我们利用双向双语词典分析了各种词汇表达，并提出了一种提取释义词的方法。首先，我们从英译日再译回英语的角度比较了英日词典和日英词典的覆盖率。通过举例说明了这一变化。接下来，我们提出了一种自动提取英语释义词组的方法；我们收集了E-J词典中具有相同日语翻译单词的英语索引词。然后将母语为日语的人难以区分的英语单词提取到释义组中。我们还提取了日语释义词组进行比较。这种方法将对句子匹配有用，特别是为了接受各种表达方式。
We analyze a variety of lexical expressions with 2-way bilingual dictionaries and propose a method for extracting paraphrasing words. First, we compare the coverage between an English-Japanese dictionary and a Japanese-English dictionary from the viewpoint of the returnability of the words by translating English to Japanese, and then back to English again. The variety is shown using examples. Next, we propose a method of automatically extracting English paraphrasing word groups; we gathered the English index words which have the same Japanese translation words in the E-J dictionary. The English words which are difficult to distinguish for native speakers of Japanese were then extracted into a paraphrasing group. We also extract the Japanese paraphrasing word groups for comparison. This method will be useful for sentence matching, especially in order to accept the variety of expressions.
