# IA-Original
IA-Original is a multilingual RoBERTa model pre-trained exclusively on 11 Indian languages from the Indo-Aryan language family. It is pre-trained on the monolingual corpora of these languages and subsequently evaluated on a set of diverse tasks.
The 11 languages covered by IA-Original are: Bhojpuri, Bengali, Gujarati, Hindi, Magahi, Marathi, Nepali, Oriya, Punjabi, Sanskrit, Urdu.
The code can be found [here](https://github.com/IBM/NL-FM-Toolkit). For more information, check-out our [paper](https://aclanthology.org/2021.emnlp-main.675/).
## Pretraining Corpus
We pre-trained IA-Original on the publicly available monolingual corpus. The corpus has the following distribution of languages:
| **Language** | **\# Sentences** | **\# Tokens** | |
| :------------ | ---------------: | ------------: | ------------: |
| | | **\# Total** | **\# Unique** |
| Hindi (hi) | 1552\.89 | 20,098\.73 | 25\.01 |
| Bengali (bn) | 353\.44 | 4,021\.30 | 6\.5 |
| Sanskrit (sa) | 165\.35 | 1,381\.04 | 11\.13 |
| Urdu (ur) | 153\.27 | 2,465\.48 | 4\.61 |
| Marathi (mr) | 132\.93 | 1,752\.43 | 4\.92 |
| Gujarati (gu) | 131\.22 | 1,565\.08 | 4\.73 |
| Nepali (ne) | 84\.21 | 1,139\.54 | 3\.43 |
| Punjabi (pa) | 68\.02 | 945\.68 | 2\.00 |
| Oriya (or) | 17\.88 | 274\.99 | 1\.10 |
| Bhojpuri (bh) | 10\.25 | 134\.37 | 1\.13 |
| Magahi (mag) | 0\.36 | 3\.47 | 0\.15 |
## Evaluation Results
IA-Original is evaluated on IndicGLUE and some additional tasks. For more details about the tasks, refer to the [paper](https://aclanthology.org/2021.emnlp-main.675/).
