The field of artificial intelligence (AI) is advancing at a breakneck pace. From voice assistants to self-driving cars, are becoming integrated into more aspects of our lives. However, much of this progress has centered on the English language. AI systems still struggle when dealing with other languages spoken by billions of people worldwide. But a groundbreaking new dataset called aims to change all that. AI systems CulturaX In this in-depth look, we’ll cover how CulturaX could democratize AI and spread its benefits to diverse communities across the planet. The Limitations of AI Today Many of today’s most systems are powered by neural networks trained on massive datasets. But for most languages beyond English, publicly available training data has been scarce. This has led to a couple of major limitations:’ advanced AI First, AI systems tend to work much worse in other languages. Translation tools like Google Translate used to be notoriously error-prone outside of English. Voice assistants struggle with accurate speech recognition and natural responses in foreign tongues. Even fundamental tasks like identifying the language of a text snippet are less reliable. Second, lack of data stifles progress in improving AI systems for non-English languages. With limited data to train on, fewer researchers bother focusing on these languages. English ends up dominating research. This creates a vicious cycle where other languages get left further and further behind. Driving Democratization Through Data To democratize access to quality training data, researchers at the University of Oregon and Adobe Research have constructed a game-changing resource called CulturaX ( ). This dataset provides: paper here Text data for a whopping 167 languages Over 6 trillion words in total Extensive cleaning and deduplication Completely free and open availability With quality data now available for so many more languages, researchers worldwide can develop better AI systems for their own communities. No longer limited by lack of training data, progress in languages beyond English may accelerate rapidly. The open nature of CulturaX also allows any issues around bias and fairness for specific languages to be identified and addressed. With more equal access to data, the democratization and benefits of AI can be shared across diverse linguistic groups. Merging Two Massive Multilingual Datasets To construct CulturaX, the researchers combined two existing large-scale multilingual datasets - mC4 and OSCAR. Together, these provided an initial 13.5 billion documents in over 100 languages. While a great starting point, these datasets had some limitations. mC4 used a weaker language identification tool, introducing errors. Neither dataset was comprehensively deduplicated at the document level. The text also included untranslated snippets and other noise. Cleaning up and merging such a vast corpus of text required ingenious methods. Let's look at how the researchers transformed these raw datasets into a quality resource. Refining a Truly Massive Amount of Text To produce the CulturaX dataset, the raw content from mC4 and OSCAR underwent extensive processing. The key steps included: Identifying Languages Accurately Replaced mC4's language detector with FastText - the current state-of-the-art Removed mC4 docs without confident language ID Ensured all 167 languages are fully supported Filtering Out Harmful Content Used blacklist to remove toxic websites Eliminated documents with abuse, porn, hate speech, etc. Catching Noisy Documents Computed metrics like repetition to find low-quality docs Filtered out statistical outliers for each language Cleaning Individual Documents Stripped irrelevant content like code snippets Normalized formatting across documents Deduplicating Similar Entries Used MinHash for near-deduplication across languages Compared document URLs to remove duplicates Through each stage, the goal was to prune away low-quality, repetitive, and potentially harmful content. This leaves a refined dataset optimized for training AI systems. CulturaX by the Numbers The final CulturaX corpus contains: - From Afrikaans to Zulu, encompassing global diversity 167 languages - Orders of magnitude more than previous multilingual datasets 6.3 trillion words - Providing a huge variety of text sources 15 billion documents - Requiring new methods to process efficiently 27 terabytes of text This makes CulturaX the largest and most diverse multilingual dataset openly available today. The scale finally begins approaching that of private datasets used by tech giants. Multilingual AI's Potential With CulturaX now available for researchers worldwide, what could be achieved through its use? Some possibilities include: - to accurately translate text, audio, and video between virtually any language pair with a single model Training universal translation models - that can converse naturally in hundreds of languages and with local knowledge Building culturally-aware chatbots - able to understand and respond fluently across languages and accents Developing truly global voice assistants - so that web content of all types can be precisely understood and retrieved Enabling nuanced multilingual search - like improved speech recognition for tonal languages such as Mandarin Chinese Advancing language-specific assets Of course, models will need to be carefully developed and tested to avoid issues like bias amplification. But the possibilities are endless! Next Steps to Spread Benefits Broadly Releasing CulturaX removes a major obstacle to equal access to the benefits of AI globally. However, many challenges remain to develop and apply this technology thoughtfully. The next steps could include: - in identifying potential harms from AI systems built using their languages and data. Involving under-resourced communities - for languages with limited text data, creative solutions can help generate training data. Filling remaining data gaps - using images, videos, and speech data alongside text may improve versatility. Exploring multimodal learning - across languages, cultures, demographics, and tasks before deployment. Testing rigorously for biases - so insights from global researchers continuously improve shared models and data. Investing in two-way open research Through collaborative efforts guided by inclusiveness, AI's remarkable potential can be shared broadly. The CulturaX dataset opens the door to that future for all languages. Conclusion With its unprecedented linguistic breadth and meticulous construction, CulturaX represents a historic advance for . This post has only scratched the surface of the countless possibilities now opened up by democratizing access to quality training data across the world's languages and cultures. It's time to imagine - then build - an AI future enriched by humanity in all its diversity. multilingual AI Also published . here
