Evaluation of Dictionary Creating Methods for Under-Resourced Languages

摘要

In this paper, we present several bilingual dictionary building methods applied for Northern Saami-{English, Finnish, Hungarian, Russian} language pairs. Since Northern Saami is an under-resourced language and standard dictionary building methods require a large amount of pre-processed data, we had to find alternative methods. In a thorough evaluation, we compared the results for each method, which proved our expectations that the precision of standard lexicon building methods is quite low. The most precise method is utilizing Wikipedia title pairs extracted via inter-language links, but Wiktionary-based methods also provided useful result.
