| 摘 要： | 对词计算第三步模糊约束重译进行了研究.指出了候选词汇对应的模糊子集和结果约束中的模糊子集之间的贴近度和包容度在获取可信重译结果中的重要性.给出了分离算子的概念并设计了一个满足要求的分离算子.在此基础上定义了包容度的概念并给出了重译指数的计算公式.提出了一种基于重译指数计算的模糊约束重译方法.最后用实例说明了该方法的有效性.

| Abstract: | Constraint retranslation,the third step of Computing with Words,is explored in this paper.The importance of closeness degree and containment degree between the fuzzy subset of candidate words and the fuzzy subset of result constraint in geting logical retranslation result is pointed out.The conception of separation operator is presented and a desired separation operator is designed.Then the conception of containment degree is defined and the computational formula for retranslation weight is presented.A method of constraint retranslation based on computation of retranslation weight is proposed. Finally,some examples are given to illustrate the validity of the proposed method. |
