跨语言信息检索需要良好的方法来翻译可用词典资源未涵盖的跨语言拼写变体。 FITE-TRT 是一种既定方法，采用基于频率的识别从基于转换规则的翻译中接收到的翻译等价物。本研究进一步开发和评估了 FITE-TRT 方法。该论文在四个领域做出了贡献。首先，讨论 FITE-TRT 方法的有效实现。其次，开发了一种新颖的迭代FITE-TRT翻译方法，以进一步提高该方法的有效性。第三，FITE-TRT 的有效性通过三类源-目标词相似度进行评估。 FITE-TRT 被发现在最相似的源词和目标词类别中非常强大，只有当词不相似时才变得不成功。第四，与 n-gram 和 s-gram 匹配方法相比，FITE-TRT 始终表现得更强。总而言之，在可比条件下，FITE-TRT 明显优于模糊字符串匹配方法。因此，当对结果质量要求较高时，它是识别跨语言拼写变体翻译等价物的首选方法。
Cross-language Information Retrieval requires good methods for translating cross-lingual spelling variants which are not covered by the available dictionary resources. FITE-TRT is an established method employing frequency-based identification of translation equivalents received from transformation rule based translation. This study further develops and evaluates the FITE-TRT method. The paper contributes on four areas. First, an efficient implementation for the FITE-TRT method is discussed. Secondly, a novel iterative FITE-TRT translation approach is developed in order to further improve the effectiveness of the method. Thirdly, the effectiveness of FITE-TRT is assessed in three classes of source-target word similarity. FITE-TRT was found to be very strong in the class of the most similar source and target words and only becomes unsuccessful when the words were dissimilar. Fourthly, in comparison to n-gram and s-gram matching methods, FITE-TRT is shown consistently stronger. All in all, FITE-TRT clearly outperforms the fuzzy string matching methods under comparable conditions. Therefore it is the method of choice for the identification of translation equivalents of cross-lingual spelling variants when the requirements for the result quality are high.
