# CaseNormalization

The case conversion to use for all incoming text. To improve performance, use this parameter to convert all text to lowercase or uppercase before attempting to match text.

This parameter takes one of the following values:

- None. No case conversion.
- Lower. All incoming text is converted to lowercase.
- Upper. All incoming text is converted to uppercase.

If your grammar file consists of only lowercase or only uppercase characters but your text is mixed case, you can improve performance by setting `CaseNormalization` to `Lower` or `Upper` respectively. This provides a greater performance improvement than setting MatchCase to `False`.

If you set this parameter to `Lower` or `Upper`, set MatchCase to `True`.

NOTE: When using the Named Entity Recognition Server Sentiment Analysis grammars, OpenText recommends that you set `CaseNormalization` to `Lower` and MatchCase to `True` to ensure optimal performance.

NOTE: You can override the value of this parameter for specific actions by setting the CaseNormalization action parameter.

Type: | String
Default: | None
Required: | No
Configuration Section: | Eduction
Example: | `CaseNormalization=lower`
