Python Jaccard Examples

Example #1

File: test_char_metrics.py Project: parantak/decepticonlp

def test_jaccard_window(text1, text2, window, expected_result):
    jaccard_similarity = char_metrics.Jaccard()
    err = jaccard_similarity.calculate(text1, text2,
                                       ngrams=window) - expected_result
    assert -1e-5 < err < 1e-5

Example #2

File: test_char_metrics.py Project: parantak/decepticonlp

def test_jaccard_with_short_length():
    with pytest.raises(AssertionError):
        jaccard_similarity = char_metrics.Jaccard()
        jaccard_similarity.calculate("Word", "Wordy", ngrams=10, ignore=False)

Example #3

File: test_char_metrics.py Project: parantak/decepticonlp

def test_jaccard(text1, text2, expected_result):
    jaccard_similarity = char_metrics.Jaccard()
    err = jaccard_similarity.calculate(text1, text2) - expected_result
    assert -1e-5 < err < 1e-5
