Dataset Structure

Data Instances

A typical data point represents a paragraph in a Wikipedia article.

The paragraph_text field contains the original text in an NFC normalized, UTF-8 encoded string.

The paragraph_anchors field contains a list of anchors, each represented by a struct with the inclusive starting UTF-8 code point start field, exclusive ending UTF-8 code point end field, a nullable qid field, a nullable pageid field, and an NFC normalized, UTF-8 encoded title (Wikipedia) field.

Additionally, each paragraph has article_title, article_pageid, and (nullable) article_qid fields referring to the article the paragraph came from.

There is also a nullable, NFC normalized, UTF-8 encoded section_heading field, and an integer section_level field referring to the heading (if it exists) of the article section, and the level in the section hierarchy that the paragraph came from.

The qid fields refers to Wikidata's QID identifiers, while the pageid and title fields refer to Wikipedia's pageID and title identifiers (there is a one-to-one mapping between pageIDs and titles).

NOTE: An anchor will always have a title, but that doesn't mean it has to have a pageid. This is because Wikipedia allows defining anchors to nonexistent articles.

An example from the WikiAnc EN test set looks as follows:

{
  "uuid": "5f74e678-944f-4761-a5e0-b6426f6f61b8",
  "article_title": "Climatius",
  "article_pageid": 5394373,
  "article_qid": 867987,
  "section_heading": null,
  "section_level": 0,
  "paragraph_text": "It was a small fish, at 7.5 cm, and to discourage predators, Climatius sported fifteen sharp spines. There was one spine each on the paired pelvic and pectoral fins, and on the aingle anal and two dorsal fins, and a four pairs without fins on the fish's underside.",
  "paragraph_anchors": [
    {
      "start": 140,
      "end": 146,
      "qid": 3335089,
      "pageid": 56849833,
      "title": "Pelvic_fin"
    },
    {
      "start": 151,
      "end": 159,
      "qid": 4162555,
      "pageid": 331956,
      "title": "Pectoral_fin"
    },
    {
      "start": 184,
      "end": 188,
      "qid": 4162555,
      "pageid": 331958,
      "title": "Anal_fin"
    },
    {
      "start": 197,
      "end": 208,
      "qid": 1568355,
      "pageid": 294244,
      "title": "Dorsal_fin"
    }
  ]
}

Data Fields

• uuid: a UTF-8 encoded string representing a v4 UUID that uniquely identifies the example
• article_title: an NFC normalized, UTF-8 encoded Wikipedia title of the article; spaces are replaced with underscores
• article_pageid: an integer representing the Wikipedia pageID of the article
• article_qid: an integer representing the Wikidata QID this article refers to; it can be null if the entity didn't exist in Wikidata at the time of the creation of the original dataset
• section_heading: a nullable, NFC normalized, UTF-8 encoded string representing the section heading
• section_level: an integer representing the level of the section in the section hierarchy
• paragraph_text: an NFC normalized, UTF-8 encoded string representing the paragraph
• paragraph_anchors: a list of structs representing anchors, each anchor has:
  • start: an integer representing the inclusive starting UTF-8 code point of the anchors
  • end: an integer representing the exclusive ending UTF-8 code point of the anchor
  • qid: a nullable integer representing the Wikidata QID this anchor refers to; it can be null if the entity didn't exist in Wikidata at the time of the creation of the original dataset
  • pageid: a nullable integer representing the Wikipedia pageID of the anchor; it can be null if the article didn't exist in Wikipedia at the time of the creation of the original dataset
  • title: an NFC normalized, UTF-8 encoded string representing the Wikipedia title of the anchor; spaces are replaced with underscores; can refer to a nonexistent Wikipedia article

Data Splits

The data is split into training, validation and test sets; paragraphs belonging to the same article aren't necessarily in the same split. The final split sizes are as follows:

	Train	Validation	Test
WikiAnc EN - articles	5,883,342	2,374,055	2,375,830
WikiAnc EN - paragraphs	34,555,183	4,317,326	4,321,613
WikiAnc EN - anchors	87,060,158	10,876,572	10,883,232
WikiAnc EN - anchors with QIDs	85,414,610	10,671,262	10,677,412
WikiAnc EN - anchors with pageIDs	85,421,513	10,672,138	10,678,262

NOTE: The number of articles in the table above refers to the number of articles that have at least one paragraph belonging to the article appear in the split.
