|
| ### Dataset Summary |
|
|
| The WikiText language modeling dataset is a collection of over 100 million tokens extracted from the set of verified |
| Good and Featured articles on Wikipedia. The dataset is available under the Creative Commons Attribution-ShareAlike License. |
|
|
| Compared to the preprocessed version of Penn Treebank (PTB), WikiText-2 is over 2 times larger and WikiText-103 is over |
| 110 times larger. The WikiText dataset also features a far larger vocabulary and retains the original case, punctuation |
| and numbers - all of which are removed in PTB. As it is composed of full articles, the dataset is well suited for models |
| that can take advantage of long term dependencies. |
|
|
| Each subset comes in two different variants: |
| - Raw (for character level work) contain the raw tokens, before the addition of the <unk> (unknown) tokens. |
| - Non-raw (for word level work) contain only the tokens in their vocabulary (wiki.train.tokens, wiki.valid.tokens, and wiki.test.tokens). |
| The out-of-vocabulary tokens have been replaced with the the <unk> token. |
|
