The http backend allows Annif to delegate subject suggestion requests to an external system via communicating it with REST API. The target system can be either another Annif instance or a compatible service that implements the necessary functionality: a suggest method that accepts a document and returns a list of suggested subjects.

See for example MauiServer.

[http-en]
name=HTTP English
language=en
backend=http
endpoint=http://localhost:5000/v1/projects/yso-en/suggest
vocab=yso

The endpoint setting specifies a URL where requests for subject suggestions are POSTed.

Load a vocabulary:

annif load-vocab yso /path/to/Annif-corpora/vocab/yso-skos.ttl

Training is not possible.

Test with a single document:

cat document.txt | annif suggest http-en

Evaluate a directory full of files in fulltext document corpus format:

annif eval http-en /path/to/documents/
