Autotaggerᅠ

This module allows you to automatically assign taxonomy terms to nodes according to the text you have entered.

We can select for each type of content which taxonomy we want to use and in which text fields we want to search for matches.

Version 1 of the module only supports nodes. We are currently working on version 2 in which all types of content entities are supported.

How to use the module:

First, enable the autotagger module that provides the autotagging framework and also the provided example module.

Then you can configure your content type to accept a set of source fields and a destination taxonomy reference field to set the tags automatically.
Edit content type settings

Make sure you've terms on the vocabulary you checked on the destination:

When you create nodes of the configured type,the tags will be automatically assigned based on text coincidence.
