With the help of an efficient implementation, it avoids any translation candidate selection at the document level (Resnik and Smith, 2003;Smith, 2002;Snover et al., 2008;Utiyama and Isahara, 2003;Munteanu and Marcu, 2005;Fung and Cheung, 2004).
the extraction algorithm works when no document-level information is available.
