Build a chatbot for common questions

Building a chatbot for common questions involves a few key steps, which I’ll break down below:

1. Define the Purpose and Scope

First, you need to determine the scope of your chatbot. What kinds of common questions do you want it to answer? Examples could be:

• Customer service inquiries (order status, returns, shipping)

• Product FAQs (features, pricing, specifications)

• General information (company hours, contact details)

2. Gather Common Questions and Responses

Next, list out the common questions your chatbot will answer. This could include questions like:

• “What are your business hours?”

• “How can I return an item?”

• “Do you ship internationally?”

• “Where is my order?”

For each question, provide a concise and informative response.

3. Choose a Platform

You can choose from several platforms to build your chatbot. Some popular ones include:

• Dialogflow by Google

• Microsoft Bot Framework

• Chatfuel (for Facebook Messenger)

• ManyChat

• Rasa (open-source option)

4. Develop the Chatbot Flow

This is where you define the logic of how the bot will handle different scenarios. The flow typically looks something like this:

• User Input → Bot Response

• If the bot doesn’t understand the input, it should either ask for clarification or provide options.

A sample flow could look like:

• User: “What are your business hours?”

• Bot: “We are open from 9 AM to 5 PM, Monday to Friday. How can I assist you further?”

If the bot is unsure:

• User: “I need help with an order.”

• Bot: “Can you please provide more details? Are you looking for order status, returns, or something else?”

5. Natural Language Processing (NLP)

Integrate NLP so the bot can understand variations in user input. Tools like Dialogflow and Rasa help process text and map user queries to the right intents and responses.

For example:

• “What time do you open?” should trigger the same response as “When are you open?”

• “How do I return a product?” should lead to the return policy.

6. Build and Train the Chatbot

Once you have your chatbot logic and responses, you’ll start programming it or use a chatbot builder like the ones mentioned above.

For example, with Dialogflow:

• Create intents (e.g., “Business Hours”, “Return Policy”).

• Provide training phrases (e.g., “When do you close?”, “What are your working hours?”).

• Map responses (the actual text the bot will say).

7. Test the Chatbot

Make sure you test the bot thoroughly to ensure it responds accurately to various user inputs. Consider edge cases and questions that might be unclear.

8. Launch and Monitor

Once the chatbot is working as expected, deploy it to your website or platform. Keep track of its performance and continue improving it by adding new questions and fine-tuning the responses.

9. Provide Human Escalation

Include a fallback option for when the bot can’t handle a query. This could be an option for users to talk to a human representative.

Example Implementation

Here’s a simple example of a chatbot implementation using Dialogflow:

• Intent: Business Hours

  • Training Phrases: “When are you open?”, “What are your hours?”, “Are you open on weekends?”

  • Response: “We are open from 9 AM to 5 PM, Monday to Friday. We are closed on weekends.”

• Intent: Return Policy

  • Training Phrases: “How do I return a product?”, “What’s your return policy?”, “Can I return my order?”

  • Response: “You can return products within 30 days of purchase. Please visit our Returns page for more details.”

10. Future Enhancements

Once your chatbot is live, continue improving it by:

• Adding new intents based on real user queries.

• Integrating it with other services like order tracking systems.

• Using machine learning to improve the chatbot’s understanding over time.
