Document Distance Problem - d(D1, D2)

The document distance problem has applications in finding similar documents, detecting duplicates (Wikipedia mirrors and Google) and plagiarism, and also in web search (D2 = query).

The idea is to define distance in terms of shared words.

Install

$ npm install --save document-distance

Usage

var fs = require('fs');
var documentDistance = require('document-distance');
 
fs.readFile('file1.txt', function(err, dataFile1) {
    if(err) throw err;
    
    fs.readFile('file2.txt', function(err, dataFile2) {
        if(err) throw err;
        
        documentDistance(dataFile1.toString(), dataFile2.toString()); //=> 0.8410686705679303
    });
});
