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