@Deprecated(since="2026-04-30")
public class CoreNLPNERecogniser
extends Object
implements NERecogniser

Deprecated.

This version of the Apache Tika library is deprecated. Use your own version of Apache Tika.

This class offers an implementation of NERecogniser based on CRF classifiers from Stanford CoreNLP. This NER requires additional setup, due to runtime binding to Stanford CoreNLP. See Tika NER Wiki for configuring this recogniser.
