Shaoqi Wang, Miao Li, Zede Zhu, Zhenxin Yang, Shizhuang Weng · 2014
In this paper, we propose a novel method to optimize translation candidate lists derived from window-based approach for the task of bilingual lexicon extraction. The optimizing process consists of two cross-comparisons between 1 th translation candidate of each target word, and between set of all the 1 th candidates and that of each word’s 2 th to N th ones. Experiment results demonstrate that the proposed method leads to a significant improvement on accuracy over window-based approach in bilingual lexicon extraction from both English-Chinese and Chinese-English comparable corpora.
