11.6 Practical Exercises of Chapter 11: Introduction to Chatbots

11.6.1. Build a Simple Rule-Based Chatbot

Use the principles of rule-based chatbots discussed in this chapter to create a simple chatbot. It should be able to handle a small set of predefined inputs and provide appropriate responses. For example, it could be a chatbot for a fictional coffee shop that can handle questions about operating hours, menu items, and locations.

def coffee_shop_bot(user_input):
    if 'hours' in user_input:
        return "We're open from 8 AM to 8 PM every day."
    elif 'menu' in user_input:
        return "We serve coffee, tea, pastries, and sandwiches."
    elif 'location' in user_input:
        return "We're located at 123 Coffee St."
    else:
        return "Sorry, I didn't understand that."

11.6.2. Explore Intent Recognition with NLU Services

Services like Dialogflow, Wit.ai, and IBM Watson provide powerful NLU capabilities for intent recognition and entity extraction. Choose one of these services and create a simple chatbot that can recognize a few different intents.

11.6.3. Implement a Seq2Seq Model

As an advanced exercise, try implementing a seq2seq model for a chatbot. Use a dataset of conversation logs for training. This is a challenging task that will help you understand the complexities of dialogue systems.

11.6.4. Experiment with Pre-Trained Models

There are several pre-trained models available for chatbot development, such as GPT-3 and BERT. Try using one of these models to create a more advanced chatbot.

Remember, the most important part of these exercises is to understand the concepts behind each technique. Building these systems will help you understand the strengths and weaknesses of each approach, and will give you a strong foundation for further exploration in the field of chatbot development.
