linguistic studies.\nIn this article, we present a new resource built from Wikipedia's revision\nhistory, called WiCoPaCo (Wikipedia Correction and Paraphrase Corpus), which\ncontains numerous editings by human contributors, including various corrections\nand rewritings. We discuss the main motivations for building such a resource,\ndescribe how it was built and present initial applications on French.\n
