- Understanding concepts of building chatbots with DialogFlaw & Wit•ai
- Building chatbots for Facebook Messenger
- Natural Language Processing with DialogFlow
- Deploying your chatbot in Heroku application platform
Let's get started with our first project using Google Dialogflow. So what is an intent? An intent is a way to understand what the user is actually saying. So that's how the intents work in chatbot development and Natural Language Understanding.
The first step to creating a Messenger bot is to create a server that will be provided as a webhook when setting up the bot. The webhook provides the core of your chatbot experience as it is how your bot gets notified of the various interactions and events that happen, including when someone sends a message.
Setting up a new wit.ai chatbot project and training it with a few training examples.
Intents and entities are the basis on which wit.ai (or any other NLP tool) can parse data from your user. Intents represent a mapping between what a user says and what action should be taken by your software.
Example: If a user types out 'What's the weather in San Francisco?', the intent here is weather.
Entities represent concepts that are often specific to a domain as a way of mapping natural language phrases to canonical phrases that capture their meaning. Entities are a tool for extracting parameter values from natural language inputs.
Example: In a weather bot, a user can query the bot and ask for the weather in a particular city. A typical query can look like: 'What's the weather in London?' and the bot will return with a weather report. Other queries can be for the weather in Bangalore, Paris, Stockholm or any other location. Thus the domain that is common to all these queries is location, which is the entity here.
- Its necessary to have basic programming knowledge on Node JS
Do you want to create a talking chatbot that interact with your visitors? In this tutorial, you will learn how to create a Facebook chatbot with Node.JS using DialogFlow and Wit.AI platforms. Both DialogFlow and Wit.AI provide several Natural Language Processing functions that parse user input and match them to the right response. Implementing NLP in your bot can be pretty difficult, but there are several platforms that make it much easier to create a Facebook Messenger bot.
DialogFlow (formerly Api.AI, Speaktoit) is a Google developer of human–computer interaction technologies based on natural language conversations. Dialogflow is backed by Google and runs on Google Cloud Platform.
In this DialogFlow Node.JS tutorial, you will learn how to build a Facebook Messenger chatbot that incorporates NLP with Dialogflow and deploy it to Facebook.
Wit.AI makes it easy for developers to build chatbot applications and devices that you can talk or text to. Wit.AI is a natural language processing (NLP) tool that helps developers get structured data from chat or voice. Wit.AI makes it easy to build NLP into your chat bot, that learns from every interaction. If you want to build a Facebook bot even if you have not before, Wit.AI would be a great option.
In this Wit.AI Node.JS tutorial, you will learn how to train a chatbot using wit.AI by creating intents and entities for your chatbot data to build a Facebook Messenger chatbot.
This chatbot course will help you:
Use DialogFlow to build a chatbot.
Use Wit.AI to build a chatbot.
Understand intents and entities.
Build a Facebook Messenger bot.
Deploy chatbot apps to cloud platforms such as Heroku.
