node-word2vec-native

Port of the word2vec distance program to a native node.js addon

Installation

Install it from npm

npm install word2vec-native

Usage

This addon does not train vectors. You may use this to load an existing binary word2vec model file from disk. Once the model is loaded, you may perform the following two operations: get and compare.

var distance = require('word2vec-native');

distance.open('my-word2vec-model.bin',function(err){
    if(!err) {
        console.log(distance.compare("foo","bar"));
        console.log(distance.get("foo"));
    }
});

Get

Given a single term, returns a list of the most similar terms.

Compare

Given two terms, returns the cosine distance between their respective vectors.

See the test.js code for an example
