Annif-client

This is a minimal Python 3.x client library for accessing the Annif REST API which can be used for automated subject indexing and classification of text documents.

Dependencies

The library depends on the requests module which is used for HTTP/REST access. The easiest way to install requests is via pip:

pip install requests

or in some cases (e.g. Ubuntu systems with both Python 2 and 3):

pip3 install requests

How to use

The client library comes with examples demonstrating its usage. You can invoke the example simply by running the annif_client.py script.

You can install the annif_client module globally like this:

python3 setup.py install

In your own code, you can then import the AnnifClient class like this:

from annif_client import AnnifClient

# then you can create your own client
annif = AnnifClient()

Example invocation

Here is the output from a typical example session:

$ python3 annif_client.py
