... Because the SCFG rules are labeled with non- terminals composed from both the source and tar- get trees, the nonterminal inventory is quite large, leading to estimation difficulties. To deal with this, we automatically ... See full document

... To calculate language model (LM) features, we train traditional n-gram language models with n- gram lengths of four and five using the SRILM toolkit (Stolcke, 2002). We calculate our features using the KenLM toolkit ... See full document
