In order to avoid any misunderstanding, we position our work as an extrinsic detection, the aim of which is to find near-matches between texts, as opposed to intrinsic detection whose aim is to show that different parts of a presumably single-author text could not have been written by the same author [Stamatatos et al 2011a], [Stein et al 2011], [Bensalem et al 2014].
our main objective is to deal with the entry level of the detection.
