jellyfish
A python library for doing approximate and phonetic matching of strings.
About jellyfish
jellyfish is a Python library for approximate and phonetic matching of strings. It provides string-comparison functions including Levenshtein, Damerau-Levenshtein, Jaro, Jaro-Winkler, Hamming, Jaccard, and Match Rating Approach Comparison, along with phonetic encoders for American Soundex, Metaphone, NYSIIS, and Match Rating Codex.
Key features
- Calculates Levenshtein distance between two strings
- Calculates Damerau-Levenshtein distance between two strings
- Computes Jaro and Jaro-Winkler similarity scores
- Computes Hamming distance, Jaccard index, and Match Rating Approach Comparison
- Encodes strings with American Soundex and Metaphone
- Encodes strings with NYSIIS and Match Rating Codex
Best for: Python developers who need approximate string matching or phonetic encoding in their projects.
Good for
- Open source with MIT license stated in the repository
- Includes both string-comparison and phonetic-encoding algorithms
- Provides code examples for basic function calls
