On May 24, CDT gathered experts from various countries to discuss the challenges and opportunities of developing language models that can work across different languages. The event marked the release of their latest report titled “Lost in Translation: Large Language Models in Non-English Content Analysis.” This report explores the capabilities and limitations of multilingual language models, which use machine learning to establish connections between different languages and bring the power of language models to languages with limited digitized text.
While multilingual language models have shown impressive results in tasks like grammar correction and sentence translation, they face limitations in contextual understanding and language-specific tasks such as content moderation. Companies like Meta, Google, and Bumble have already started implementing these models for detecting and taking action against abusive speech.
The discussion at the event highlighted the issue of the resourcedness gap, which refers to the disparity in high-quality training datasets available in English compared to other languages. This gap makes it challenging to develop language AI systems in languages other than English and reinforces the dominance of the English language in the field of natural language processing. As a result, models trained on high-quality English text tend to perform poorly in languages other than English.
The resourcedness gap has significant consequences. Without adequate training data, language models may lack knowledge and understanding of certain topics, perpetuating the misconception that these concepts do not exist in certain cultures or languages. This poses a threat to the diversity of languages and cultures worldwide.
Digitizing text in languages with limited resources can help address some of the shortcomings of language models but is not a perfect solution. Creating a singular multilingual model that works across multiple languages is not straightforward due to the curse of multilinguality. Language models have limited capacity, and prioritizing one language may result in reduced performance in non-prioritized languages.
To overcome these challenges, it is essential to invest in diverse tools and technical architectures. Relying solely on multilingual models may not be the most effective approach, especially for languages with limited resources. Traditional rule-based systems and classifiers can be more suitable for languages with few examples of text or specific contexts.
Increased transparency in the development and deployment of language models is also crucial. Currently, there is a gap between research conducted by academia and tech companies and the practical implementation of these models. Bridging this gap can lead to better understanding and utilization of language models.
In conclusion, the development of language models that can effectively work across different languages requires addressing the resourcedness gap, exploring diverse technical architectures, and promoting transparency in the field. By doing so, we can ensure that language models benefit all language speakers and contribute to the preservation and growth of diverse languages and cultures.
Editor’s Notes:
Language models have the potential to revolutionize the way we communicate and interact with technology. However, it’s crucial to consider the challenges and limitations associated with these models, especially in non-English languages. The resourcedness gap presents a significant obstacle, hindering the development of language AI systems in languages other than English. This not only perpetuates the dominance of English in the information environment but also leads to inaccurate and ineffective language models in non-English languages.
Investing in diverse tools and technical architectures is necessary to overcome these challenges. A multilingual model alone cannot address the complex dynamics of different languages. Rule-based systems and classifiers can provide more targeted solutions for languages with limited resources or specific contexts. Moreover, transparency plays a vital role in ensuring the responsible development and deployment of language models. We need clearer insights into how these models are being developed and used to make informed decisions.
CDT’s report sheds light on these pressing issues and calls for action. By actively working towards bridging the resourcedness gap, exploring alternative technical approaches, and increasing transparency, we can create language models that truly cater to the needs and nuances of diverse languages. This will not only enhance user experiences but also promote linguistic and cultural diversity on a global scale.
