arXiv:2601.18026v2 Announce Type: replace Abstract: Language identification (LID) is a fundamental step in curating multilingual corpora. However, LID models still perform poorly for many languages, especially on the noisy and heterogeneous web data often used to train multilingual language models. In this paper, we introduce CommonLID, a community-driven, human-annotated LID benchmark for the web domain, covering 109 languages. Many of the included languages have been previously under-served, making CommonLID a key resource for developing more representative high-quality text corpora. We show
The proliferation of multilingual web data and the limitations of current language identification models on noisy web content necessitate a new benchmark to improve foundational AI capabilities.
Improved language identification directly enhances the quality of multilingual AI models, crucial for global data processing and the development of more inclusive and accurate AI systems.
The availability of CommonLID provides a standardized, human-annotated benchmark for 109 languages, enabling more robust evaluation and development of LID models, especially for previously under-served languages.

- · Multilingual data curators
- · Developers of global AI products
- · Users of less common languages
- · AI models reliant on uncurated, noisy multilingual data
- · Entities with limited access to high-quality language datasets
More accurate language identification will lead to higher quality multilingual training datasets for large language models.
Improved multilingual datasets will enable better performance of AI models across a broader range of languages, fostering more equitable AI development.
Enhanced global AI capabilities could reduce linguistic barriers, accelerating cross-cultural information exchange and technological integration.
