Pyramids: English

This package provides the English grammar configuration for the Pyramids parser.

Usage:

Code:

import time
from pyramids.categorization import Category
from pyramids_english.plugin import LANGUAGE

timeout = 5  # maximum time, in seconds
text = "This is a test."

(forests, emergency_disambiguation, parse_timed_out, disambiguation_timed_out) = \
        LANGUAGE.parse(text, timeout=time.time() + timeout)

for index, forest in enumerate(forests):
    forest = forest.restrict(Category('sentence'))
    if forest.has_gaps():
        # Gaps indicate that the input could not be fully parsed.
        break
    if forest.is_ambiguous():
        forest = forest.disambiguate()
    print("Interpretation #%s" % (index + 1))
    for graph in forest.get_parse_graphs(forest):
        print(graph)
        print()
    print()
