ChatGPT and the Evolution of AI: From Rule-based Systems to Advanced Machine Learning

The chatbots are programs that could simulate the conversation of a human through voice or text interactions. These bots are increasingly being used in both B2B and B2C (Business-to-Business & Business-to-Consumer) to handle various look-up tasks. Chatbots are conversational agents that engage in different types of conversations with humans. Chatbots are finding their place in different strata of life ranging from personal assistant to ticket reservation systems and physiological therapists.

It is important to mention that the idea of this article is not to develop a perfect chatbot but to explain the working principle of rule-based chatbots. Using Cosine-Similarity, we would create a chatbot that answers the queries by measuring the similarities between the query and the corpus we developed. In a business environment, a chatbot could be required to have a lot more intent depending on the tasks it is supposed to undertake. The chatbot will automatically pull their synonyms and add them to the keywords dictionary. You can also edit list_syn directly if you want to add specific words or phrases that you know your users will use.

Top Applications of Chatbots

These rules are the basis for the types of problems the chatbot is familiar with and can deliver solutions for. Some of the best chatbots available include Microsoft XiaoIce, Google Meena, and OpenAI’s GPT 3. These chatbots employ cutting-edge artificial intelligence techniques that mimic human responses. Python is one of the best languages for building chatbots because of its ease of use, large libraries and high community support. Once the dependence has been established, we can build and train our chatbot.

Let’s start by exploring types of chatbots based on their technical logic and architecture. So, don’t be afraid to experiment, iterate, and learn along the way. Make your chatbot more specific by training it with a list of your custom responses.

How To Make An AI-Based Chatbot Using Python?

An AI bot needs proper training or can misinterpret conversations and generate inaccurate results. But after getting more user input with time, they can solve complicated situations without human intervention. As the name indicates, an AI chatbot is powered by Artificial Intelligence. Compared to a rule-based chatbot in Python, they rely on machine learning models to understand the real meaning of a customer query and provide solutions. One of the advantages of rule-based chatbots is that they always give accurate results.

The objective of the ‘chatterbot.logic.MathematicalEvaluation’ command helps the bot to solve math problems. The ‘chatterbot.logic.BestMatch’ command enables the bot to evaluate the best match from the list of available responses. We can use the get_response() function in order to interact with the Python chatbot. Let us consider the following execution of the program to understand it. In the above snippet of code, we have created an instance of the ListTrainer class and used the for-loop to iterate through each item present in the lists of responses.

The right dependencies need to be established before we can create a chatbot. With Pip, the Chatbot Python package manager, we can install ChatterBot. The end goal for commercial implementation of any technology is bringing money and saving money.

The following video shows an end-to-end interaction with the designed bot. There could be multiple paths using which we can interact and evaluate the built text bot. The following videos show an end-to-end interaction with the designed bot.

For instance, a company selling products online requires a chatbot that should interact with customers intuitively, and it should be able to handle complex queries. These chatbots in the FAQs section of almost all the airlines, 5-start hotels, etc., present a list of pre-set options or questions. It is hardly surprising that Chatbot is a “Buzzword” in the business world. Many business owners plan to develop a website chatbot to improve customer delivery and boost sales.

The super() method is a built-in Python method that returns a substitute object that can call methods of the base class, Yoga_Neural_Network(). PyTorch’s nn.Linear() module applies the linear activation function to the desired code. We then have to use the ReLU() activation function, a class in PyTorch that helps convert linear functions back to non-linear. The NLP tasks we will perform are tokenization, stemming, and transferring the text into a bag of words for the chatbot neural network to understand. If NLTK is not already installed in your environment, use the pip command to download. The platform is based on a machine learning model, which means it can continuously learn and improve over time.

Rule-based chatbots are structured as a dialog tree and often use regular expressions to match a user’s input to human-like responses. The aim is to simulate the back-and-forth of a real-life conversation, often in a specific context, like telling the user what the weather is like outside. In chatbot design, rule-based chatbots are closed-domain, also called dialog agents, because they are limited to conversations on a specific subject. Once the response is generated, the user input is removed from the collection of sentences since we do not want the user input to be part of the corpus.

We will use a ChatterBot library that features ML-based algorithms to generate meaningful responses to users’ requests. Go through these steps to develop a Python-based chatbot from scratch. Let’s look at a simple example of a chatbot that the Dataсamp training platform describes in its tutorials.

First, we implement tokenization with the tokenize_yoga_data() method. You can find the complete code for this project here on my GitHub profile. For small tasks, such as research and organizing data, ChatGPT is a valuable tool that’s comparable to any virtual human assistant. However, as yet, the platform is unable to directly access and interact with external platforms such as WordPress without proper integration from a developer.
