Interactive Clustering

Python package used to apply NLP interactive clustering methods.

Quick description

Interactive clustering is a method intended to assist in the design of a training data set.

This iterative process begins with an unlabeled dataset, and it uses a sequence of two substeps :

1. the user defines constraints on the data ;

2. the machine performs data partitioning using a constrained clustering algorithm.

Thus, at each step of the process :

• the user corrects the clustering of the previous steps using constraints, and

• the machine offers a corrected and more relevant data partitioning for the next step.

The process use severals objects :

• a constraints manager : its role is to manage the constraints annotated by the user and to feed back the information deduced (such as the transitivity between constraints or the situation of inconsistency) ;

• a constraints sampler : its role is to select the most relevant data during the annotation of constraints by the user ;

• a constrained clustering algorithm : its role is to partition the data while respecting the constraints provided by the user.

NB :

• This python library does not contain integration into a graphic interface.

• For more details, read the Documentation and the articles in the References section.

Requirements

Interactive Clustering requires Python 3.6 or above.

To install Python 3.6, I recommend using pyenv.

# install pyenv
git clone https://github.com/pyenv/pyenv ~/.pyenv

# setup pyenv (you should also put these three lines in .bashrc or similar)
export PATH="${HOME}/.pyenv/bin:${PATH}"
export PYENV_ROOT="${HOME}/.pyenv"
eval "$(pyenv init -)"

# install Python 3.6
pyenv install 3.6.12

# make it available globally
pyenv global system 3.6.12

Installation

With pip:

# install package
python3 -m pip install cognitivefactory-interactive-clustering

# install spacy language model dependencies (the one you want, with version "^2.3")
python3 -m spacy download fr_core_news_sm-2.3.0 --direct

With pipx:

# install pipx
python3 -m pip install --user pipx

# install package
pipx install --python python3 cognitivefactory-interactive-clustering

# install spacy language model dependencies (the one you want, with version "^2.3")
python3 -m spacy download fr_core_news_sm-2.3.0 --direct

NB : Other spaCy language models can be downloaded here : spaCy - Models & Languages. Use spacy version "^2.3".
