# Eduction

The Eduction processor uses Named Entity Recognition (Eduction) to extract entities from text. An entity is a word, phrase, or block of information. For example, you can use Named Entity Recognition to extract names, addresses, telephone numbers, and dates from document content or metadata.

For more information about Named Entity Recognition and how to configure Named Entity Recognition, refer to the Named Entity Recognition User and Programming Guide.

TIP: The Eduction processor includes the resource files available with Named Entity Recognition (excluding those for matching personal data that are provided separately in the PCI, PHI, and PII packages). This means that for properties such as Resource Files or [MyPostProcessingTask] Script you can enter the name of a OpenText grammar file or Lua script, such as `address_eng.ecr` or `normalize_money.lua`. The processor will use the corresponding file from its resources directory.

## Properties

Name | Default Value | Description
--- | --- | ---
IDOL License Service |  | An IdolLicenseServiceImpl that provides a way to communicate with a Knowledge Discovery License Server.
Entity |  | A list of entities to extract. Specify a comma-separated list of values, or one value per line. To specify several entities, you can use wildcard expressions. For example: `place/city1/*,place/city2/*`. The `*` wildcard matches any number of characters, and the `?` wildcard matches a single character. You must also set the Resource Files property to the location of the resource files that contain your chosen entities.
Entity Field |  | A list of document fields in which to write the matches from Named Entity Recognition. The value of this property must have the same number of values as the Entity property. Specify a comma-separated list of values, or one value per line.
Resource Files |  | A list of compiled ECR files containing Named Entity Recognition grammar entries. At least one resource file is required. You can match multiple resource files with wildcard expressions. You can use the `*` wildcard to match any number of characters, or the `?` wildcard to match a single character. Specify a comma-separated list of values, or one value per line.
Search Fields | DRECONTENT | A list of document fields to search for entities, for example `DRECONTENT` or `DRETITLE`. Specify a comma-separated list of values, or one value per line.
Simple Output | False | A Boolean value that specifies whether to add only the matched text to the document fields specified by the Entity Field property. To add only the matched text, set this parameter to true. With the default value, false, the fields will have subfields that contain the matched text, the offset, and the score.
eduction_configuration_parameter_name |  | For more information about the configuration parameters that you can use to configure Named Entity Recognition, see Named Entity Recognition Configuration Parameters. Some of these must be set as dynamic properties. Some properties, for example `PostProcessingTaskN`, accept the name of a configuration section (so that you can configure more than one post processing task). When you configure associated properties, prefix the property names with the section name in square brackets. For example, if you set `PostProcessingTask` to `MyTask`, specify the associated script by setting a property named `[MyTask]Script`.

## Relationships

Name | Description
--- | ---
success | Successfully processed FlowFiles are routed to this relationship.
failure | FlowFiles that had an invalid or unknown format.
