It has been shown so far that using transliteration rules to extract Japanese Katakana and English word pairs is highly useful and promising.But for Japanese-French pairs, the method is not guaranteed to work, because only a very few Japanese Katakana words are borrowed directly from French.In this paper we will show the possibility of extracting Japanese Katakana and French w ord pairs based on transliteration from loosely aligned Japanese French bilingual corpora.The method applies all the existing transliteration rules to each mora unit in a Katakana word, and extracts the French word which matches or partially-matches one of these transliteration candidates as translation.For instance, if we h a ve `グラフ' in the Japanese part of a bilingual corpora, we generate such transliteration candidates as , , ,... and identify similar words from French part of the corpora.The method performed reasonably well, achieving 80% precision at 20% recall.We had also observed that Japanese-English transliteration rules worked well for extracting Katakana-French w ord pairs.
