Apertium-sme-eng for WMT2026 shared task—creating new pair by crossing dictionaries and translating rules

Flammie Pirinen


Abstract
In this article I describe an experiment on creation of a new rule-based machine translation model build on two existing models. I built Apertium system between North Sámi and English based on existing translation models between North Sámi and Finnish, and Finnish and English. There were two expert-driven processes involved in building of the system: firstly crossing and validating the bilingual dictionaries and secondly translating and modifying the grammatical and structural rules. I breifly explain why there are no pre-existing systems for this language pair and what limitations and ethical issues are related to it. I will also evaluate some of the training and development corpora provided in the shared task to elaborate on the problem that automatic low quality machine translation can cause to vulnerable minority languages.
