We take advantage of the assumption that where a chunk contains just one non-marker word in both source and target, these words are translations of each other.
where a marker-headed pair contains just two words, as in (16), for instance, we can extract the word-level translations in 23 using the marker hypothesis method of segmentation, smaller aligned segments can be extracted from the phrasal lexicon without recourse to any detailed parsing techniques or complex co-ocurrence measures.
