Dataset Card for WikiAuto

Dataset Summary

WikiAuto provides a set of aligned sentences from English Wikipedia and Simple English Wikipedia as a resource to train sentence simplification systems.

The authors first crowd-sourced a set of manual alignments between sentences in a subset of the Simple English Wikipedia and their corresponding versions in English Wikipedia (this corresponds to the manual config in this version of dataset), then trained a neural CRF system to predict these alignments.

The trained alignment prediction model was then applied to the other articles in Simple English Wikipedia with an English counterpart to create a larger corpus of aligned sentences (corresponding to the auto, auto_acl, auto_full_no_split, and auto_full_with_split configs here).

Supported Tasks and Leaderboards

The dataset was created to support a text-simplification task. Success in these tasks is typically measured using the SARI and FKBLEU metrics described in the paper Optimizing Statistical Machine Translation for Text Simplification.

Languages

While both the input and output of the proposed task are in English (en), it should be noted that it is presented as a translation task where Wikipedia Simple English is treated as its own idiom. For a statement of what is intended (but not always observed) to constitute Simple English on this platform, see Simple English in Wikipedia.

Dataset Structure

Data Instances

The data in all of the configurations looks a little different.

A manual config instance consists of a sentence from the Simple English Wikipedia article, one from the linked English Wikipedia article, IDs for each of them, and a label indicating whether they are aligned. Sentences on either side can be repeated so that the aligned sentences are in the same instances. For example:

{'alignment_label': 1,
 'normal_sentence_id': '0_66252-1-0-0',
 'simple_sentence_id': '0_66252-0-0-0',
 'normal_sentence': 'The Local Government Act 1985 is an Act of Parliament in the United Kingdom.', 'simple_sentence': 'The Local Government Act 1985 was an Act of Parliament in the United Kingdom', 'gleu_score': 0.800000011920929}

Is followed by

{'alignment_label': 0,
 'normal_sentence_id': '0_66252-1-0-1',
 'simple_sentence_id': '0_66252-0-0-0',
 'normal_sentence': 'Its main effect was to abolish the six county councils of the metropolitan counties that had been set up in 1974, 11 years earlier, by the Local Government Act 1972, along with the Greater London Council that had been established in 1965.',
 'simple_sentence': 'The Local Government Act 1985 was an Act of Parliament in the United Kingdom', 'gleu_score': 0.08641975373029709}

The auto config shows a pair of an English and corresponding Simple English Wikipedia as an instance, with an alignment at the paragraph and sentence level:

{'example_id': '0',
 'normal': {'normal_article_content': {'normal_sentence': ["Lata Mondal ( ; born: 16 January 1993, Dhaka) is a Bangladeshi cricketer who plays for the Bangladesh national women's cricket team.",
    'She is a right handed batter.',
    'Mondal was born on January 16, 1993 in Dhaka, Bangladesh.',
    "Mondal made her ODI career against the Ireland women's cricket team on November 26, 2011.",
    "Mondal made her T20I career against the Ireland women's cricket team on August 28, 2012.",
    "In October 2018, she was named in Bangladesh's squad for the 2018 ICC Women's World Twenty20 tournament in the West Indies.",
    "Mondal was a member of the team that won a silver medal in cricket against the China national women's cricket team at the 2010 Asian Games in Guangzhou, China."],
   'normal_sentence_id': ['normal-41918715-0-0',
    'normal-41918715-0-1',
    'normal-41918715-1-0',
    'normal-41918715-2-0',
    'normal-41918715-3-0',
    'normal-41918715-3-1',
    'normal-41918715-4-0']},
  'normal_article_id': 41918715,
  'normal_article_title': 'Lata Mondal',
  'normal_article_url': 'https://en.wikipedia.org/wiki?curid=41918715'},
 'paragraph_alignment': {'normal_paragraph_id': ['normal-41918715-0'],
  'simple_paragraph_id': ['simple-702227-0']},
 'sentence_alignment': {'normal_sentence_id': ['normal-41918715-0-0',
   'normal-41918715-0-1'],
  'simple_sentence_id': ['simple-702227-0-0', 'simple-702227-0-1']},
 'simple': {'simple_article_content': {'simple_sentence': ["Lata Mondal (born: 16 January 1993) is a Bangladeshi cricketer who plays for the Bangladesh national women's cricket team.",
    'She is a right handed bat.'],
   'simple_sentence_id': ['simple-702227-0-0', 'simple-702227-0-1']},
  'simple_article_id': 702227,
  'simple_article_title': 'Lata Mondal',
  'simple_article_url': 'https://simple.wikipedia.org/wiki?curid=702227'}}

