Wikipedia monolingual corpora

Here you can download text corpora extracted from the Wikipedia dumps in 30 languages, amounting to nearly 10 billion tokens altogether. Each XML file contains the full textual content of the individual language version of Wikipedia, extended with many annotations like article and paragraph boundaries, number of links referring to each article, crosslanguage links, categories and more. Have a quick look at a sample XML file containing one English article.

XML Format Description

The XML files contain the following information:

XML element mother element description
article wikipedia (XML root) This element encloses each Wikipedia article. It has an attribute name which contains the article’s title. The title is unique (in the current language version).
redirect article Articles that are redirects to another article are not stored in the XML files. However, the redirect information is contained in the redirect element(s) of the target article. The attribute name contains an article title that redirects to the present article. An article can have 0..n daughter elements of type redirect.
links_in article The attribute name contains the total number of textlinks in other articles that link to the current article.
textlink article The attribute name contains the anchor text that is used in a textlink to refer to the current article. The attribute freq contains the number of times this anchor text was used to refer to the current article.
category article The attribute name contains a Wikipedia category the current article is assigned to. An article can have 0..n daughter elements of type category.
links_out article The attribute name contains the number of textlinks in the current article that refer to other Wikipedia articles.
crosslanguage_link article The attribute name contains the title of a Wikipedia article in another language the current article is linked to. The attribute language specifies the target language.
Important note: In Wikipedia, crosslanguage links may link an article to a section of a target article. In this case, the link contains the article name followed by a ‚#‘ and the section’s anchor name. There are also crosslanguage links to other namespaces, e.g. categories or portals. These links contain a colon that separates the namespace from the link target.
disambiguation article This elements marks the article as a disambiguation page. It has no attributes.
content article This element encloses the current article’s textual content.
p content, h, math, table This element marks a paragraph boundary.
link content, h, math, table Marks a textlink to another Wikipedia article. The title of the target article is contained in the attribute target.
h content Marks a heading.
math content Marks a math formula.
table content Marks a table.
cell table Marks a table cell.

The sample contains one article from the English Wikipedia.

Extracting raw text from XML

You can extract text only from the XML files using the Perl script The usage is:

perl [Options] INPUT OUTPUT

where INPUT is an unzipped Wikipedia corpus XML file, and OUTPUT is the raw text file that will be produced. The encoding of the output file will be UTF-8.

Options: -articles The article mark-up is preserved (<article name=“…“>…</article>).
-p The paragraph mark-up is preserved (<p>…</p>).
-h The headings mark-up is preserved (<h>…</h>).
-nomath All content that is enclosed in math tags is deleted.
-notables All content that is enclosed in table tags is deleted.
-nodisambig Articles that are marked as disambiguation page are deleted.
-exclude-categories FILE All articles that belong to one of the categories listed in FILE are ignored. FILE has one category name per line. Some useful categories are given below.
-only-categories FILE Only articles are output that belong to one of the categories listed in FILE. FILE has one category name per line. Some useful categories are given below.

Useful categories

language description categories file
de people people_de.txt
en medicine medicine_en.txt

Known and unknown bugs

The corpora are based on the Wikipedia dumps which contain articles in Wiki markup format, packed in XML. Wiki markup uses all kinds of brackets to mark links, categories, etc. Because articles can be edited manually by anybody, unmatched brackets sometimes occur. In order to minimize noise in the corpus, we discard all articles with unmatched brackets, i.e. articles that can’t be parsed.

We also (try to) discard sections with weblinks and references at the end of articles, because they often contain foreign language material. (It’s not a bug, it’s a feature!)


Main purpose of the Wikipedia Monolingual Corpora is to provide large text corpora in many languages which can be used for the routine tasks of corpus linguistics, like generating word frequency lists or collecting n-gram statistics.

However, the rich annotations in the XML files facilitate many more applications:

  • categories allow to compile domain-specific corpora
  • compile multilingual document-aligned comparable corpora using the crosslanguage links
  • textlinks and redirects allow to collect expressions that are used to refer to a concept (i.e. a Wikipedia article)
  • The annotations cover all requirements to build ESA style semantic similarity resources.
