# AutoCategorizeLabeller

A processor that determines which categories, if any, to apply to a particular input document. This processor adds a metadata field to a document for every category that the processor determines the document belongs to.

The processor holds documents in a queue, waiting to successfully identify the categories. If the processor successfully identifies categories for these documents, it processes and labels the documents. If not, it discards the documents.

## Properties

Name | Default Value | Description
--- | --- | ---
Category Host |  | The host of the Category component to use to categorize documents.
Category Port |  | The port of the Category component to use to categorize documents.
Min Weight | 50 | The minimum weight/score required for a category result for a document for it to be regarded as a match.
Distributed Cache Service |  | The identifier of the Distributed Cache Service used to communicate state between the AutoCategorizeGenerator processor and the AutoCategorizeLabeller processor.

NOTE: The template does not include the `DistributedMapCacheServer` controller service that is required to make it work. You must set one of these up yourself in your NiFi ingestion process, and configure both processors to use it.

The `DistributedMapCacheServer` is a standard NiFi service. For more information, see https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-distributed-cache-services-nar/1.5.0/org.apache.nifi.distributed.cache.server.map.DistributedMapCacheServer/index.html.

## Relationships

Name | Description
--- | ---
success | Successfully processed FlowFiles are routed to this relationship; that is, when the processor successfully adds a category label.
