### Dataset Summary |
|
|
|
This corpus is an attempt to recreate the dataset used for training XLM-R. This corpus comprises of monolingual data for 100+ languages and also includes data for romanized languages (indicated by *_rom). This was constructed using the urls and paragraph indices provided by the CC-Net repository by processing January-December 2018 Commoncrawl snapshots. |
|
|
|
### Supported Tasks and Leaderboards |
|
|
|
CC-100 is mainly inteded to pretrain language models and word represantations. |
|
|
|
### Languages |
|
|
|
To load a language which isn't part of the config, all you need to do is specify the language code in the config. |
|
You can find the valid languages in Homepage section of Dataset Description: https://data.statmt.org/cc-100/ |
|
E.g. |
|
|
|
`dataset = load_dataset("cc100", lang="en")` |
|
|
|
## Dataset Structure |
|
|
|
### Data Instances |
|
|
|
An example from the `am` configuration: |
|
|
|
``` |
|
{'id': '0', 'text': 'α°αααα α¨αα΅αα³ α ααα αα
α ααα³α
α·α α²-α αα α α₯α
αΌ ...\n'} |
|
``` |
|
|
|
Each data point is a paragraph of text. The paragraphs are presented in the original (unshuffled) order. Documents are separated by a data point consisting of a single newline character. |
|
|
|
### Data Fields |
|
|
|
The data fields are: |
|
|
|
- id: id of the example |
|
- text: content as a string |
|
|
|

### Personal and Sensitive Information |
|
|
|
Being constructed from Common Crawl, personal and sensitive information might be present. This **must** be considered before training deep learning models with CC-100, specially in the case of text-generation models. |
|
|

abstract = "This paper shows that pretraining multilingual language models at scale leads to significant performance gains for a wide range of cross-lingual transfer tasks. We train a Transformer-based masked language model on one hundred languages, using more than two terabytes of filtered CommonCrawl data. Our model, dubbed XLM-R, significantly outperforms multilingual BERT (mBERT) on a variety of cross-lingual benchmarks, including +14.6{\%} average accuracy on XNLI, +13{\%} average F1 score on MLQA, and +2.4{\%} F1 score on NER. XLM-R performs particularly well on low-resource languages, improving 15.7{\%} in XNLI accuracy for Swahili and 11.4{\%} for Urdu over previous XLM models. We also present a detailed empirical analysis of the key factors that are required to achieve these gains, including the trade-offs between (1) positive transfer and capacity dilution and (2) the performance of high and low resource languages at scale. Finally, we show, for the first time, the possibility of multilingual modeling without sacrificing per-language performance; XLM-R is very competitive with strong monolingual models on the GLUE and XNLI benchmarks. We will make our code and models publicly available.", |

The quality of these models benefits greatly from the size of the pretraining corpora as long as its quality is preserved. In this paper, we describe an automatic pipeline to extract massive high-quality monolingual datasets from Common Crawl for a variety of languages. Our pipeline follows the data processing introduced in fastText (Mikolov et al., 2017; Grave et al., 2018), that deduplicates documents and identifies their language. We augment this pipeline with a filtering step to select documents that are close to high quality corpora like Wikipedia.", |
