Dear somayeh, The alignment table is obtained starting from the intersection of IBM Model 4 source-to-target and target-to-source alignments. Then, several heuristics are used to add links from the union (of IBM Model 4 source-to-target and target-to-source alignments) not present in the intersection. The "grow-diag" heuristics add links which are neighbours, in the alignment matrix, of the links present in the current alignment table. The "final" heuristic adds links which (i) are not neighbour of any link already present in the alignment table, and (ii) for which the associated source OR target word is unlinked The "final-and" heuristic adds links which (i) are not neighbour of any link already present in the alignment table, and (ii) for which the associated source AND target words are unlinked
See http://aclweb.org/anthology-new/N/N03/N03-1017.pdf Does this answer your question ?
