多语言应用经常涉及处理专有名词，但在双语词典中经常缺少名称。对于涉及拉丁脚本语言和亚洲语言（例如中文、日文和韩文（CJK））之间的翻译的应用程序，该问题更加严重，其中简单的字符串复制不是解决方案。我们提出了一种新的方法来产生表意文字表示的CJK名字写在拉丁字母。所提出的方法包括首先确定名称的起源，然后使用语言特定的映射将名称回译为所有可能的中文字符。为了减少大量的计算的可能性，我们应用了一个三层过滤过程，首先通过一组经证明的二元组进行过滤，然后通过一组经证明的条款，最后通过WWW进行最终验证。我们用英日回译来说明这种方法。对日本人的名字和姓氏的测试集，我们已经取得了73%和90%，分别平均精度。
Multilingual applications frequently involve dealing with proper names, but names are often missing in bilingual lexicons. This problem is exacerbated for applications involving translation between Latin-scripted languages and Asian languages such as Chinese, Japanese and Korean (CJK) where simple string copying is not a solution. We present a novel approach for generating the ideographic representations of a CJK name written in a Latin script. The proposed approach involves first identifying the origin of the name, and then back-transliterating the name to all possible Chinese characters using language-specific mappings. To reduce the massive number of possibilities for computation, we apply a three-tier filtering process by filtering first through a set of attested bigrams, then through a set of attested terms, and lastly through the WWW for a final validation. We illustrate the approach with English-to-Japanese back-transliteration. Against test sets of Japanese given names and surnames, we have achieved average precisions of 73% and 90%, respectively.
