Named Entity Recognition User and Programming Guide

# MeCabValidation

Set this parameter to `True` to use additional validation for Japanese names by using the MeCab Japanese tokenizer library. When you turn on MeCab validation, Named Entity Recognition excludes any matches where the MeCab library does not include the initial Named Entity Recognition match as a name. This validation applies only to names in Japanese script, not to Japanese names in Latin text.

To use this option, you must also set MeCabDicDir to provide the location of the MeCab dictionary files.

NOTE: Validation does not reduce performance during matching, but when you turn MeCab validation on, Named Entity Recognition might be slower to initialize.
