fasttext-native

fastText native bindings for ⬡.js

Forked from pragonauts's fast-text

Features

• Executing prediction models
• Searching nearest neighbour
• Prebuilt binaries for Linux and macOS (Windows is not supported by fastText)
• Tracking latest fastText upstream version (currently version 0.1.0)

Usage

Prediction

There is a simple class for executing prediction models:

const path = require('path')
const { Classifier } = require('fasttext-native')
 
const model = path.resolve(__dirname, './classification.bin')
 
const classifier = new Classifier(model)
 
classifier.predict('how it works', 1, (err, res) => {
  if (err) {
    console.error(err)
  } else if (res.length > 0) {
    const tag = res[0].label // __label__someTag
    const score = res[0].valuel // 1.3455345
  } else {
    console.log('No matches')
  }
})

Nearest neighbour

There is a simple class for searching nearest neighbours:

const path = require('path')
const { Query } = require('fasttext-native')
 
const model = path.resolve(__dirname, './skipgram.bin')
 
const query = new Query(model)
 
query.nn('word', 10, (err, res) => {
  if (err) {
    console.error(err)
  } else if (res.length > 0) {
    const tag = res[0].label // letter
    const score = res[0].valuel // 0.99992
  } else {
    console.log('No matches')
  }
})
