# Standard Grammar – Source

Named Entity Recognition includes standard grammar files in source form (XML) and their compiled equivalents (ECR). The source files import compiled Named Entity Recognition standard grammar files and illustrate sample usage. You can modify these XML source files and recompile them to customize a grammar for the needs of your Named Entity Recognition application.

The following table lists public entities defined in the XML source files. It excludes the public entities that are republished from the imported Named Entity Recognition ECR grammar files.

File | Entity | Description
--- | --- | ---
measure.xml | measure/all/eng | An editable collection of patterns that match length, area, volume, and mass.
money.xml1 When matching symbols in the money entities, the Named Entity Recognition option MatchWholeWord must be set to 0 (false). Otherwise, when encountering a string such as $10.70, Named Entity Recognition does not recognize that $ is the start of a token. Instead, it looks only for matches starting on the 1 and on the 7, and will not return $10.70. | money/all | All currency amounts. NOTE: This grammar file supports some English alphabetic numbers, for example, seven cents, $12 million, one hundred dollars, £5m.

The entities in this table incorporate the compiled Named Entity Recognition entities in combination with Named Entity Recognition XML grammar to create additional entities. The XML illustrates how to use the compiled Named Entity Recognition entities. You can modify these XML files and compile them into Named Entity Recognition ECR files that you can then use for specific applications.

The Named Entity Recognition grammar files have three advantages:

- Allows for fined-grained access to basic entities that include more complex entities. You can then customize the complex entities to increase the precision and recall of the matching process.
- Provides both the compiled ECR grammar files as well as source-form XML grammar files that reference them.
- Separate ECR files reduce the memory footprint and file size.
