# Entity Extraction (Eduction)

Knowledge Discovery Eduction allows you to extract entities from text. You can use Eduction as part of your ingest process to enrich the data before you index it into Knowledge Discovery, or you can use it separately.

Eduction is available in several different formats and packages, depending on how you want to use it in your Knowledge Discovery architecture:

- Eduction in ingest (CFS task or NiFi processor). This component is part of the Knowledge Discovery Ingest process, and allows you to extract entities from documents, and add the information to document fields before you index. This process can make it easier to search for particular information after you index.

- Eduction SDK. The SDK is available in C, Java, and .NET implementations, which allow you to program your own applications that use Eduction for entity extraction.

- Eduction Server. An ACI server, which you can use to perform Eduction with standard ACI requests.

The particular setup you use depends on your usage and your wider Knowledge Discovery architecture. For more information about which package to use, refer to the Eduction User and Programming Guide.

Eduction Server and the Eduction SDK are each available as a ZIP package, which you can download and install. See Knowledge Discovery Installation and Setup. The Eduction NiFi processor is a standard part of the NiFi Ingest package, and Eduction in CFS is available as part of a standard CFS installation. for more information about installing these packages, see Knowledge Discovery Ingest.

In addition to the Eduction package, you must install the Eduction grammars that you want to use. The grammars define the entities that you want to find. These are all available as a single Eduction grammars ZIP package. Your license determines which of the grammars you can use.

For more information about Eduction, refer to the Eduction User and Programming Guide. This guide includes information about the standard grammars. There is also a guide for the premium grammars, the Eduction Grammars User Guide.
