The ultimate dataset contains 922 billion (B) HTML tokens, 106B PDF tokens, and 9B ArXiv tokens.
Sourcing Massive Portions of Multimodal Paperwork
HTML Pipeline
MINT-1T follows OBELICS’s methodology for extracting interleaved multimodal paperwork from CommonCrawl WARC information by parsing every WARC entry’s DOM tree. Whereas OBELICS solely processed paperwork from February 2020 to February 2023 CommonCrawl dumps, MINT-1T has expanded the doc pool to incorporate HTML paperwork from Might 2017 to April 2024 (with full dumps from October 2018 to April 2024 and partial dumps from earlier years). Just like OBELICS, MINT-1T filters out paperwork containing no photographs, greater than thirty photographs, or any photographs with URLs that embrace inappropriate substrings comparable to emblem, avatar, porn, and xxx.
PDF Pipeline
MINT-1T sources PDF paperwork from CommonCrawl WAT information from February 2023 to April 2024 dumps. Initially, all PDF hyperlinks are extracted from these dumps. MINT-1T then makes an attempt to obtain and skim PDFs utilizing PyMuPDF, discarding PDFs over 50MB (possible containing massive photographs) and people over 50 pages lengthy. Pages with out textual content are excluded, and a studying order is established for the remaining pages. Studying order is set by discovering the bounding field of all textual content blocks on a web page, clustering the blocks primarily based on columns, and ordering them from prime left to backside proper. Pictures are built-in into the sequence primarily based on their proximity to textual content blocks on the identical web page.
ArXiv Pipeline
MINT-1T builds ArXiv interleaved paperwork from LaTeX supply code utilizing TexSoup to search out determine tags and interleave photographs with the paper textual content. For multi-file papers, MINT-1T identifies the principle Tex file and replaces enter tags with the contents of its information. The LaTeX code is cleaned up by eradicating imports, bibliography, tables, and quotation tags. Since ArXiv is already a extremely curated knowledge supply, no further filtering and deduplication are carried out.
Textual content High quality Filtering
MINT-1T avoids utilizing model-based heuristics for textual content filtering, following practices established by RefinedWeb, Dolma, and FineWeb. Initially, non-English paperwork are eradicated utilizing Fasttext’s language identification mannequin (with a confidence threshold of 0.65). Paperwork with URLs containing NSFW substrings are additionally eliminated to exclude pornographic and undesirable content material. Textual content filtering strategies from RefinedWeb are utilized, particularly eradicating paperwork with extreme duplicate n-grams or these recognized as low high quality utilizing MassiveText guidelines.
Picture Filtering
After curating PDFs and HTML information, MINT-1T makes an attempt to obtain all picture URLs within the HTML dataset, discarding non-retrievable hyperlinks and eradicating paperwork with no legitimate picture hyperlinks. Pictures smaller than 150 pixels are discarded to keep away from noisy photographs comparable to logos and icons, and pictures bigger than 20,000 pixels are additionally eliminated as they normally correspond to off-topic photographs. For HTML paperwork, photographs with a facet ratio larger than two are eliminated to filter out low-quality photographs comparable to commercial banners. For PDFs, the brink is adjusted to 3 to protect scientific figures and tables.
The above determine represents how MINT-1T uniquely contains knowledge from PDFs and ArXiv paperwork past HTML sources.
Security Filtering
