Scoring tools for bracket tree banks.
Project description
PYEVALB
EVEVALB is a python version of Evalb which is used to score the bracket tree banks.
Installation
pip install PYEVALB
Examples
Score two corpus
from PYEVALB import scorer
gold_path = 'gold_corpus.txt'
test_path = 'test_corpus.txt'
result_path = 'result.txt'
scorer.evalb(gold_path, test_path, result_path)And the result would be:
ID | length | state | recall | prec | matched_brackets | gold_brackets | test_brackets | cross_brackets | words | correct_tags | tag_accracy

from PYEVALB import scorer
from PYEVALB import parser

gold_tree = parser.create_from_bracket_string(gold)
test_tree = parser.create_from_bracket_string(test)
result = scorer.score_trees(gold_tree, test_tree)
print('Recall =' + str(result.recall))
print('Precision =' + str(result.prec))And the result is:
Recall = 64.29
Precision = 56.25TODO
Remove the dependency of pytablewriter
Add more configurations, such as limiting the length of sentence.
