After completing all the cleaning and deduplication steps, our ultimate dataset comprises 6.3 trillion tokens spanning 167 languages. Table 1 provides an overview of the number of documents and tokens for the top 42 languages in CulturaX following each processing stage. As can be seen, our datacleaning pipeline can substantially reduce the number of documents in the original mC4 and OSCAR datasets for each language. The total number of removed documents accounts for 46.48% of our initial documents, suggesting the the effectiveness of our approaches to filter noisy information for multilingual datasets.
