charactertrigramfuzzyset

Character trigram fuzzy set implementation providing cosine similarity-based fuzzy matching.

This library does that one thing on iterables of strings. Any beyond that–Levenshtein distance, scoring, bigram fallback, etc.–is left as an exercise to the reader.

Usage

import os.path
from timeit import timeit
import requests

# Retrieve a file containing around 470,000 English words
url = 'https://github.com/dwyl/english-words/raw/master/words.txt'
r = requests.get(url, stream=True)
words_path = os.path.expanduser('~/words.txt')
if not os.path.isfile(words_path):
    with open(words_path, 'wb') as f:
        for chunk in r.iter_content(chunk_size=1024):
            if chunk:
                f.write(chunk)

# Usage
import charactertrigramfuzzyset as ctfs
items = [line.rstrip() for line in open(words_path, 'r')]
fs = ctfs.CharacterTrigramFuzzySet(items)
fs.get('bryan')

# Profiling, generally around 10-20 ms per call on my machine
timeit("fs.get('bryan')", setup='''
import charactertrigramfuzzyset as ctfs
items = [line.rstrip() for line in open('{words_path}', 'r')]
fs = ctfs.CharacterTrigramFuzzySet(items)
'''.format(words_path=words_path), number=1000)
