The Wikipedia Text Reuse Corpus 2018 (Webis-Wikipedia-Text-Reuse-18) containing text reuse cases extracted from within Wikipedia and in between Wikipedia and a sample of the Common Crawl. The corpus has following structure: wikipedia.jsonl.bz2: Each line, representing a Wikipedia article, contains a json array of article_id, article_title, and article_body within-wikipedia-tr-01.jsonl.bz2: Each line, representing a text reuse case, contains a json array of s_id (source article id), t_id (target article id), s_text (source text), t_text (target text) within-wikipedia-tr-02.jsonl.bz2: Each line, representing a text reuse case, contains a json array of s_id (source article id), t_id (target article id), s_text (source text), t_text (target text) preprocessed-web-sample.jsonl.xz: Each line, representing a web page, contains a json object of d_id, d_url, and content without-wikipedia-tr.jsonl.bz2: Each line, representing a text reuse case, contains a json array of s_id (Wikipedia article id), d_id (web page id), s_text (article text), d_content (web page content) The datasets were extracted in the work by Alshomary et al. 2018 that aimed to study the text reuse phenomena related to Wikipedia at scale. A pipeline for large scale text reuse extraction was developed and used on Wikipedia and the CommonCrawl. {"references": ["Milad Alshomary, Michael V\u00f6lske, Tristan Licht, Henning Wachsmuth, Benno Stein, Matthias Hagen, and Martin Potthast.
