What to Know to Build an AI Chatbot with NLP in Python

If the user isn’t sure whether or not the conversation has ended your bot might end up looking stupid or it will force you to work on further intents that would have otherwise been unnecessary. Chatbot, too, needs to have an interface compatible with the ways humans receive and share information with communication. That is what we call a dialog system, or else, a conversational agent. Natural Language Processing does have an important role in the matrix of bot development and business operations alike.


In line 6, you replace “chat.txt” with the parameter chat_export_file to make it more general. The clean_corpus() function returns the cleaned corpus, which you can use to train your chatbot. ChatterBot uses complete lines as messages when a chatbot replies to a user message. In the case of this chat export, it would therefore include all the message metadata. That means your friendly pot would be studying the dates, times, and usernames! Now that you’ve created a working command-line chatbot, you’ll learn how to train it so you can have slightly more interesting conversations.

Once the bot is ready, we start asking the questions that we taught the chatbot to answer. As usual, there are not that many scenarios to be checked so we can use manual testing. Testing helps to determine whether your AI NLP chatbot works properly.

These rules trigger different outputs based on which conditions are being met and which are not. ‍Currently, every NLG system relies on narrative design – also called conversation design – to produce that output. This narrative design is guided by rules known as “conditional logic”. To nail the NLU is more important than making the bot sound 110% human with impeccable NLG. One of the best things about NLP is that it’s probably the easiest part of AI to explain to non-technical people.

Join our course to learn the fundamentals of NLP and its role in creating chatbots. Gain hands-on experience building chatbots using popular NLP libraries like NLTK. Explore different types of chatbots, including rule-based, retrieval-based, and generative models.

The main package that we will be using in our code here is the Transformers package provided by HuggingFace. This tool is popular amongst developers as it provides tools that are pre-trained and ready to work with a variety of NLP tasks. In the code below, we have specifically used the DialogGPT trained and created by Microsoft based on millions of conversations metadialog.com and ongoing chats on the Reddit platform in a given interval of time. Next, our AI needs to be able to respond to the audio signals that you gave to it. Now, it must process it and come up with suitable responses and be able to give output or response to the human speech interaction. This method ensures that the chatbot will be activated by speaking its name.

Creating the Chatbot

To improve its responses, try to edit your intents.json here and add more instances of intents and responses in it. Just like every other recipe starts with a list of Ingredients, we will also proceed in a similar fashion. So, here you go with the ingredients needed for the python chatbot tutorial. Consider an input vector that has been passed to the network and say, we know that it belongs to class A. Now, since we can only compute errors at the output, we have to propagate this error backward to learn the correct set of weights and biases.
