Simple dependency visualizer
Project description
deplacy
Simple dependency visualizer for spaCy, UniDic2UD, Stanza, NLP-Cube, etc.
Usage with spaCy
>>> import spacy
>>> nlp=spacy.load("en_core_web_sm")
>>> doc=nlp("The programmer was pleased by the nicely formatted parse tree.")
>>> import deplacy
>>> deplacy.render(doc)

>>> deplacy.serve(doc)
deplacy.render(doc,BoxDrawingWidth=1,EnableCR=False,CatenaAnalysis=True,file=None)
renders doc
on a terminal. For old terminals, whose Box Drawing characters are "fullwidth", BoxDrawingWidth=2
nicely works. For several languages with "proportional" characters, EnableCR=True
may work well. CatenaAnalysis=False
disables Immediate Catena Analysis.
deplacy.serve(doc,port=5000)
invokes a simple web-server to visualize doc
with SVG. Try to connect http://127.0.0.1:5000
with your local browser.
Usage with UniDic2UD
>>> import unidic2ud
>>> nlp=unidic2ud.load(None,"english-ewt")
>>> doc=nlp("The programmer was pleased by the nicely formatted parse tree.")
>>> d=str(doc)
>>> import deplacy
>>> deplacy.render(d)
