HateFlow backend

HateFlow can detect and classify inappropriate comments. It is available using an API documented here.

Installation

(tested on Ubuntu 20.04 and Python 3.8)

cd hateflow
pip3 install -r requirements.txt  --no-cache-dir

Training a model

python3 train.py

Evaluating the current model

python3 get_accuracy.py

Hosting the API

This section assumes an installation at /var/hateflow.

sudo mkdir /var/www/nltk_data
sudo mkdir /var/www/gensim-data
sudo chown www-data:www-data /var/www/*data

Apache has to be set up according to the system specific requirements.
