adaptjs

A nodejs wrapper around the Adapt Intent Parser from Mycroft, which converts natural language into structured intents based on intent definitions.

Installation

$ npm install --save adaptjs

Install MycroftAI/adapt as described in their README.

Example

"use strict";
const EngineBuilder = require("adaptjs").EngineBuilder;

let builder = new EngineBuilder();

builder.entity("WeatherKeyword", ["weather"]);
builder.entity("WeatherType", ["snow", "rain", "wind", "sleet", "sun"]);
builder.entity("Location", ["Seattle", "San Francisco", "Tokyo"]);

builder.intent("WeatherIntent")
	.require("WeatherKeyword", "weatherkey")
	.optionally("WeatherType")
	.require("Location");

let engine = builder.build();

engine.query("Whats the weather in San Francisco today?")
.then(intents => { console.log(intents); engine.stop(); })
.catch(error => { console.log(error); console.log(error.stack); engine.stop(); });

/* [ { intent_type: 'WeatherIntent',
    weatherkey: 'weather',
    Location: 'San Francisco',
    confidence: 0.4878048780487805,
    target: null } ] */

See examples/ for more examples of the API and MycroftAI/adapt for more information about the Adapt Intent Parser itself.

API

new EngineBuilder([adaptInstallationPath]): EngineBuilder
EngineBuilder.entity(name, arrayOfValues): Entity
EngineBuilder.regexEntity(pattern): RegexEntity
EngineBuilder.intent(name): Intent
EngineBuilder.build(): Engine

Intent.require(entity, [attributeName]): this
Intent.optionally(entity, [attributeName]): this

Engine.start()
Engine.stop()
Engine.isRunning(): bool
Engine.query(input): Promise

How it works

The EngineBuilder on the JavaScript side creates a definition of all entities and intents and passes it to a python child process as JSON. The python child process keeps running in the background and receives new input over stdin. You have to stop the child process manually using engine.stop().

If you have installed Adapt in a specific location (not your current-working-directory), then you can pass that path as the first argument of the EngineBuilder. This path should be absolute, because otherwise it will be relative out of node_modules/ which will lead to problems later on.
