### InCaseLawBERT |
|
Model and tokenizer files for the InLegalBERT model. |
|
|
|
### Training Data |
|
For building the pre-training corpus of Indian legal text, we collected a large corpus of case documents from the Indian Supreme Court and many High Courts of India. |
|
These documents were collected from diverse publicly available sources on the Web, such as official websites of these courts (e.g., [the website of the Indian Supreme Court](https://main.sci.gov.in/)), the erstwhile website of the Legal Information Institute of India, |
|
the popular legal repository [IndianKanoon](https://www.indiankanoon.org), and so on. |
|
The court cases in our dataset range from 1950 to 2019, and belong to all legal domains, such as Civil, Criminal, Constitutional, and so on. |
|
Additionally, we collected 1,113 Central Government Acts, which are the documents codifying the laws of the country. Each Act is a collection of related laws, called Sections. These 1,113 Acts contain a total of 32,021 Sections. |
|
In total, our dataset contains around 5.4 million Indian legal documents (all in the English language). |
|
The raw text corpus size is around 27 GB. |
|
|
|
### Training Objective |
|
This model is initialized with the [Legal-BERT model](https://huggingface.co/zlucia/legalbert) from the paper [When does pretraining help?: assessing self-supervised learning for law and the CaseHOLD dataset of 53,000+ legal holdings](https://dl.acm.org/doi/abs/10.1145/3462757.3466088). In our work, we refer to this model as CaseLawBERT, and our re-trained model as InCaseLawBERT. |
|
|
|
### Usage |
|
Using the tokenizer (same as [CaseLawBERT](https://huggingface.co/zlucia/legalbert)) |
|
```python |
|
from transformers import AutoTokenizer |
|
tokenizer = AutoTokenizer.from_pretrained("law-ai/InCaseLawBERT") |
|
``` |
|
Using the model to get embeddings/representations for a sentence |
|
```python |
|
from transformers import AutoModel |
|
model = AutoModel.from_pretrained("law-ai/InCaseLawBERT") |
|
``` |
|
Using the model for further pre-training with MLM and NSP |
|
```python |
|
from transformers import BertForPreTraining |
|
model_with_pretraining_heads = BertForPreTraining.from_pretrained("law-ai/InCaseLawBERT") |
|
``` |
