Is It Navajo? Accurate Language Detection in Endangered Athabaskan Languages
This work addresses the underrepresentation of endangered Native American languages in NLP systems, contributing to cultural bias mitigation and language preservation efforts, though it is incremental as it builds on existing classification methods.
The study tackled the problem of language detection for endangered Athabaskan languages, specifically Navajo, by evaluating Google's LangID tool and introducing a random forest classifier that achieved near-perfect accuracy (97-100%) and showed robustness across other languages in the family.
Endangered languages, such as Navajo - the most widely spoken Native American language - are significantly underrepresented in contemporary language technologies, exacerbating the challenges of their preservation and revitalization. This study evaluates Google's Language Identification (LangID) tool, which does not currently support any Native American languages. To address this, we introduce a random forest classifier trained on Navajo and twenty erroneously suggested languages by LangID. Despite its simplicity, the classifier achieves near-perfect accuracy (97-100%). Additionally, the model demonstrates robustness across other Athabaskan languages - a family of Native American languages spoken primarily in Alaska, the Pacific Northwest, and parts of the Southwestern United States - suggesting its potential for broader application. Our findings underscore the pressing need for NLP systems that prioritize linguistic diversity and adaptability over centralized, one-size-fits-all solutions, especially in supporting underrepresented languages in a multicultural world. This work directly contributes to ongoing efforts to address cultural biases in language models and advocates for the development of culturally localized NLP tools that serve diverse linguistic communities.
