Bootstrapping Unsupervised Bilingual Lexicon Induction
Bradley D. Hauer, Garrett Nicolai, Grzegorz Kondrak · 2017
The task of unsupervised lexicon induction is to find translation pairs across monolingual corpora.We develop a novel method that creates seed lexicons by identifying cognates in the vocabularies of related languages on the basis of their frequency and lexical similarity.We apply bidirectional bootstrapping to a method which learns a linear mapping between context-based vector spaces.Experimental results on three language pairs show consistent improvement over prior work.
