### New Features

- A new classification method has been added to allow you to classify your documents by using the structured information in fields. Structured classification analyzes a document and generates weights for how it compares to each structured category that you include in the structured classifier.

  Structured classification does not require any special configuration. Category uses the contents of `ParametricType` fields in the documents that you use to train the structured categories, and classifies documents according to this structured data.

  Category includes the following new actions to allow you to create and use the structured categories and structured classifiers:

  -     StructuredCategoryCreate

  -     StructuredCategoryDelete

  -     StructuredCategoryList

  -     StructuredClassifierCreate

  -     StructuredClassifierDelete

  -     StructuredClassifierList

  -     StructuredClassifierQuery

  For more information about these actions, and how to use structured classification, refer to the IDOL Category Component Help.
