Machine Translation System for Numeral in English Text to Yorùbá Language

The machine translation of numbers from the English language into the Yorùbá language is an integral part of a machine translation system from the English language into the Yorùbá language as a numeral system is an important aspect of any language. This paper presents a computational approach to English number text translation into Yorùbá text. The approach shows the number of ways an English number text can be translated into the Yorùbá language and the various forms in which the translations can be done based on context. This was carried out by collecting numeral data from the Yorùbá literature, formulating context-free grammar, and implementing the model with the Python programming language. The evaluation of the system was carried out using the Bilingual Evaluation Understudy (BLEU) score. The result of the approach is a software artefact for translating number text in the context of simple English sentences to Yorùbá text. They can further be integrated as a module into a robust machine translation system for effective and accurate translation from the English language to the Yorùbá language.
