🐦 pigeonXT - Quickly annotate data in Jupyter Lab

PigeonXT is an extention to the original Pigeon, created by Anastasis Germanidis. PigeonXT is a simple widget that lets you quickly annotate a dataset of unlabeled examples from the comfort of your Jupyter notebook.

PigeonXT currently support the following annotation tasks:

  • binary / multi-class classification
  • multi-label classification
  • regression tasks
  • captioning tasks

Anything that can be displayed on Jupyter (text, images, audio, graphs, etc.) can be displayed by pigeon by providing the appropriate display_fn argument.

Additionally, custom hooks can be attached to each row update (example_process_fn), or when the annotating task is complete(final_process_fn).

There is a full blog post on the usage of PigeonXT on Towards Data Science.

Installation

PigeonXT obviously needs a Jupyter Lab environment. Futhermore, it requires ipywidgets. The widget itself can be installed using pip:

    pip install pigeonXT-jupyter

Currently, it is much easier to install due to Jupyterlab 3: To run the provided examples in a new environment using Conda:

    conda create --name pigeon python=3.9
    conda activate pigeon
    pip install numpy pandas jupyterlab ipywidgets pigeonXT-jupyter

For an older Jupyterlab or any other trouble, please try the old method:

    conda create --name pigeon python=3.7
    conda activate pigeon
    conda install nodejs
    pip install numpy pandas jupyterlab ipywidgets
    jupyter nbextension enable --py widgetsnbextension
    jupyter labextension install @jupyter-widgets/jupyterlab-manager

    pip install pigeonXT-jupyter

Starting Jupyter Lab environment:

    jupyter lab

Examples

Examples are also provided in the accompanying notebook.

Binary or multi-class text classification

Code:

    import pandas as pd
    import pigeonXT as pixt
    
    annotations = pixt.annotate(
        ['I love this movie', 'I was really disappointed by the book'],
        options=['positive', 'negative', 'inbetween']
    )

Multi-label text classification

Code:

    import pandas as pd
    import pigeonXT as pixt

    df = pd.DataFrame([
        {'example': 'Star wars'},    
        {'example': 'The Positively True Adventures of the Alleged Texas Cheerleader-Murdering Mom'},
        {'example': 'Eternal Sunshine of the Spotless Mind'},
        {'example': 'Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb'},    
        {'example': 'Killer klowns from outer space'},    
    ])

    labels = ['Adventure', 'Romance', 'Fantasy', 'Science fiction', 'Horror', 'Thriller']
    
    annotations = pixt.annotate(
        df, 
        options=labels, 
        task_type='multilabel-classification',
        buttons_in_a_row=3,
        reset_buttons_after_click=True,
        include_next=True,
        include_back=True,
    )

Image classification

Code:

    import pandas as pd
    import pigeonXT as pixt

    from IPython.display import display, Image

    annotations = pixt.annotate(
      ['assets/img_example1.jpg', 'assets/img_example2.jpg'],
      options=['cat', 'dog', 'horse'],
      display_fn=lambda filename: display(Image(filename))
    )

Audio classification

Code:

    import pandas as pd
    import pigeonXT as pixt

    from IPython.display import Audio 

    annotations = pixt.annotate(
        ['assets/audio_1.mp3', 'assets/audio_2.mp3'],
        task_type='regression',
        options=(1,5,1),
        display_fn=lambda filename: display(Audio(filename, autoplay=True))
    )
