JFLEG (JHU FLuency-Extended GUG) is an English grammatical error correction (GEC) corpus. It is a gold standard benchmark for developing and evaluating GEC systems with respect to fluency (extent to which a text is native-sounding) as well as grammaticality. For each source document, there are four human-written corrections.

Supported Tasks and Leaderboards

Grammatical error correction.

Languages

English (native as well as L2 writers)

Dataset Structure

Data Instances

Each instance contains a source sentence and four corrections. For example:

{
  'sentence': "They are moved by solar energy ."
  'corrections': [
    "They are moving by solar energy .",
    "They are moved by solar energy .",
    "They are moved by solar energy .",
    "They are propelled by solar energy ." 
  ]
}

Data Fields

sentence: original sentence written by an English learner
corrections: corrected versions by human annotators. The order of the annotations are consistent (eg first sentence will always be written by annotator "ref0").

Data Splits

This dataset contains 1511 examples in total and comprise a dev and test split.
There are 754 and 747 source sentences for dev and test, respectively.
Each sentence has 4 corresponding corrected versions.