Finally, the auto_acl, the auto_full_no_split, and the auto_full_with_split configs were obtained by selecting the aligned pairs of sentences from auto to provide a ready-to-go aligned dataset to train a sequence-to-sequence system. While auto_acl corresponds to the filtered version of the data used to train the systems in the paper, auto_full_no_split and auto_full_with_split correspond to the unfiltered versions with and without sentence splits respectively. In the auto_full_with_split config, we join the sentences in the simple article mapped to the same sentence in the complex article to capture sentence splitting. Split sentences are separated by a <SEP> token. In the auto_full_no_split config, we do not join the splits and treat them as separate pairs. An instance is a single pair of sentences:

{'normal_sentence': 'In early work , Rutherford discovered the concept of radioactive half-life , the radioactive element radon , and differentiated and named alpha and beta radiation .\n',
 'simple_sentence': 'Rutherford discovered the radioactive half-life , and the three parts of radiation which he named Alpha , Beta , and Gamma .\n'}

Data Fields

The data has the following field:

  • normal_sentence: a sentence from English Wikipedia.
  • normal_sentence_id: a unique ID for each English Wikipedia sentence. The last two dash-separated numbers correspond to the paragraph number in the article and the sentence number in the paragraph.
  • simple_sentence: a sentence from Simple English Wikipedia.
  • simple_sentence_id: a unique ID for each Simple English Wikipedia sentence. The last two dash-separated numbers correspond to the paragraph number in the article and the sentence number in the paragraph.
  • alignment_label: signifies whether a pair of sentences is aligned: labels are 2:partialAligned, 1:aligned and 0:notAligned
  • paragraph_alignment: a first step of alignment mapping English and Simple English paragraphs from linked articles
  • sentence_alignment: the full alignment mapping English and Simple English sentences from linked articles
  • gleu_score: the sentence level GLEU (Google-BLEU) score for each pair.

Data Splits

In auto, the part_2 split corresponds to the articles used in manual, and part_1 has the rest of Wikipedia.

The manual config is provided with a train/dev/test split with the following amounts of data:

train validation test
Total sentence pairs 373801 73249 118074
Aligned sentence pairs 1889 346 677

Dataset Creation

Curation Rationale

Simple English Wikipedia provides a ready source of training data for text simplification systems, as 1. articles in different languages are linked, making it easier to find parallel data and 2. the Simple English data is written by users for users rather than by professional translators. However, even though articles are aligned, finding a good sentence-level alignment can remain challenging. This work aims to provide a solution for this problem. By manually annotating a sub-set of the articles, they manage to achieve an F1 score of over 88% on predicting alignment, which allows to create a good quality sentence level aligned corpus using all of Simple English Wikipedia.

Source Data

Initial Data Collection and Normalization

The authors mention that they "extracted 138,095 article pairs from the 2019/09 Wikipedia dump [...] using an improved version of the WikiExtractor library". The SpaCy library is used for sentence splitting.

Who are the source language producers?

The dataset uses langauge from Wikipedia: some demographic information is provided here.

Annotations

Annotation process

Sentence alignment labels were obtained for 500 randomly sampled document pairs (10,123 sentence pairs total). The authors pre-selected several alignment candidates from English Wikipedia for each Simple Wikipedia sentence based on various similarity metrics, then asked the crowd-workers to annotate these pairs.

Who are the annotators?

No demographic annotation is provided for the crowd workers. [More Information Needed]
