There are multiple chatbot development platforms like Dialogflow, Chatfuel, Manychat, IBM Watson, Amazon Lex, Mircrosft Bot framework, etc are available using which you can easily create your chatbots.
If you are new to chatbot development field and want to jump into it, this tutorial could be very helpful. Today I will take you through a detailed Dialogflow tutorial to develop your Resume Chatbot for Google Assistant.
About Dialogflow
Dialogflow is a popular chatbot development platform by Google. It provides graphical interface to manage flow of chat conversation. The crucial part of any chatbot is NLP (Natural Language Processing). The system should be able to process the input provided by users and extract meaning/context out of it. And one reason to select Dialogflow for creating this chatbot is taking advantage of Google’s highly superior NLP.
Dialogflow supports voice assistants like google assistant and amazon alexa.
Also, another big benefit of Dialogflow is that, once we develop a chatbot, we can integrate it with messaging platforms like Facebook, Skype, Twitter, Telegram, Line, Kik, Slack, Amazon Alexa, etc.
Update: We are now making the resume agent available as zip file. You can simply download it and import in your agent. Just sign up below to download the agent.
Let’s begin the Resume Chatbot development.
1. Google signup
To start using Dialogflow you need to have a Google Account. If you are already using gmail, then you can login using that account. Or you can create a new Google account.
After logging in you will be redirected to account setting page. Where you can select your country and choose email preferences as per your choice. You have to check the terms of service checkbox and click Accept button to proceed further.
Now you will land on welcome page of Dialogflow to kickoff your journey in exciting world of chatbot development.
2. Agent creation
To start with a new chatbot development in Dialogflow, we need to create an agent.
Provide a name for your agent and select the default timezone. Choose default language as per your preference.
3. Intents
Intents are basic building blocks of chatbot in Dialogflow. Intents map user input to responses. Dialogflow provides two default intents ‘Default Welcome Intent’ and ‘Default Fallback Intent’ for each agent you create.
Let’s have a look at what these default intents do.
a. Default Fallback Intent
When we create a new agent, Default Fallback Intent is automatically configured with various responses. Default Fallback Intent is called when user’s input does not match with any other intent.
We can change text responses in the Default Fallback Intent. When user enters input and that doesn’t match with any intent the
Default Fallback Intent select random response from the list of responses.
b. Default Welcome Intent
Default Welcome Intent is automatically configured with various training phrases and responses. This intent will be triggered when user starts interaction with our chatbot. Even when he hasn’t provided any input this intent will be invoked.
Now click on Default Welcome Intent. You can see Contexts, Events, training phrases, Action and parameters and Responses.
We can start building our bot by adding Training phrases and Responses
Training Phrases are used for matching with user inputs
When User’s input matches with any of these training phrases Default welcome intent triggers.
Response will be returned randomly from the list of responses.
4. Create New Intent
To create a new intent either click on + symbol next to intents menu on left sidebar or click on “CREATE INTENT” button on top.
Enter Intent name and click on save button.
Under Training Phrases section, we can see textbox “Add user expression”. Enter your training phrases and click save button.
You need to enter training phrases as per the intent. You need to decide what type of user input will invoke this intent. For example, for this Introduction intent, I have added “tell me about yourself” and “introduce yourself”.
Now scroll down to responses section. Every intent must have at least one response. In the Text response box, type a response and press Enter. We can add multiple responses. Intent use random responses from the list you have entered. Don’t forget to click on save button otherwise your changes won’t take effect.
5. Rich Responses
In Dialogflow there are multiple types of responses not just simple Text Response. You can use it for different purposes to show off your information in better way. For example, at times you might need to display some image or list of items or external links, etc. In those cases Rich responses come handy.
As per the chat platform (Google Assistant, Facebook Messenger, Kik, Telegram, Slack, etc) there are different options for rich responses as not all types are supported on different chat platforms.
Let’s explore the rich responses options provided for Google Assistant using different intents we need to create for resume.
Now in responses section click on + symbol next to DEFAULT and select Google Assistant from list.
Click on “ADD RESPONSES” button. You can see different types of responses.
