Class LingPipeNer

java.lang.Object

ws.palladian.extraction.entity.NamedEntityRecognizer

ws.palladian.extraction.entity.TrainableNamedEntityRecognizer

ws.palladian.extraction.entity.tagger.LingPipeNer

All Implemented Interfaces:

Tagger

public class LingPipeNer
extends TrainableNamedEntityRecognizer

This class wraps the LingPipe implementation of a Named Entity Recognizer. We wrapped the slowest but most accurate recognizer (CharLmRescoringChunker) since we are interested in the best possible results. LingPipe uses a "long-distance character language model-based chunker that operates by rescoring the output of a contained character language model HMM chunker.
