nltk StanfordNERTagger : NoClassDefFoundError: org/slf4j/LoggerFactory (In Windows)

Question

NOTE: I am using Python 2.7 as part of Anaconda distribution. I hope this is not a problem for nltk 3.1.

I am trying to use nltk for NER as

import nl         


        

Answer 1

Current Stanford NER tagger version is not compatible with nltk because it requires additional jars that nltk cannot add to the CLASSPATH.

Instead prefer an older version of Stanford NER Tagger that will works perfectly fine like this one: http://nlp.stanford.edu/software/stanford-ner-2015-04-20.zip
