LDC provides extracted parallel texts extracted with the algorithm published by<cite> (Munteanu and Marcu, 2005)</cite> . This corpus contains 1.1M sentence pairs (about 35M words) which were automatically extracted and aligned from the monolingual Arabic and English Gigaword corpora, a confidence score being provided for each sentence pair. We also applied our approach on data provided by LDC, but on a different subset.
