Brain NLU

You can train a multilabel (Brain) NLU classifier (indicating language) with utterances and their intents. Then you can give a different utterance, and get the classifications for each intent, sorted descending by the score value.

const { BrainNLU } = require('node-nlp');

async function main() {
  const classifier = new BrainNLU({ language: 'fr' });
  classifier.add('Bonjour', 'greet');
  classifier.add('bonne nuit', 'greet');
  classifier.add('Bonsoir', 'greet');
  classifier.add("J'ai perdu mes clés", 'keys');
  classifier.add('Je ne trouve pas mes clés', 'keys');
  classifier.add('Je ne me souviens pas où sont mes clés', 'keys');
  await classifier.train();
  const classifications = classifier.getClassifications('où sont mes clés');
  console.log(classifications);
  // [ { label: 'keys', value: 0.9076581467793369 },
  // { label: 'greet', value: 0.09234185322066314 } ]
}
main();

Or you can get only the best classification

const { BrainNLU } = require('node-nlp');

async function main() {
  const classifier = new BrainNLU({ language: 'fr' });
  classifier.add('Bonjour', 'greet');
  classifier.add('bonne nuit', 'greet');
  classifier.add('Bonsoir', 'greet');
  classifier.add("J'ai perdu mes clés", 'keys');
  classifier.add('Je ne trouve pas mes clés', 'keys');
  classifier.add('Je ne me souviens pas où sont mes clés', 'keys');
  await classifier.train();
  const classifications = classifier.getBestClassification('où sont mes clés');
  console.log(classifications);
  // { label: 'keys', value: 0.9076581467793369 }
}
main();```
