Summary: ToneTint is a Python package that provides an intuitive way to perform sentiment analysis on text data and visualize the results. It splits the input text into manageable chunks, analyzes each chunk using a pre-trained sentiment analysis model, and highlights the text with background colors corresponding to the sentiment. Additionally, it displays tooltips with detailed sentiment scores when hovering over each text chunk.

**ToneTint** is a Python package that provides an intuitive way to perform sentiment analysis on text data and visualize the results. It splits the input text into manageable chunks, analyzes each chunk using a pre-trained sentiment analysis model, and highlights the text with background colors corresponding to the sentiment. Additionally, it displays tooltips with detailed sentiment scores when hovering over each text chunk.

## Features

- **Sentiment Analysis**: Uses pre-trained models to analyze the sentiment of text chunks.
- **Color-Coded Visualization**: Highlights text with colors representing positive, negative, or neutral sentiments.
- **Opacity Adjustment**: Adjusts the opacity of the highlight based on the confidence score of the sentiment prediction.
- **Interactive Tooltips**: Displays sentiment labels and scores when hovering over text chunks.
- **Customizable Colors**: Allows customization of highlight colors for different sentiments.
- **Flexible Text Chunking**: Splits text into sentences and further into chunks of specified sizes for detailed analysis.

## Installation

You can install **ToneTint** via pip:

```bash
pip install tonetint
```

Alternatively, you can clone the repository and install it manually:

```bash
git clone https://github.com/janduplessis883/tonetint_package.git
cd tonetint_package
python setup.py install
```

## Usage

### Basic Example

```python
from tonetint.sentiment_visualizer import ToneTint

# Initialize the visualizer
visualizer = ToneTint()

# Your input text
text = "I love sunny days. However, I hate the rain. The weather today is okay."

# Display the sentiment visualization
visualizer.display(text)
```

This code will display your text with:

- **Positive sentiments** highlighted in green.
- **Negative sentiments** highlighted in red.
- **Neutral sentiments** highlighted in yellow.

Hovering over each text chunk will show a tooltip with the sentiment label and confidence score.

### Customization

**Customizing Highlight Colors**

You can specify custom colors for positive, negative, and neutral sentiments by passing a dictionary to the `ToneTint` constructor:

```python
custom_colors = {
        "POS": "#aec867",  # Green
        "NEG": "#e8a56c",  # Red
        "NEU": "#f0e8d2",  # Yellow
}

visualizer = ToneTint(colors=custom_colors)
```

**Adjusting Chunk Size**

You can adjust the chunk size (number of words per chunk) for more granular or broader analysis:

```python
visualizer = ToneTint(chunk_size=10)
```

**Using a Different Model**

You can specify a different pre-trained model for sentiment analysis:

```python
visualizer = ToneTint(model_name='nlptown/bert-base-multilingual-uncased-sentiment')
```

## Dependencies

- **Python 3.6 or higher**
- **Transformers**: For using pre-trained sentiment analysis models.
- **NLTK**: For text tokenization.
- **IPython**: For displaying HTML in Jupyter notebooks.
- **Torch**: Required by some Transformer models.
- **SentencePiece**: For certain tokenizer models.

You can install the dependencies via pip:

```bash
pip install transformers nltk ipython torch sentencepiece
```
