PGN Dataset
Last Updated: 2025-01-26
Description
This is a dataset of chess games in Portable Game Notation (PGN) format. The dataset was created by cleaning and formatting the milesh1/35-million-chess-games dataset from Kaggle.
This version of the pgn-dataset does not include the [g_start] and [g_end] special tokens that PGNTokenizer uses to denote the start and end of a game. The pgn-dataset-including-special-tokens dataset includes these tokens.
Notes
This was the training dataset for PGNTokenizer. For more information about using PGNTokenizer visit the GitHub repository.
