In this paper,a new algorithm is proposed based on accidence analysis: the word-alignment problem is transformed to an iterative solution of anchor word-pair by multi-level match and disambiguity algorithm which only use a bilingual dictionary.

• 文章在词法分析的基础上；利用有限的语言资源(主要只使用了一部双语词典)；采取多级匹配和消歧策略；将词对齐问题转化为迭代求解锚点词对的过程；使得词对齐既有较高的准确率又有较高的召回率.
