Ambiguity is a common phenomenon in natural language. In the course of communication between human beings, the ambiguity problem is not a great trouble because of the help of human intelligence. Therefore, it's not a problem to human translation of natural language. But for the machine who contains little intelligence, the ambiguous sentences begins to appear in a large scale and be a fundamental obstacle to machine translation . Statistics shows that a MT system with a welldefined syntactic rules produces 2. 8 parsing trees per sentence when English 900 is processed, and the average lexical ambiguity is 2. 5. Even though the property that language distribution is comparatively uneven have been taken into consideration, the probability to generate a correct daily-used sentence is below 40%.

歧义是自然语言中一个非常普遍的现象，在人们使用语言的过程中，由于人的特殊智能机制的存在，歧义并没有对理解构成太多的问题，因而也就没有对语言的翻译构成实质性的问题，但是，在基本上不具备智能机制的机器面前，歧义现象开始大量表现并对机器翻译构成威胁，实际统计表明，一个良好定义的语法分析系统在分析英语900句时，平均句法歧义2.8次，平均词汇歧义2.5次，即使考虑到句法及译义出现的概率的不均匀性，如果不作任何消歧处理，译对常用句子的可能性将低于40%，因此，解决机器翻译的歧义问题已成为众矢之的。
