How to do semantic matching in Python?

Question:

I am trying to use semantic matching in Python on a group of words.

Sample Input:

['error 1', '14_7error', 'err_87P', 'configuration 49-ñ', 'confi:p2g%']

Sample Output:

['error 1,14_7error,err_87P', 'configuration 49-ñ','confi:p2g%']

What I have tried:

I have tried using sklearn, but can get it to work, code:

from sklearn.feature_extraction.text import TfidfVectorizer

documents = ['error 1', '14_7error', 'err_87P', 'configuration 49-ñ', 'confi:p2g%']

tfidf = TfidfVectorizer().fit_transform(documents)
pairwise_similarity = (tfidf * tfidf.T).toarray()

I have also looked at:

But none of it has helped much.

Looking at your input data, it seems that your goal is not semantic matching, but string matching. You can use fuzzywuzzy to do that:

from fuzzywuzzy import process 
documents = ['error 1', '14_7error', 'err_87P', 'configuration 49-ñ', 'confi:p2g%']
results = [[i, process.extractOne(i, [x for x in documents if x != i])] for i in documents]

Results for best matches with matching score: [['error 1', ('14_7error', 71)], ['14_7error', ('error 1', 71)], ['err_87P', ('error 1', 43)], ['configuration 49-ñ', ('confi:p2g%', 60)], ['confi:p2g%', ('configuration 49-ñ', 60)]]
