Similarity

Sentence

get_similar_pairs

from linguistics.similarity import Sentence

sentence_1 = Sentence('John Joseph Nicholson')
sentence_2 = Sentence('Nicholson, Jack')
print(sentence_1.get_similar_pairs(sentence_2))

produces:

[{'word_1': Nicholson,
  'word_2': Nicholson,
  'similarity': 1.0,
  'index_1': 2,
  'index_2': 0},
 {'word_1': John,
  'word_2': Jack,
  'similarity': 0.5,
  'index_1': 0,
  'index_2': 1},
 {'word_1': Joseph,
  'word_2': None,
  'similarity': 0,
  'index_1': 1,
  'index_2': None}]

get_unordered_similarity

print(sentence_1.get_unordered_similarity(sentence_2))
print(sentence_1.get_unordered_similarity(sentence_2, case_sensitivity=0, weights=[1, 1]))
print(sentence_1.get_unordered_similarity(sentence_2, case_sensitivity=0, weights=[2, 1]))
print(sentence_1.get_unordered_similarity(sentence_2, case_sensitivity=0, weights=[1]))
print(sentence_1.get_unordered_similarity(sentence_2, case_sensitivity=0, first_char_weight=1, weights=[1, 1]))

produces
