Workshop @ EMNLP 2026 · Budapest, Hungary · 29 October 2026
The 13th edition of the Web-as-Corpus (WaC-13) workshop will be co-located with EMNLP 2026 in Budapest, Hungary. The workshop is endorsed by the SIGWAC ACL Special Interest Group in Web-as-Corpus, the Common Crawl Foundation, and the OpenEuroLLM project.
The World Wide Web has evolved from a resource for building linguistic corpora into the central data infrastructure powering modern natural language processing and Large Language Models (LLMs). As web-scale data increasingly shapes AI systems' knowledge and capabilities, understanding its quality, representativeness, and ethical implications has become critical.
At the same time, the "more is better" paradigm is being challenged by issues such as machine-generated content, data toxicity, limited metadata, and the under-representation of many languages and domains. These challenges call for a shift toward Data-Centric AI, focusing on the curation, analysis, and responsible use of web-derived data.
WaC-13 provides a multidisciplinary forum for research addressing the full lifecycle of web data. We invite submissions on methods, resources, and applications related to web corpora, with special emphasis on multilingual data and less-resourced languages.
Submissions are invited on (but not limited to):

Note: All deadlines are 11:59PM "Anywhere on Earth", and are displayed above in your local time zone for convenience. Depending on your time zone, the displayed date may be one day later than the official deadline date.
We invite short (4 pages) and long (8 pages) papers. We allow for archival (to appear in the ACL Anthology) and non-archival submissions. Submissions should follow the ARR submission requirements. Following the ACL and ARR policies, there is no anonymity period requirement.
Paper submissions must use the official ACL style template. Please follow the paper formatting guidelines general to “*ACL” conferences. Authors may not modify these style files or use template designed for other conferences. The LaTeX style files are also available as an Overleaf template.
Submissions will be possible through ARR commitment and through direct submission via openreview.net
