Dataset Card for WebNLG

Dataset Summary

The WebNLG challenge consists in mapping data to text. The training data consists of Data/Text pairs where the data is a set of triples extracted from DBpedia and the text is a verbalisation of these triples. For instance, given the 3 DBpedia triples shown in (a), the aim is to generate a text such as (b). It is a valuable resource and benchmark for the Natural Language Generation (NLG) community. However, as other NLG benchmarks, it only consists of a collection of parallel raw representations and their corresponding textual realizations. This work aimed to provide intermediate representations of the data for the development and evaluation of popular tasks in the NLG pipeline architecture, such as Discourse Ordering, Lexicalization, Aggregation and Referring Expression Generation.

Supported Tasks and Leaderboards

The dataset supports a other-structured-to-text task which requires a model takes a set of RDF (Resource Description Format) triples from a database (DBpedia) of the form (subject, property, object) as input and write out a natural language sentence expressing the information contained in the triples.

Languages

The dataset is presented in two versions: English (config en) and German (config de)

Dataset Structure

Data Instances

A typical example contains the original RDF triples in the set, a modified version which presented to crowd workers, and a set of possible verbalizations for this set of triples:

{ 'category': 'Politician',
 'eid': 'Id10',
 'lex': {'comment': ['good', 'good', 'good'],
         'lid': ['Id1', 'Id2', 'Id3'],
         'text': ['World War II had Chiang Kai-shek as a commander and United States Army soldier Abner W. Sibal.',
                  'Abner W. Sibal served in the United States Army during the Second World War and during that war Chiang Kai-shek was one of the commanders.',
                  'Abner W. Sibal, served in the United States Army and fought in World War II, one of the commanders of which, was Chiang Kai-shek.']},
 'modified_triple_sets': {'mtriple_set': [['Abner_W._Sibal | battle | World_War_II',
                                           'World_War_II | commander | Chiang_Kai-shek',
                                           'Abner_W._Sibal | militaryBranch | United_States_Army']]},
 'original_triple_sets': {'otriple_set': [['Abner_W._Sibal | battles | World_War_II', 'World_War_II | commander | Chiang_Kai-shek', 'Abner_W._Sibal | branch | United_States_Army'],
                                          ['Abner_W._Sibal | militaryBranch | United_States_Army',
                                           'Abner_W._Sibal | battles | World_War_II',
                                           'World_War_II | commander | Chiang_Kai-shek']]},
 'shape': '(X (X) (X (X)))',
 'shape_type': 'mixed',
 'size': 3}

Data Fields

The following fields can be found in the instances:

  • category: the category of the DBpedia entites present in the RDF triples.
  • eid: an example ID, only unique per split per category.
  • size: number of RDF triples in the set.
  • shape: (for v3 only) Each set of RDF-triples is a tree, which is characterised by its shape and shape type. shape is a string representation of the tree with nested parentheses where X is a node ( see Newick tree format)
  • shape_type: (for v3 only) is a type of the tree shape, which can be: chain (the object of one triple is the subject of the other); sibling (triples with a shared subject); mixed (both chain and sibling types present).
  • 2017_test_category: (for webnlg_challenge_2017) tells whether the set of RDF triples was present in the training set or not.
  • lex: the lexicalizations, with:
    • text: the text to be predicted.
    • lid: a lexicalizayion ID, unique per example.
    • comment: the lexicalizations were rated by crowd workers are either good or bad

Data Splits

The en version has train, test and dev splits; the de version, only train and dev.

Dataset Creation

Curation Rationale

Natural Language Generation (NLG) is the process of automatically converting non-linguistic data into a linguistic output format (Reiter andDale, 2000; Gatt and Krahmer, 2018). Recently, the field has seen an increase in the number of available focused data resources as E2E (Novikova et al., 2017), ROTOWIRE(Wise-man et al., 2017) and WebNLG (Gardent et al.,2017a,b) corpora. Although theses recent releases are highly valuable resources for the NLG community in general,nall of them were designed to work with end-to-end NLG models. Hence, they consist of a collection of parallel raw representations and their corresponding textual realizations. No intermediate representations are available so researchersncan straight-forwardly use them to develop or evaluate popular tasks in NLG pipelines (Reiter and Dale, 2000), such as Discourse Ordering, Lexicalization, Aggregation, Referring Expression Generation, among others. Moreover, these new corpora, like many other resources in Computational Linguistics more in general, are only available in English, limiting the development of NLG-applications to other languages.
