... 1998; Tufis and Barbu, 2002). However, All of these methods require a large-scale bilingual corpus for training. When the large-scale bilingual corpus is not available, some researchers use ... to improve word alignments for general words and the corpus in the specific domain for domain-specific words. In other words, we will adapt the word alignment information in the gener...
