Spacy API
The system can operate as a pipeline add-in to spaCy that attaches to a span
or doc
To use as an extension, you need spaCy version 2.0 or later.
Functions
The function setup_spacy_extension()
attaches a seqeuence-to-graph inference function to the
spaCy span
and doc
objects. When working with these objects, there is a new method <object>._.to_amr()
.
Note the ._.
that spaCy uses to delineate add-on functions from native spaCy functions for
these objects.
Example
import amrlib
import spacy
amrlib.setup_spacy_extension()
nlp = spacy.load('en_core_web_sm')
doc = nlp('This is a test of the SpaCy extension. The test has multiple sentences.')
# The following are roughly equivalent but demonstrate the different objects.
graphs = doc._.to_amr()
for graph in graphs:
print(graph)
for span in doc.sents:
graphs = span._.to_amr()
print(graphs[0])
