Heuristic Word Alignment with Parallel Phrases
Maria Holmqvist · 2010
This paper presents a method for word alignment that uses parallel phrases from manually word aligned sentence pairs to align words in new texts.Experiments on an English-Swedish parallel corpus showed that the heuristic phrase-based method produced word alignments with high precision.Furthermore, alignment recall was improved by generalizing phrases with part-of-speech categories.We also compared the phrase-based method to statistical word alignment and found that a combination of phrase-based and statistical word alignments outperformed pure statistical alignment in terms of Alignment Error Rate (AER).
