# SkyWalkertT1/crypto_bert_sentiment

## 📌 Model Details

### Model Description

This is a BERT-based sentiment classification model fine-tuned on Turkish-language cryptocurrency-related comments. It predicts one of three sentiment classes: positive, neutral, or negative. This model was built using the Hugging Face 🤗 Transformers library and is suitable for analyzing sentiment in crypto communities, forums, or financial social media texts in Turkish.

- **Developed by:** [SkyWalkertT1 - Furkan Fatih Çiftçi]
- **Funded by:** Personal / Community Open Source
- **Shared by:** SkyWalkertT1
- **Model type:** BERT-based Sequence Classification
- **Language(s) (NLP):** Turkish
- **License:** Apache 2.0
- **Finetuned from model:** `dbmdz/bert-base-turkish-cased`
## 📚 Training Details

### Training Data

Dataset consists of labeled Turkish-language comments related to cryptocurrency, manually tagged with 3 sentiment labels.  
**The dataset used for training this model is proprietary and was created and labeled by the author.**  
The dataset shape is approximately `(1171, 2)` — indicating 1171 samples with 2 columns (text and label).
### Model Sources

- **Repository:** https://huggingface.co/SkyWalkertT1/my_crypto_comment_model

## 🔍 Uses

### Direct Use

- Turkish sentiment analysis on crypto/financial text
- Educational / experimental use for NLP in Turkish

### Downstream Use

- Integration into crypto sentiment bots
- Turkish language feedback systems
- Sentiment dashboards for crypto forums

### Out-of-Scope Use

- Use on non-Turkish text
- Medical, legal, or other high-risk domain sentiment prediction

## ⚠️ Bias, Risks, and Limitations

The model was trained on data specific to cryptocurrency sentiment in Turkish. It may not generalize to other domains. Model performance may vary depending on the writing style and slang usage.

### Recommendations

- Do not use this model for critical decision-making.
- Human validation should accompany any automated output.

## 🚀 How to Get Started with the Model

```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch

model_path = "SkyWalkertT1/my_crypto_comment_model"

tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForSequenceClassification.from_pretrained(model_path)

text = "Bugün piyasada büyük bir düşüş bekliyorum."
inputs = tokenizer(text, return_tensors="pt", padding=True, truncation=True)
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model.to(device)
inputs = {k: v.to(device) for k, v in inputs.items()}

with torch.no_grad():
    outputs = model(**inputs)

logits = outputs.logits
predicted_class = torch.argmax(logits, dim=1).item()
labels = ['negative', 'neutral', 'positive']

print(f"Prediction: {labels[predicted_class]}")
```
