Lexical token alignment: experiments, results and applications
Dan Ioan Tufis, Ana-Maria Barbu · 2002
Lexical alignment is one of the most challenging tasks in processing and exploiting parallel texts.There are numerous applications that may benefit from an accurate multilingual lexical alignment of bi-and multi-language corpora.We describe in this paper a hypothesistesting approach to the problem of automatic extraction of translation equivalents from sentence-aligned and tagged parallel corpora.The algorithm was used for automatic extraction of 6 bi-lingual lexicons with English as source language and Bulgarian, Czech, Estonian, Hungarian, Romanian and Slovene as the target one, as well as a 7-language lexicon with English as a hub and the other 6 CEE languages.For the experiments described here we used the 7-language aligned corpus based on Orwell's "1984" novel.
