# similarity_check

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

## Installation

Use the package manager [pip](https://pip.pypa.io/en/stable/) to install similarity_check.

```bash
pip install similarity_check 
```

## Usage
### sentence tranformer
```python
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](https://www.sbert.net/).
* 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.
  * returns: a data frame with 3 columns (source, target, score), and two extra columns for each extra match (target_2, score_2 ...)
