Symbol string conversion method, word translation method, its device, its program and recording medium
TL;DR: In this article, a word translation device 5B is provided with: a word output part 5 for preparing a database by referring to a transliteration probability model 7, and using approximation under the consideration of a word set maximizing conditioned probability with the character history of the word set as conditions, and for retrieving a second word corresponding to an input first word; a conversion candidate retrieving part 40 for outputting a third word extracted from document data acquired by electronic equipment 50 connected to a communication network NW based on the first word as a convert candidate to the second word; and a conversion possibility
