# TangibleCharacters

A list of punctuation characters to treat as part of the word, rather than as word boundaries. By default, Named Entity Recognition treats almost all punctuation characters as word boundaries.

NOTE: You cannot specify spaces, returns, and tabs as `TangibleCharacters`.

This parameter has no effect when MatchWholeWord is set to `False`.

For more information on using `TangibleCharacters` to specify punctuation characters to match, or to match punctuation at the start of a match, refer to the Named Entity Recognition User and Programming Guide.

Type: | String
Default: | None
Required: | No
Configuration Section: | Any section that you have defined for Named Entity Recognition settings
Example: | `TangibleCharacters=-/\@`
