Dataset Card for Text-based NP Enrichment

Dataset Summary

Text-based NP Enrichment (TNE) is a natural language understanding (NLU) task, which focus on relations between noun phrases (NPs) that can be mediated via prepositions. The dataset contains 5,497 documents, annotated exhaustively with all possible links between the NPs in each document.

The main data comes from WikiNews, which is used for train/dev/test. We also collected an additional set of 509 documents to serve as out of distribution (OOD) data points, from the Book Corpus, IMDB reviews and Reddit.

Supported Tasks and Leaderboards

The data contain both the main data for the TNE task, as well as coreference resolution data. There are two leaderboards for the TNE data, one for the standard test set, and another one for the OOD test set:

• TNE Leaderboard
• TNE OOD Leaderboard

Languages

The text in the dataset is in English, as spoken in the different domains we include. The associated BCP-47 code is en.

Dataset Structure

Data Instances

The original files are in a jsonl format, containing a dictionary of a single document, in each line. Each document contain a different amount of labels, due to the different amount of NPs. The test and ood splits come without the annotated labels.

Data Fields

A document consists of:

• id: a unique identifier of a document, beginning with r and followed by a number
• text: the text of the document. The title and subtitles (if exists) are separated with two new lines. The paragraphs are separated by a single new line.
• tokens: a list of string, containing the tokenized tokens
• nps: a list of dictionaries, containing the following entries:
  • text: the text of the np
  • start_index: an integer indicating the starting index in the text
  • end_index: an integer indicating the ending index in the text
  • start_token: an integer indicating the first token of the np out of the tokenized tokens
  • end_token: an integer indicating the last token of the np out of the tokenized tokens
  • id: the id of the np
• np_relations: these are the relation labels of the document. It is a list of dictionaries, where each dictionary contains:
  • anchor: the id of the anchor np
  • complement: the id of the complement np
  • preposition: the preposition that links between the anchor and the complement. This can take one out of 24 pre-defined preposition (23 + member(s)-of)
  • complement_coref_cluster_id: the coreference id, which the complement is part of.
• coref: the coreference labels. It contains a list of dictionaries, where each dictionary contains:
  • id: the id of the coreference cluster
  • members: the ids of the nps members of such cluster
  • np_type: the type of cluster. It can be either
    • standard: regular coreference cluster
    • time/date/measurement: a time / date / measurement np. These will be singletons.
    • idiomatic: an idiomatic expression
• metadata: metadata of the document. It contains the following:
  • annotators: a dictionary with anonymized annotators id
    • coref_worker: the coreference worker id
    • consolidator_worker: the consolidator worker id
    • np-relations_worker: the np relations worker id
  • url: the url where the document was taken from (not always existing)
  • source: the original file name where the document was taken from

Data Splits

The dataset is spread across four files, for the four different splits: train, dev, test and test_ood. Additional details on the data statistics can be found in the paper

Dataset Creation

Curation Rationale

TNE was build as a new task for language understanding, focusing on extracting relations between nouns, moderated by prepositions.
