### Dataset Summary

Current NLP datasets targeting ambiguity can be solved by a native speaker with relative ease. We present Cryptonite, a large-scale dataset based on cryptic crosswords, which is both linguistically complex and naturally sourced. Each example in Cryptonite is a cryptic clue, a short phrase or sentence with a misleading surface reading, whose solving requires disambiguating semantic, syntactic, and phonetic wordplays, as well as world knowledge. Cryptic clues pose a challenge even for experienced solvers, though top-tier experts can solve them with almost 100% accuracy. Cryptonite is a challenging task for current models; fine-tuning T5-Large on 470k cryptic clues achieves only 7.6% accuracy, on par with the accuracy of a rule-based clue solver (8.6%).

### Languages

English

## Dataset Structure

### Data Instances

This is one example from the train set.

```python
{
  'clue': 'make progress socially in stated region (5)',
  'answer': 'climb',
  'date': 971654400000,
  'enumeration': '(5)',
  'id': 'Times-31523-6across',
  'publisher': 'Times',
  'quick': False
}
```

### Data Fields

- `clue`: a string representing the clue provided for the crossword
- `answer`: a string representing the answer to the clue
- `enumeration`: a string representing the 
- `publisher`: a string representing the publisher of the crossword
- `date`: a int64 representing the UNIX timestamp of the date of publication of the crossword
- `quick`: a bool representing whether the crossword is quick (a crossword aimed at beginners, easier to solve)
- `id`: a string to uniquely identify a given example in the dataset

### Data Splits

Train (470,804 examples), validation (26,156 examples), test (26,157 examples).
