How To Make AI Chatbot In Python Using NLP NLTK In 2023

Python has become a leading choice for building AI chatbots owing to its ease of use, simplicity, and vast array of frameworks. For computers, understanding numbers is easier than understanding words and speech. When the first few speech recognition systems were being created, IBM Shoebox was the first to get decent success with understanding and responding to a select few English words. Today, we have a number of successful examples which understand myriad languages and respond in the correct dialect and language as the human interacting with it. In the above, we have created two functions, “greet_res()” to greet the user based on bot_greet and usr_greet lists and “send_msz()” to send the message to the user.

Lemmatization is grouping together the inflected forms of words into one word. For example, the root word or lemmatized word for trouble, troubling, troubled, and trouble is trouble. Using the same concept, we have a total of 128 unique root words present in our training dataset.

We covered several steps in the whole article for creating a chatbot with ChatGPT API using Python which would definitely help you in successfully achieving the chatbot creation in Gradio. There are countless uses of Chat GPT of which some we are aware and some we aren’t. Here we are going to see the steps to use OpenAI in Python with Gradio to create a chatbot. In the below image, I have used the Tkinter in python to create a GUI.

To send messages between the client and server in real-time, we need to open a socket connection. This is because an HTTP connection will not be sufficient to ensure real-time bi-directional communication between the client and the server. One of the best ways to learn how to develop full stack applications is to build projects that cover the end-to-end development process.

Python AI: A Beginner’s Guide

After you’ve completed that setup, your deployed chatbot can keep improving based on submitted user responses from all over the world. You can imagine that training your chatbot with more input data, particularly more relevant data, will produce better results. Depending on your input data, this may or may not be exactly what you want. For the provided WhatsApp chat export data, this isn’t ideal because not every line represents a question followed by an answer. To train your chatbot to respond to industry-relevant questions, you’ll probably need to work with custom data, for example from existing support requests or chat logs from your company. The ChatterBot library comes with some corpora that you can use to train your chatbot.

NLP combines computational linguistics, which involves rule-based modeling of human language, with intelligent algorithms like statistical, machine, and deep learning algorithms. Together, these technologies create the smart voice assistants and chatbots we use daily. In the realm of chatbots, NLP comes into play to enable bots to understand and respond to user queries in human language. Well, Python, with its extensive array of libraries like NLTK (Natural Language Toolkit), SpaCy, and TextBlob, makes NLP tasks much more manageable. These libraries contain packages to perform tasks from basic text processing to more complex language understanding tasks.

Also, create a folder named redis and add a new file named config.py. In the next part of this tutorial, we will focus on handling the state of our application and passing data between client and server. In the src root, create a new folder named socket and add a file named connection.py. In this file, we will define the class that controls the connections to our WebSockets, and all the helper methods to connect and disconnect.

NLP technologies are constantly evolving to create the best tech to help machines understand these differences and nuances better. In this article, we have successfully discussed Chatbots and their types and created a semi-rule-based chatbot by cleaning the Corpus data, pre-processing, and training the Sequential NN model. We have discussed tokenization, a bag of words, and lemmatization, and also created a Python Tkinter-based GUI for our chatbot.

This will help you determine if the user is trying to check the weather or not. In addition to this, Python also has a more sophisticated set of machine-learning capabilities with an advantage of choosing from different rich interfaces and documentation. Without this flexibility, the chatbot’s application and functionality will be widely constrained.

Also, each actual message starts with metadata that includes a date, a time, and the username of the message sender. 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! Moving forward, you’ll work through the steps of converting chat data from a WhatsApp conversation into a format that you can use to train your chatbot. If your own resource is WhatsApp conversation data, then you can use these steps directly.
