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
	});
});
