# Hengam: An Adversarially Trained Transformer for Persian Temporal Tagging

# Usage

You can use this model directly downloading the utils and requirements files and installing requirements:

```python
>>> ! wget https://huggingface.co/kargaranamir/Hengam/raw/main/utils.py
>>> ! wget https://huggingface.co/kargaranamir/Hengam/raw/main/requirements.txt
>>> ! pip install -r requirements.txt
```

and downloading the models HengamTransA.pth or HengamTransW.pth and building ner pipline:

```python
>>> import torch
>>> from huggingface_hub import hf_hub_download
>>> from utils import *

>>> # HengamTransW = hf_hub_download(repo_id="kargaranamir/Hengam", filename="HengamTransW.pth")
>>> HengamTransA = hf_hub_download(repo_id="kargaranamir/Hengam", filename="HengamTransA.pth")
```

```python
>>> # ner = NER(model_path=HengamTransW, tags=['B-TIM', 'I-TIM', 'B-DAT', 'I-DAT', 'O'])
>>> ner = NER(model_path=HengamTransA, tags=['B-TIM', 'I-TIM', 'B-DAT', 'I-DAT', 'O'])
>>> ner('.سلام من و دوستم ساعت ۸ صبح روز سه شنبه رفتیم دوشنبه بازار ')
