# Named entity recognition
|
3 |
+
|
4 |
+
## Model Description
|
5 |
+
|
6 |
+
This model is a fine-tuned token classification model designed to predict entities in sentences.
|
7 |
+
It's fine-tuned on a custom dataset that focuses on identifying certain types of entities, including biases in text.
|
8 |
+
|
9 |
+
## Intended Use
|
10 |
+
|
11 |
+
The model is intended to be used for entity recognition tasks, especially for identifying biases in text passages.
|
12 |
+
Users can input a sequence of text, and the model will highlight words or tokens or **spans** it believes are associated with a particular entity or bias.
|
13 |
+
|
14 |
+
## How to Use
|
15 |
+
|
16 |
+
The model can be used for inference directly through the Hugging Face `transformers` library:
|
17 |
+
|
18 |
+
```python
|
19 |
+
#check for inference
|
20 |
+
from transformers import AutoModelForTokenClassification, AutoTokenizer
|
21 |
+
import torch
|
22 |
+
|
23 |
+
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
|
24 |
+
|
25 |
+
# Load model directly
|
26 |
+
from transformers import AutoTokenizer, AutoModelForTokenClassification
|
27 |
+
|
28 |
+
tokenizer = AutoTokenizer.from_pretrained("newsmediabias/UnBIAS-Named-Entity-Recognition")
|
29 |
+
model = AutoModelForTokenClassification.from_pretrained("newsmediabias/UnBIAS-Named-Entity-Recognition")
|
30 |
+
|
31 |
+
model.eval()
|
32 |
+
model.to(device)
|
33 |
+
|
34 |
+
def predict_entities(sentence):
|
35 |
+
tokens = tokenizer.tokenize(tokenizer.decode(tokenizer.encode(sentence)))
|
36 |
+
inputs = tokenizer.encode(sentence, return_tensors="pt")
|
37 |
+
inputs = inputs.to(device)
|
38 |
+
|
39 |
+
outputs = model(inputs).logits
|
40 |
+
predictions = torch.argmax(outputs, dim=2)
|
41 |
+
|
42 |
+
id2label = model.config.id2label
|
43 |
+
return [(token, id2label[prediction.item()]) for token, prediction in zip(tokens, predictions[0])]
|
44 |
+
|
45 |
+
sentence = "due to your evil nature, i am kind of tired and want to get rid of such cheapters."
|
46 |
+
predictions = predict_entities(sentence)
|
47 |
+
for token, label in predictions:
|
48 |
+
print(f"Token: {token}, Label: {label}")
|
49 |
+
|
50 |
+
```
|
51 |
+
|
52 |
+
|
53 |
+
## Limitations and Biases
|
54 |
+
|
55 |
+
Every model has limitations, and it's crucial to understand these when deploying models in real-world scenarios:
|
56 |
+
|
57 |
+
1. **Training Data**: The model is trained on a specific dataset, and its predictions are only as good as the data it's trained on.
|
58 |
+
2. **Generalization**: While the model may perform well on certain types of sentences or phrases, it might not generalize well to all types of text or contexts.
|
59 |
+
|
60 |
+
It's also essential to be aware of any potential biases in the training data, which might affect the model's predictions.
|
61 |
+

+
## Training Data
|
63 |
+
|
64 |
+
