tonetint 0.0.6

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:

pip install tonetint

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

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

Usage

Basic Example

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:

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:

visualizer = ToneTint(chunk_size=10)

Using a Different Model

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

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:

pip install transformers nltk ipython torch sentencepiece
