How to use Pretrained Models
Online
You can follow this approach to use Spark NLP pretrained models:
# load NER model trained by deep learning approach and GloVe word embeddings
ner_dl = NerDLModel.pretrained('ner_dl')
# load NER model trained by deep learning approach and BERT word embeddings
ner_bert = NerDLModel.pretrained('ner_dl_bert')
The default language is en, so for other laguages you should set the language:
// load French POS tagger model trained by Universal Dependencies
val french_pos = PerceptronModel.pretrained("pos_ud_gsd", lang="fr")
// load Italain LemmatizerModel
val italian_lemma = LemmatizerModel.pretrained("lemma_dxc", lang="it")
Offline
If you have any trouble using online pipelines or models in your environment (maybe it’s air-gapped), you can directly download them for offline use.
After downloading offline models/pipelines and extracting them, here is how you can use them iside your code (the path could be a shared storage like HDFS in a cluster):
- Loading
PerceptronModelannotator model inside Spark NLP Pipeline
val french_pos = PerceptronModel.load("/tmp/pos_ud_gsd_fr_2.0.2_2.4_1556531457346/")
.setInputCols("document", "token")
.setOutputCol("pos")
