# BertForStorySkillClassification

## Model Overview
`BertForStorySkillClassification` is a BERT-based text classification model designed to categorize story-related questions into one of the following 7 classes:
1. **Character**
2. **Setting**
3. **Feeling**
4. **Action**
5. **Causal Relationship**
6. **Outcome Resolution**
7. **Prediction**

This model is suitable for applications in education, literary analysis, and story comprehension.

## Model Architecture
- **Base Model**: `bert-base-uncased`
- **Classification Layer**: A fully connected layer on top of BERT for 7-class classification.
- **Input**: Question text (e.g., "Who is the main character in the story?")、QA text (e.g. "why could n't alice get a doll as a child ? \<SEP> because her family was very poor ")、 QA pair + Context(e.g. "why could n't alice get a doll as a child ? \<SEP> because her family was very poor \<context> alice is ... ")
- **Output**: Predicted label and confidence score.

## Quick Start

### Install Dependencies
Ensure you have the `transformers` library installed:
```bash
pip install transformers
```

### Load Model and Tokenizer

```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("curious008/BertForStorySkillClassification")
tokenizer = AutoTokenizer.from_pretrained("curious008/BertForStorySkillClassification")
```

### Use the predict Method for Inference

```python
# Single text prediction
result = model.predict(
    texts="Where does this story take place?",
    tokenizer=tokenizer,
    return_probabilities=True
)
print(result)
# Output: [{'text': 'Where does this story take place?', 'label': 'setting', 'score': 0.93178}]

# Batch prediction
results = model.predict(
    texts=["Why is the character sad?", "How does the story end?","why could n't alice get a doll as a child ? <SEP> because her family was very poor "],
    tokenizer=tokenizer,
    batch_size=16,
    device="cuda"
)
print(results)
"""
output:
[{'text': 'Why is the character sad?', 'label': 'causal relationship'},
 {'text': 'How does the story end?', 'label': 'action'},
 {'text': "why could n't alice get a doll as a child ? <SEP> because her family was very poor ",
  'label': 'causal relationship'}]
"""
```

## Training Details
### Dataset
