Sentence Compression takes an important place for Natural Language Processing (NLP) tasks where specific constraints must be satisfied, such as length in summarization (Barzilay & Lee, 2002; Knight & Marcu, 2002; Shinyama et al., 2002;<cite> Barzilay & Lee, 2003</cite>; Le Nguyen & Ho, 2004; Unno et al., 2006) , style in text simplification (Marsi & Krahmer, 2005) or sentence simplification for subtitling (Daelemans et al., 2004) .
