Introduction to AI chat Bot
AI chat bot infracts through messaging, using artificially replicating AI powered patterns of humans.
Chatbot aka Chat Robot, it fundamentally allow to communicate between real human and that machine. it is programed using Natural Language Processing(NLP) to answer like a real world person.
When a chatbot receives a question it will process that with a predefined set of scripts and Machine Learning model. When the conversation reached to a point where it does not know the answer it will fallback to the human operator and it will learn the answers using the ML over the time it will respond to that questions.
What is DialogFlow
DialogFlow is a cloud based solution for build conversational bot powered by Google.
Module of DialogFlow
We need to understand below modules to built our chatbot, let's dive into DialogFlow.
- Knowledge Base
Agents are the virtual agent that communicates with the real humans and convert the message from the human to an structured data using natural language processing.
We can build multiple agents based on the types of conversation required.
Lets create our first agent by going here https://dialogflow.cloud.google.com/#/newAgent
Now we have created our first agent successfully.
When agents receives a message from the human, it will start classifying the message and try to find the intention of the message.
Every agent will have three types of intents
- Fallback Intents - Fallback to this if the message is not matched with any intents
- Welcome Intents - Initial message will me matched with this intent
- Regular Intents - Each agents will have many intents for classifying the message.
When a message is passed to the Intents it will try to exact the message using the types.
- System Entity - Predefined entity like date, number, time, etc,.
- Custom Entity - These are user defined for the complex use case.
In real world human agents, will have documentation about the product for referencing information, like manual guide for mobile operation.
In DialogFlow we have knowledge base for the virtual agents where we can input the documents or data which will be used to build the response to the end user.
Imagine that you run a restaurant and you need to book a table for dinner, this requires to check the table availability of the your system, This can be achieved by using the fulfilment service.
When the fulfilment is enabled for a intent and if that receives a message then this will look for the external response based on this the end user will get the response.
This is the output of the intent, If a agents received a message through telephone audio, then response can be converted into an audio and delivered to the end user.
- Google Assistant
- Dialogflow Messenger
- Dialogflow Phone Gateway
- Dialogflow Web Demo
- Hangouts Chat
- Facebook Messenger
By default DialogFlow support leading conversation platforms.
Now we have seen the fundamentals of the DialogFlow in overview. Let's deep dive into real world examples.
