intent-tools

Intent tools

Tools for processing intents from RASA JSONs to Facebook fast-text learning sets.

Because there is good GUI: Rasa NLU Trainer

CLI Usage

• Convert RASA json to fast-text learning set

$ intools jsonToText ./testData.json ./testData.txt

• Convert RASA json to fast-text learning set and multiply by entities

$ intools jsonToText -m ./testData.json ./testData.txt

• Make word vectors learning set from wiki XML export

$ intools wikiToText ./testData.xml ./testData.txt

Functions

jsonToText(input, output, [pipeline], [mapFn]) ⇒ Promise

Create fast-text learning set from Rasa intents json

wikiToText(input, output, [mapFn]) ⇒ Promise

Create a pretrained word vectors learning set from Wikipedia XML dump

normalize(str)

Preserves only letters (with or withour diacritics) and makes everything lowercased

MultiplicatorStream

Kind: global class

• MultiplicatorStream
  • new MultiplicatorStream()
  • new MultiplicatorStream(getVariants)

new MultiplicatorStream()

Multiplicates a learning set data with available entities information

Example

const path = require('path');
const { EntitiesFromJson, MultiplicatorStream, jsonToText } = require('intent-tools');

const from = path.resolve(process.cwd(), 'sample.json');
const to = path.resolve(process.cwd(), 'trainingData.txt');

const entities = new main.EntitiesFromJson(from);

const pipeline = [
    new MultiplicatorStream((cat, word) => entities.getWordList(cat, word))
];

entities.loadEntities()
    .then(() => main.jsonToText(from, to, pipeline))
    .catch(e => console.error(e));

new MultiplicatorStream(getVariants)

Param	Type
