bayes: A Naive-Bayes classifier for node.js
bayes takes a document (piece of text), and tells you what category that document belongs to.
What can I use this for?
You can use this for categorizing any text content into any arbitrary set of categories. For example:
- is an email spam, or not spam ?
- is a news article about technology, politics, or sports ?
- is a piece of text expressing positive emotions, or negative emotions?
npm install bayes
var bayes = require('bayes') var classifier = bayes() // teach it positive phrases classifier.learn('amazing, awesome movie!! Yeah!! Oh boy.', 'positive') classifier.learn('Sweet, this is incredibly, amazing, perfect, great!!', 'positive') // teach it a negative phrase classifier.learn('terrible, shitty thing. Damn. Sucks!!', 'negative') // now ask it to categorize a document it has never seen before classifier.categorize('awesome, cool, amazing!! Yay.') // => 'positive'
Returns an instance of a Naive-Bayes Classifier.
Teach your classifier what
text belongs to. The more you teach your classifier, the more reliable it becomes. It will use what it has learned to identify new documents that it hasn't seen before.
category it thinks
text belongs to. Its judgement is based on what you have taught it with .learn().
