Comparing and Extracting Paraphrasing Words with 2-Way Bilingual Dictionaries
Kazutaka Takao, Kenji Imamura, Hideki Kashioka · 2002
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.
