HengamTagger

The HengamTagger is distributed as Parstdex package (will be continuously updated) and is available via pip.

HengamTransformer

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

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

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

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")

# 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 ')

Alos, in this github 4 different notebooks are provided to train and load the model. Click on the hyperlinks to open each in Google Colab.

• Inference and Test
  • Inference_HengamTransW.ipynb: In this notebook, HengamTransW.pth is downloaded from Hengam HuggingFace model card, and an inference is provided in the last cells.
  • Inference_HengamTransA.ipynb: In this notebook, HengamTransA.pth is downloaded from Hengam HuggingFace model card, and an inference is provided in the last cells.
• Train
  • Train_HengamTransW.ipynb: This notebook uses the HengamCorpus dataset uploaded on HuggingFace. Afterwards, the HengamTransW will be trained.
  • Train_HengamTransA.ipynb: This notebook uses the trained HengamTransW.pth downloaded from HuggingFace and then trains it on strong labeled data in an adverserial manner to produce HengamTransA.
