COCOA : A COrpus of Claims frOm NLP Articles

COCOA is corpus of sentences sourced from NLP papers and pre-prints published in English between 1952 and 2024. It contains additional annotations:

  • claim category labels reflecting the rhetorical function of sentences within papers (context, contribution, outline, result, impact, directions, limitation, non-claim); a part of these annotations was done manually, while the remainder labels were computed using a fine-tuned SciBERT model.
  • certainty annotations (sentence-level and aspect-level certainty) predicted using SciBERT models by Pei & Jurgens

Code related to the constitution, annotation and analysis of COCOA is available on GitHub.

This Huggingface dataset contains the data files of COCOA:

  • XML files of the papers included in COCOA
  • papers.csv: all the metadata about the papers included in COCOA
  • sentences-v1.csv: all the sentences of COCOA with annotations
  • sentences-v2.parquet: an updated version of sentences-v1.csv where some duplicates were removed
  • manual-sentences-v2.parquet: the subset of sentences from sentences-v2.parquet which were manually annotated

Parquet files should be loaded as follows:

import pandas as pd
import fastparquet

sentences = pd.read_parquet("sentences-v2.parquet", engine = "fastparquet")
