simhash
A node module to calculate the simhash (http://matpalm.com/resemblance/simhash/)
Installation
npm install simhashExample
Simhash is hash that returns similar hash(es) for similar input - in contrast to other hashing algorithms.
// will use crc32 as crypto algorithm as standardvar simhash = require('simhash')(); var result1 = simhash(['a', 'list', 'of', 'a', 'couple', 'of', 'tokens']);// return1 is [0,0,0,1,0,0,1,1,1,0,1,1,0,1,1,0,1,0,0,0,1,1,0,1,0,1,0,1,0,0,1,0] var result2 = simhash(['a', 'list', 'of', 'a', 'couple', 'of', 'tokens', '!']);// result2 is [0,0,0,1,0,0,0,1,1,0,0,1,0,1,1,0,1,0,0,0,1,1,0,1,0,1,0,1,0,0,1,0]You can also choose to use another algoritm than the standard crc32 one
var simhash = require('simhash')('md5'); var result = simhash(['a', 'list', 'of', 'a', 'couple', 'of', 'tokens']);
