similarity-check 0.0.14

package for measuring the similarity of two texts

similarity_check

similarity_check is a Python package for measuring the similarity of two texts.

Installation

Use the package manager pip to install similarity_check.

pip install similarity_check 

Usage

sentence tranformer

from similarity_check.checkers import sentence_tranformer

X = ['test', 'remove test']
y =  ['tests', 'stop the test']

st = sentence_tranformer(X, y)
st.clean_data()
match_df = st.match(topn=2)

• sentence_tranformer(source_names, target_names, model=None):
  • source_names: a list of input texts to find closest match for.
  • target_names: a list of targets text to compare with.
  • model (optional): a sentence tranformer model to use instead of the default one for more details.
• sentence_tranformer.clean_data(remove_punct=True, remove_stop_words=True, stemm=False, lang='en'):
  • remove_punct: boolean flag to indicate whatever to remove punctuations.
  • remove_stop_words: boolean flag to indicate whatever to remove stop words.
  • stemm: boolean flag to indicate whatever to do stemming.
  • lang: language of the text to clean ('en', 'ar').
• sentence_tranformer.match(topn=1):
  • topn: number of matches to return.
  • return_match_idx: return an extra column for each match containing the index of the match within the target_names.
  • returns: a data frame with 3 columns (source, target, score), and two extra columns for each extra match (target_2, score_2 ...)
