ClueWeb22, 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, ClueWeb22 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 to lower the barrier to entry. Many of these signals have been
widely used in industry but are available to the research community for the
first time at this scale.

ClueWeb22 是一个高质量的、大规模的 Web 语料库，旨在支持信息系统、检索 - 增强 AI 系统和模型预训练等领域的学术和工业研究。
