# tw-roberta-base-sentiment-FT

This model is a fine-tuned version of [cardiffnlp/twitter-roberta-base-sentiment](https://huggingface.co./cardiffnlp/twitter-roberta-base-sentiment) on the dataset [Sp1786/multiclass-sentiment-analysis-dataset] (https://huggingface.co./datasets/Sp1786/multiclass-sentiment-analysis-dataset).

The text classification task in this model is based on 3 sentiment labels.

## Full classification example:

```python
from transformers import pipeline

pipe = pipeline(model="delarosajav95/tw-roberta-base-sentiment-FT")
inputs = ["The flat is very nice but it's too expensive and the location is very bad.",
          "I loved the music, but the crowd was too rowdy to enjoy it properly.",
          "They believe that I'm stupid and I like waiting for hours in line to buy a simple coffee."
]
result = pipe(inputs, return_all_scores=True)

label_mapping = {"LABEL_0": "Negative", "LABEL_1": "Neutral", "LABEL_2": "Positive"}
for i, predictions in enumerate(result):
  print("==================================")
  print(f"Text {i + 1}: {inputs[i]}")
  for pred in predictions:
    label = label_mapping.get(pred['label'], pred['label'])
    score = pred['score']
    print(f"{label}: {score:.2%}")
```

Output:

```python
==================================
Text 1: The flat is very nice but it's too expensive and the location is very bad.
Negative: 0.09%
Neutral: 99.88%
Positive: 0.03%
==================================
Text 2: I loved the music, but the crowd was too rowdy to enjoy it properly.
Negative: 0.04%
Neutral: 99.92%
Positive: 0.04%
==================================
Text 3: They believe that I'm stupid and I like waiting for hours in line to buy a simple coffee.
Negative: 69.79%
Neutral: 30.12%
Positive: 0.09%
```
