You can also do it by specifying the lists of strings that can be utilized for training the Python chatbot, and choosing the best match for each argument. The process of building a chatbot in Python begins with the installation of the ChatterBot library in the system. For best results, make use of the latest Python virtual environment. Let us consider the following example of training the Python chatbot with a corpus of data given by the bot itself. In the above snippet of code, we have imported two classes - ChatBot from chatterbot and ListTrainer from chatterbot.trainers. The second step in the Python chatbot development procedure is to import the required classes.

Unfortunately, many people still don’t know about the benefits of this fantastic practice or how accessible it is. It is a conversational web application to educate people on yoga’s awesomeness. Programmers develop chatbots using several different methods ranging from beginner to advanced. In this article, we define chatbots and will program our own version using Python, NLTK, and PyTorch. It’s clear that ChatGPT is powerful and an excellent example of the technical evolution of machine-learning chatbots, but what exactly can you do with it? Keep in mind the platform still has a ways to go before it can execute these applications to the same level as humans.

This not only elevates the user experience but also gives businesses a tool to scale their customer service without exponentially increasing their costs. Then it generates a pickle file in order to store the objects of Python that are utilized to predict the responses of the bot.

What is rule-based chatbot vs AI based chatbot?

AI chatbots, in contrast, are used for more complicated cases to fully resolve customers' issues. Also, rule-based bots are limited by typos or wrong keywords that people might use. This is why rule-based chatbots require more data for automated customer service training.

Rule-based chatbots can have difficulty handling intricate suggestions—a tricky drawback to resolve. But with conversational AI, there are very few unmanageable drawbacks. And compared to rule-based chatbots, conversation AI can better implement a customer-focused approach.

This lays down the foundation for more complex and customized chatbots, where your imagination is the limit. Experiment with different training sets, algorithms, and integrations to create a chatbot that fits your unique needs and demands. Moreover, all the user groups should use a chatbot without a need to learn anything.

In the above image, we have created a bow (bag of words) for each sentence. Basically, a bag of words simple representation of each text in a sentence as the bag of its words. Tokenize or Tokenization is used to split a large sample of text or sentences into words. In the below image, I have shown the sample from each list we have created.

We will create a method that takes in user input, finds the cosine similarity of the user input and compares it with the sentences in the corpus. Rather, we will develop a very simple rule-based chatbot capable of answering user queries regarding the sport of Tennis. But before we begin actual coding, let's first briefly discuss what chatbots are and how they are used.
