# Topic Classifier

The topic classifier works hand-in-hand with the [taxonomy agent](/about/agents/ai-insights/taxonomy.md). With this classifier, you can classify your data into the topics from a taxonomy.

## Configuration

This classifier shares all of the [common classifier configuration options](/about/agents/classifiers.md#common-configuration), with the exception of "Allowed tags." If you would like to prevent classifying your data certain topics, you can go to linked taxonomy and exclude those topics. In addition, the configuration also contains the following setting:

### Taxonomy run

This setting allows you to choose which [taxonomy run](/about/agents/ai-insights/taxonomy.md#taxonomy-runs) to use for classifying your documents. When you select one of your taxonomy agents, you will have the option to either use the agent's default run, or select a specific run. You will see a ★ star next to the run that is currently the default run. If the taxonomy agent is configured to use the latest successful run as its default output, this may change when it runs again.
