Annif is an automated subject indexing toolkit. It was originally created as a statistical automated indexing tool that used metadata from the Finna.fi discovery interface as a training corpus.

This repo contains a rewritten production version of Annif based on the prototype. It is a work in progress, but already functional for many common tasks.

Basic install

You will need Python 3.6+ to install Annif.

The recommended way is to install Annif from PyPI into a virtual environment.

python3 -m venv annif-venv
source annif-venv/bin/activate
pip install annif

You will also need NLTK data files:

python -m nltk.downloader punkt

Start up the application:

annif

See Getting Started in the wiki for more details.

Docker install

You can use Annif as a pre-built Docker container. Please see the wiki documentation for details.

Development install

A development version of Annif can be installed by cloning the GitHub repository.

Installation and setup

Clone the repository.

Switch into the repository directory.

Create and activate a virtual environment (optional, but highly recommended):

python3 -m venv venv
. venv/bin/activate

Install dependencies (including development) and make the installation editable:

pip install .[dev]
pip install -e .

You will also need NLTK data files:

python -m nltk.downloader punkt

Start up the application:

annif

Unit tests

Run . venv/bin/activate to enter the virtual environment and then run pytest. To have the test suite watch for changes in code and run automatically, use pytest-watch by running ptw.
