The created tree nodes are labeled by the non-terminals described in section 3 . Using the initial target U-trees , source sentences and word alignment , we extract minimal GHKM translation rules7 in terms of frontier nodes ( Galley et al. , 2004 ) . Frontier nodes are the tree nodes that can map onto contiguous substrings on the source side via word alignment .
