monkeylearn

monkeylearn-node

Official Node client for the MonkeyLearn API. Build and consume machine learning models for language processing from your Node apps.

Install

You can use npm to install the library:

npm install monkeylearn

Usage examples

Here are some examples of how to use the library in order to create and use classifiers:

var MonkeyLearn, ml, p, module_id, root_id, negative_id, positive_id, samples;

MonkeyLearn = require('monkeylearn');

// Use the API key from your account
ml = new MonkeyLearn('<YOUR API KEY HERE>');

// Create a new classifier
p = ml.classifiers.create('Test Classifier').then(function (res) {
    // Get the id of the new module    
    module_id = res.result.classifier.hashed_id
    
    // Get the classifier detail
    return ml.classifiers.detail(module_id);
}).then(function (res) {    
    // Get the id of the root node
    root_id = res.result.sandbox_categories[0].id
    
    // Create a negative category on the root node
    return ml.classifiers.categories.create(module_id, 'Negative', root_id);
}).then(function (res) {   
    // Get the id of the negative category
    negative_id = res.result.category.id
    
    // Create a positive category on the root node
    return ml.classifiers.categories.create(module_id, 'Positive', root_id);
}).then(function (res) {    
    // Get the id of the positive category
    positive_id = res.result.category.id
    
    // Now let's upload some samples
    samples = [['The movie was terrible, I hated it.', negative_id], ['I love this movie, I want to watch it again!', positive_id]];
    return ml.classifiers.uploadSamples(module_id, samples);
}).then(function (res) {    
    // Now let's train the module!
    return ml.classifiers.train(module_id);
}).then(function (res) {
    // Classify some texts
    return ml.classifiers.classify(module_id, ['I love the movie', 'I hate the movie'], true);
}).then(function (res) {    
    console.log(res.result);
});

You can also use the sdk with extractors and pipelines:

var MonkeyLearn = require('monkeylearn');
var ml = new MonkeyLearn('<YOUR API KEY HERE>');
var res = ml.extractors.extract('<Extractor ID>', ['Some text for the extractor.', 'Some more text']);
var res = ml.pipelines.run('<Pipeline ID>', {'input':[{'text': 'some text for the pipeline.'}]}, false);
