Chao Wang, Dequan Zheng, Tiejun Zhao, Ji Guo · 2011
Mining bilingual parallel sentence pair from Web data is the most effective way to get large-scale of bilingual corpus. In this paper, we put forward both the set of method and the series of process for extracting parallel sentence pair from nonspecific web date source. considering 1.1 billion page as the web data input, with a sequence of steps we get several sentences pair which has 81% recall and 85% precision, on this basis we bring up a parameter for measure quality of sentence pair. After filter sentence pair by this parameter, we get 850 thousand unique sentence pairs. On filtering by this parameter, the precision increase to 95%, meanwhile the recall only decrease by 1%.
