| Research Abstract |
A novel method was developed for producing a multilingual dictionary, which is indispensable for multilingual machine translation and information retrieval, from a set of existing bilingual dictionaries. Whether two words in different languages having one or more translations in common are genuinely translations of one another is judged based on the similarity between their contexts extracted from text corpora. Its effectiveness was demonstrated through an experiment on producing an English-Japanese-Chinese trilingual dictionary from English-Japanese and English -Chinese bilingual dictionaries and Japanese and Chinese newspaper corpora, in which 83% precision and 73% F-score were attained.
