# Extraction

Eduction extraction is the process of matching and retrieving entities from text, according to the rules in your grammars.

To run Eduction, you send a text file, or the raw text, to the Eduction engine (you can do this in several ways, see Eduction Architecture). The Eduction configuration specifies the grammars and entities that you want to match. Eduction identifies each instance of the requested entity, and returns an XML list of matches.

By default, Eduction returns the matched entity, with some additional information about the match, such as a confidence score for the accuracy of the match. It can also identify components of the entity match, such as the parts of a social security number or phone number (see Components).
