All Implemented Interfaces:

NERecogniser

public class MITIENERecogniser
extends Object
implements NERecogniser

This class offers an implementation of NERecogniser based on trained models using state-of-the-art information extraction tools. This NER requires additional setup, due to runtime binding to MIT Information Extraction. See Tika MITIE Wiki for configuring this recogniser.
