{"url":"/dataset/clueweb22","name":"ClueWeb22","full_name":null,"description_markdown":"**ClueWeb22** is the newest iteration of the ClueWeb line of datasets, provides 10 billion web pages affiliated with rich information. Its design was influenced by the need for a high quality, large scale web corpus to support a range of academic and industry research, for example, in information systems, retrieval-augmented AI systems, and model pretraining. Compared with earlier CLUEWeb corpora, the ClUEWeb22 corpus is larger, more varied, of higher-quality, and aligned with the document distributions in commercial web search. Besides raw HTML, the dataset includes rich information about the web pages provided by industry-standard document understanding systems, including the visual representation of pages rendered by a web browser, parsed HTML structure information from a neural network parser, and pre-processed cleaned document text.\r\n\r\nSource: [https://arxiv.org/pdf/2211.15848v1.pdf](https://arxiv.org/pdf/2211.15848v1.pdf)\r\n\r\nImage Source: [ClueWeb22: 10 Billion Web Documents with Rich Information](https://arxiv.org/pdf/2211.15848v1.pdf)","description_withheld":null,"homepage":"https://lemurproject.org/clueweb22/","introduced_date":"2022-11-29","introduced_date_note":null,"introduced_by":{"paper":"/paper/clueweb22-10-billion-web-documents-with-rich","title":"ClueWeb22: 10 Billion Web Documents with Visual and Semantic Information","first_author":"Arnold Overwijk","url":null},"license":null,"modalities":[{"name":"Images","url":"/datasets/modality/images"},{"name":"Texts","url":"/datasets/modality/texts"}],"tasks":[{"name":"Information Retrieval","url":"/task/information-retrieval","datasets_with_task":"/datasets/task/information-retrieval"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["ClueWeb22"],"data_loaders":[],"num_papers_in_archive":9,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
