losNLTK La documentación es bastante pobre en esta integración. Los pasos yoseguido fueron:

Descargarhttp://nlp.stanford.edu/software/stanford-postagger-full-2015-04-20.zip a/home/me/stanford

Descargarhttp://nlp.stanford.edu/software/stanford-spanish-corenlp-2015-01-08-models.jar a/home/me/stanford

Luego en unipython consola:

En [11]: importar nltk

In [12]: nltk.__version__
Out[12]: '3.1'

In [13]: from nltk.tag import StanfordNERTagger

Entonces

st = StanfordNERTagger('/home/me/stanford/stanford-postagger-full-2015-04-20.zip', '/home/me/stanford/stanford-spanish-corenlp-2015-01-08-models.jar')

Pero cuando intenté ejecutarlo:

st.tag('Adolfo se la pasa corriendo'.split())
Error: no se ha encontrado o cargado la clase principal edu.stanford.nlp.ie.crf.CRFClassifier

Lo mismo ocurre con elStandfordPOSTagger

NOTA: Necesito que esta sea la versión en español.NOTA: Estoy ejecutando esto enpython 3.4.3
