String Similarity Algorithms
Usage
This package can be used when need to check how similar two words are. You can choose among some implemented algorithms that suits your best use case.
Below you will find all the implemented algorithms and when to use each. You can import a specific algorithm or use the strinSimilarity function.
It is very useful when you need different parameters for the same algorithm, such as jaroWinkler.
import stringSimilarity, { sorensenDice } from "string-similarity-alg";
const jaroWinklerResult = stringSimilarity("jaro-winkler").compare("game of thrones", "lord of the rings");
const sorensenDiceResult = sorensenDice.compare("game of thrones", "lord of the rings");Installation
You can install this package using populars package managers:
npm
npm install string-similarity-alg
yarn
yarn add string-similarity-alg
pnpm
pnpm add string-similarity-alg
Algorithms
| Algorithm | Since | Best use case | Example |
|---|---|---|---|
| Levenshtein | 1.0.0 | Small strings / similar words | farmville / faremviel |
| Soresen-Dice | 1.0.0 | Fuzzy matching, very mispelled words or poorly written | user-home-page.component.ts / usrhompcomp |
| Jaro-Winkler | 1.0.0 | Same as Jaro similarity, gives more weight to strings that have the same first letters | - |
| Jaro Similarity | 1.0.0 | General purpose, use this if you don't think any of the others are valid | - |
