Create a ChatBot with Python and ChatterBot: Step By Step

The bot will be able to respond to greetings (Hi, Hello etc.) and will be able to answer questions about the bank’s hours of operation. It is an open-source collection of libraries that is widely used for building NLP programs. It has several libraries for performing tasks like stemming, lemmatization, tokenization, and stop word removal.

To follow along, please add the following function as shown below. This method ensures that the chatbot will be activated by speaking its name. When you say “Hey Dev” or “Hello Dev” the bot will become active.

ChatterBot comes with a List Trainer which provides a few conversation samples that can help in training your bot. As these commands are run in your terminal application, ChatterBot is installed along with its dependencies in a new Python virtual environment. Now, recall from your high school classes that a computer only understands numbers. Therefore, if we want to apply a neural network algorithm on the text, it is important that we convert it to numbers first. And one way to achieve this is using the Bag-of-words (BoW) model.

StudentAI is an AI chatbot app that uses OpenAI’s large language model to help students learn more effectively. StudentAI can answer questions, provide explanations, and even generate creative content. This makes it a powerful tool for students of all ages and levels of learning. Now, it’s time to move on to the second step of the algorithm that is used in building this chatbot application project. Python Chatbot Project Machine Learning-Explore chatbot implementation steps in detail to learn how to build a chatbot in python from scratch. Yes, because of its simplicity, extensive library and ability to process languages, Python has become the preferred language for building chatbots.

Step 6: Keep interacting with the user until they say “bye”.

Let’s have a quick recap as to what we have achieved with our chat system. The chat client creates a token for each chat session with a client. This token is used to identify each client, and each message sent by clients connected to or web server is queued in a Redis channel (message_chanel), identified by the token. Next, we want to create a consumer and update our worker.main.py to connect to the message queue. We want it to pull the token data in real-time, as we are currently hard-coding the tokens and message inputs.

Note that saving

the brain file does not save all the session values. When you start to have a lot of AIML files, it can take a long time to learn. After the bot learns all the AIML files

it can save its brain directly to a file which will drastically speed up load times

on subsequent runs. It can be fun to write your own AIML files, but it can be a lot of work.

If it does then we return the token, which means that the socket connection is valid. We can store this JSON data in Redis so we don’t lose the chat history once the connection is lost, because our WebSocket does not store state. Next open up a new terminal, cd into the worker folder, and create and activate a new Python virtual environment similar to what we did in part 1. Imagine a scenario where the web server also creates the request to the third-party service. Now when you try to connect to the /chat endpoint in Postman, you will get a 403 error.

Now, you will create a chatbot to interact with a user in natural language using the weather_bot.py script. You’ve learned how to make your first AI in Python by making a chatbot that chooses random responses from a list and keeps track of keywords and responses it learns using lists. NLTK is a leading platform for building NLP programs to work with human language data. This library provides a practical introduction to programming for language processing. Do you want to take your customer interactions to the next level? With the [newline]power of Artificial Intelligence development, you can now make your own

chatbot.

Now, we set top_k to 100 to sample from the top 100 words sorted descendingly by probability. In the below image, I have used the Tkinter in python to create a GUI. Please note that if you are using Google Colab then Tkinter will not work. You have to use your local system/PC to use the Tkinter library. In the above image, we have created a bow (bag of words) for each sentence.

This blog was a hands-on introduction to building a very simple rule-based chatbot in python. You can easily expand the functionality of this chatbot by adding more keywords, intents and responses. The four steps underlined in this article are essential to creating AI-assisted chatbots. Thanks to NLP, it has become possible to build AI chatbots that understand natural language and simulate near-human-like conversation. They also enhance customer satisfaction by delivering more customized responses. Professors from Stanford University are instructing this course.
