Annif is a multi-algorithm automated subject indexing tool for libraries, archives and museums.

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.

Finto AI is a service based on Annif; see the source code of Finto AI and the 🤗 Hugging Face Hub collection containing the models Finto AI uses.

Basic install

Annif is developed and tested on Linux. If you want to run Annif on Windows or Mac OS, the recommended way is to use Docker (see below) or a Linux virtual machine.

You will need Python 3.9-3.12 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.

Shell compeletions

Annif supports tab-key completion in bash, zsh and fish shells for commands and options and project id, vocabulary id and path parameters.

To enable the completion support in your current terminal session use annif completion command with the option according to your shell to produce the completion script and source it. For example, run

source <(annif completion --bash)

To enable the completion support in all new sessions first add the completion script in your home directory:

annif completion --bash > ~/.annif-complete.bash

Then make the script to be automatically sourced for new terminal sessions by adding the following to your ~/.bashrc file (or in some alternative startup file):

source ~/.annif-complete.bash

For details and usage for other shells see Click documentation.

Docker install

You can use Annif as a pre-built Docker container image from quay.io/natlibfi/annif repository. Please see the wiki documentation for details.

Development install

A development version of Annif can be installed by cloning the GitHub repository. Poetry is used for managing dependencies and virtual environment for the development version.

See CONTRIBUTING.md for information on unit tests, code style, development flow etc. details that are useful when participating in Annif development.

Installation and setup

Clone the repository.

Switch into the repository directory.

Install pipx and Poetry if you don't have them. First pipx:

python3 -m pip install --user pipx
python3 -m pipx ensurepath

Open a new shell, and then install Poetry:

pipx install poetry

Poetry can be installed also without pipx: check the Poetry documentation.

Create a virtual environment and install dependencies:

poetry install

By default development dependencies are included. Use option -E to install dependencies for selected optional features (-E "extra1 extra2" for multiple extras), or install all of them with --all-extras. By default the virtual environment directory is not under the project directory, but there is a setting for selecting this.

Enter the virtual environment:

poetry shell

You will also need NLTK data files:

python -m nltk.downloader punkt

Start up the application:

annif
