Automatic Construction of a Sense-disambiguated Multilingual Dictionary

开发了一种新的方法，用于从现有的一组双语词典中生成多语言词典，这是多语言机器翻译和信息检索所必需的。基于从文本语料库中提取的它们的上下文之间的相似性来判断具有一个或多个共同翻译的不同语言的两个词是否是彼此的真正翻译。通过在英日、英汉双语词典和日汉报刊语料库中生成英日汉三种语言词典的实验，取得了83%的准确率和73%的F-Score。

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.
