arXiv:2606.06088v1 Announce Type: new Abstract: We present CHALIS (Challenging Language Identification Samples), a new benchmark dataset explicitly designed to address difficult cases in language identification: cousin languages and orthographic noise. Our dataset has two parts: First, we collected sentences shared across mutually intelligible language pairs (Czech/Slovak, Spanish/Catalan, Portuguese/Galician, Danish/Norwegian). The second part tests for orthography noise: we transliterate text across multiple scripts, remove diacritics, simulate homoglyph attacks, and use Internet slang. We e
The proliferation of multilingual data and sophisticated AI models makes robust language identification increasingly critical to avoid misinterpretations and improve model performance.
This dataset improves the ability of AI systems to accurately identify languages in complex, real-world scenarios, which is crucial for cross-lingual communication, content moderation, and sovereign AI initiatives.
The availability of CHALIS will lead to more resilient and accurate language identification models, particularly for challenging linguistic variances and noisy, informal text.

Improved accuracy in language identification tools across various applications becomes possible.
Enhanced cross-lingual understanding and reduced communication barriers in digital spaces may emerge.
This could contribute to the development of more sophisticated, culturally nuanced AI models capable of operating effectively across diverse linguistic contexts.
