# distilBert_NER_finer
This model is a fine-tuned version of [distilbert-base-cased](https://huggingface.co/distilbert-base-cased) on the [Finer-139](https://huggingface.co/datasets/nlpaueb/finer-139) dataset.
It achieves the following results on the evaluation set:
- Loss: 0.0198
- Precision: 0.9445
- Recall: 0.9640
- F1: 0.9541
- Accuracy: 0.9954
## Training and evaluation data
The training data consists of the 4 most widely available ner_tags from the Finer-139 dataset. The training and the test data were curated from this source accordingly
## Prediction procedure
```
from transformers import TAutoTokenizer
from optimum.onnxruntime import ORTModelForTokenClassification
import torch
def onnx_inference(checkpoint, test_data, export=False):
test_text = " ".join(test_data['tokens'])
print("Test Text: " + test_text)
tokenizer = AutoTokenizer.from_pretrained(checkpoint)
model = ORTModelForTokenClassification.from_pretrained(checkpoint, export=export)
inputs = tokenizer(test_text, return_tensors="pt")
outputs = model(**inputs).logits
predictions = torch.argmax(outputs, dim=2)
# Convert each tensor element to a scalar before calling .item()
predicted_token_class = [label_list[int(t)] for t in predictions[0]]
ner_tags = [label_list[int(t)] for t in test_data['ner_tags']]
print("Original Tags: ")
print(ner_tags)
print("Predicted Tags: ")
print(predicted_token_class)
onnx_model_path = "" #add the path
onnx_inference(onnx_model_path, test_data)
"""
Here the test_data should contain "tokens" and "ner_tags". This can be of type Dataset.
