Abstract:
1. A method comprising: identifying boundaries for a phrase in a source sentence by requiring that a source word be aligned with at least one target word in a target sentence in order to form a boundary of a source phrase; identifying boundaries for a phrase in the target sentence based on alignments between words in the source phrase and words in the target sentence; determining if the source phrase and target phrase form a phrase alignment pair by determining if any of the words of the target phrase are aligned with source words outside of the source phrase; if a target word in the target phrase is aligned with a source word outside of the source phrase, a processor excluding a contiguous span of source words as a possible source phrase for phrase alignment pairs without identifying boundaries for a target phrase corresponding to the contiguous span if the contiguous span shares a common boundary with the source phrase, does not include the source word that is outside of the source phrase, and includes all of the words of the source phrase; and storing the source phrase and the target phrase if they form a phrase alignment pair.
