Translated Texts Under the Lens: From Machine Translation Detection to Source Language Identification

Anonymous

Abstract: In this work, we tackle the problem of the detection of translated texts from different angles. On top of addressing the classic task of machine translation detection, we investigate and find the presence of common patterns across different machine translation systems as well as different source languages. Then, we show that it is possible to identify the translation systems used to produce a translated text (F1-score $88.5\%$) as well as the source language of the original text (F1-score $79\%$).We assess our tasks using Books, a new dataset we built from scratch based on excerpts of novels and the well-known Europarl dataset.
