Designing Conversational Flows for Your Chatbot

By Bill Sharlow

Day 4: Building an AI Chatbot from Scratch

Welcome back to our 10-day journey in creating your very own AI chatbot! We’ve covered setting up our development environment, understanding Natural Language Processing (NLP), and choosing a framework. Today, we’ll delve into the crucial aspect of designing conversational flows for your chatbot.

The Significance of Conversational Flows

A well-designed conversational flow ensures that your chatbot can handle user interactions in a logical and intuitive manner. Think of it as creating a roadmap for the conversations your chatbot will have with users. This involves defining the structure, decisions, and responses within your chatbot.

Creating a Basic Flowchart

Let’s start by creating a basic flowchart for our chatbot. This will serve as a visual representation of how the chatbot will navigate through different user inputs and provide appropriate responses. Use pen and paper or a digital tool to sketch out the flowchart.

Example Flowchart:

  1. User Input: Greeting
  • Chatbot Response: Warm welcome and introduction to the chatbot’s capabilities.
  1. User Input: Asking for Information
  • Chatbot Response: Request clarification on the information needed and provide relevant details.
  1. User Input: Expressing Thanks
  • Chatbot Response: Express gratitude and ask if there’s anything else the user needs.

This is a simplified example, and your flowchart can be as detailed as your chatbot’s complexity requires.

Translating the Flowchart into Code

Now that we have a visual representation of our conversational flow, it’s time to translate it into code using the chosen framework. Most frameworks provide tools for defining dialogues, intents, and responses.

Example Code (Rasa):

# domain.yml

  - greet
  - ask_info
  - express_thanks

    - text: "Hello! How can I assist you today?"

    - text: "Sure, I can help with that. What information are you looking for?"

    - text: "You're welcome! Is there anything else I can help you with?"

Testing Your Conversational Flow

After implementing the code, it’s essential to test your chatbot’s conversational flow. Interact with your bot using various inputs to ensure it responds appropriately and follows the designed flow.

Congratulations on completing Day 4! Tomorrow, we’ll focus on adding intelligence to our chatbot using machine learning. Share your flowcharts, code snippets, and experiences in the comments. Happy coding!
