Enhancing Machine Translation for Lesser-Resourced Languages through Bilingual Informants

This paper presents novel approaches in machine translation for lesser-resourced languages, particularly highlighting the importance of linguistic structure and bilingual informants. We explore methods for unsupervised induction of paradigm morphology, allowing for the identification of morphological structures essential for effective translation. Additionally, we report on the efficacy of syntactic rule induction and refinement tools, showcasing successful applications from English to Spanish and Mapudungun to Spanish. Our findings reinforce the role of linguistic data in improving translation systems for underrepresented languages.
