A Dataset of Cryptic Crossword Clues

A Dataset of Cryptic Crossword Clues

cryptics.eigenfoo.xyz is a dataset of cryptic crossword1 clues, indicators and charades, collected from various blogs and publicly available digital archives.

The project scrapes several blogs and digital archives for cryptic crosswords. Out of these collected web pages, the clues, answers, clue numbers, blogger’s explanation and commentary, puzzle title and publication date are all parsed and extracted into a tabular dataset. The result is over half a million clues from cryptic crosswords over the past twelve years.

Two other datasets are subsequently derived from the clues - wordplay indicators and charades (a.k.a. substitutions). All told, the derived datasets contain over ten thousand wordplay indicators and over sixty thousand charades.

Currently the sources for clues are:

The data can be viewed online and downloaded for free (CSV, JSON, SQLite, advanced3). Detailed documentation can be found on the datasheet and the source code for creating the dataset is available on GitHub.
