Automatic compilation of lexicon is a dream of lexicon compilers as well as lexicon users. This paper proposes a system that crawls English-Japanese person-name transliterations from the Web, which works a back-end collector for automatic compilation of bilingual person-name lexicon. Our crawler collected 561K transliterations in five months. From them, an English-Japanese person-name lexicon with 406K entries has been compiled by an automatic post processing. This lexicon is much larger than other similar resources including English-Japanese lexicon of HeiNER obtained from Wikipedia. Categories and Subject Descriptors I.2.7 [Artificial Intelligence]: Natural Language Processing; H.3.3 [Information Storage and Retrieval]: Information Search and Retrieval General Terms Algorithms, Design, Experimentation.
