GlotLID-M is a Language Identification (LID) model that supports 1665 languages, including low-resource languages. It addresses challenges such as inaccurate corpus metadata, leakage from high-resource languages, difficulty distinguishing closely related languages, macrolanguage vs. varieties handling, and handling noisy data. GlotLID-M outperformed several baseline models in terms of accuracy and can be easily incorporated into datasets.
Introducing GlotLID: An Open-Source Language Identification (LID) Model that Supports 1665 Languages
In today’s globalized world, linguistic inclusion is crucial for effective communication across national boundaries. Natural language processing (NLP) technology should be accessible to a wide range of languages, including low-resource languages. However, existing language identification (LID) systems have limitations when it comes to supporting low-resource languages, which hinders linguistic diversity and inclusivity.
To address these challenges, a team of researchers has developed GlotLID-M, a unique Language Identification model. With an impressive identification capacity of 1665 languages, GlotLID-M significantly improves coverage compared to previous research. This model is a major step towards enabling a wider range of languages and cultures to benefit from NLP technology.
Key Challenges Addressed by GlotLID-M
- Inaccurate Corpus Metadata: GlotLID-M addresses the problem of inaccurate or inadequate linguistic data for low-resource languages, ensuring accurate language identification.
- Leakage from High-Resource Languages: GlotLID-M prevents low-resource languages from being mistakenly associated with linguistic traits from high-resource languages.
- Difficulty Distinguishing Closely Related Languages: GlotLID-M accurately identifies dialects and closely related variants in low-resource languages.
- Macrolanguage vs. Varieties Handling: GlotLID-M effectively identifies dialects and other variations within macrolanguages.
- Handling Noisy Data: GlotLID-M performs well with noisy data, which is common in low-resource linguistic data.
According to evaluations, GlotLID-M outperforms four baseline LID models in terms of accuracy and false positive rate. It consistently recognizes languages accurately, even in challenging situations. GlotLID-M is designed with usability and efficiency in mind, making it easy to incorporate into pipelines for creating datasets.
Primary Contributions of GlotLID-M
- GlotLID-C Dataset: An extensive dataset encompassing 1665 languages, with a focus on low-resource languages across diverse domains.
- GlotLID-M Model: An open-source Language Identification model trained on the GlotLID-C dataset, capable of identifying languages among the 1665 languages in the dataset.
- Improved Performance: GlotLID-M demonstrates better performance compared to baseline models, achieving a notable improvement in F1 score on the Universal Declaration of Human Rights (UDHR) corpus.
