Creating a Simple Rule-Based Chatbot with Python by Cornellius Yudha Wijaya Geek Culture

Rule-Based vs AI Chatbot: Which One is Better?

The catch with GPT-based AI chatbots is their reliance on cloud-based providers such as the OpenAI GPT API and Claude service among others. A rule-based chatbot works with the data set that you induce in the bot. With the set of rules in the rule-based chatbot, you can manipulate the conversation. Rule-based chatbots are also known as flow bots that provide branch-like questions.

We now create a class with initialized attributes of the number of training samples, the training samples themselves, and the sample tags. We define empty lists to hold our future tokenized words, the tags from our JSON file, and our eventual split training data. The code begins with importing the necessary Python libraries and the methods we created in our other Python scripts. Our chatbot, unfortunately, will not understand the words as strings like humans do. We need to convert the pattern strings to numbers that the neural network can understand. A bag of words has the same size as an array with all the words combined.

AI chatbots are expensive to build compared to the other bots, to mimic a human conversation it takes a lot of time to build a bot. However, companies now have packages starting at $495 a month that include building and training conversation AI chatbots for e-commerce, support, and lead generation. Conversing with the rule-based chatbots might be frustrating for customers since rule-based bots don’t have Artificial intelligence behind them to understand every question.

In this section, we’ll walk you through a simple step-by-step guide to creating your first Python AI chatbot. We’ll be using the ChatterBot library in Python, which makes building AI-based chatbots a breeze. 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.

This will be used to find the similarity between words entered by the user and the words in the corpus. To generate a response from our bot for input questions, the concept of document similarity will be used. Or similarly, depending on your business, you need to decide whether to choose a virtual assistant or a sales bot. The latter gathers data and generates sales, while the former is best for answering questions or scheduling bookings. They might be more complex and difficult to train, but they can link customers’ previous questions to the new ones and makes personalized and smoother responses. Let’s have a quick review of both rule-based chatbots and AI chatbots.

This tutorial doesn’t use forks to get started, so using PyPI’s pinned version will suffice. Step one provides instructions for installing self-supervised learning ChatterBot; step 2 details how it should be set up without training (step 1). Eventually, the untrained vocabulary of an unable chatbot may prove limited, as shown herein. The first and foremost thing before starting to build a chatbot is to understand the architecture. For example, how chatbots communicate with the users and model to provide an optimized output.

The program picks the most appropriate response from the nearest statement that matches the input and then delivers a response from the already known choice of statements and responses. Over time, as the chatbot indulges in more communications, the precision of reply progresses. Pytorch provides its own data primitive type called torch.utils.data.DataLoader that wraps an iterable around our dataset. This method uses their API to classify training and label data further. After saving the Pytorch tensor and YogaChatDataset to variables, we also define variables for loss and optimization of our model. We use PyTorch’s CrossEntropyLoss() method to calculate the difference between the probability distribution of the given set of variables in our dataset.

The code for training our yoga chatbot is in the file chatbot_training.py. In the structure of our app, we have a file called nlp_uitls.py that houses the NLP tasks performed on the yoga JSON file. These functions are created here and imported into our main yoga chatbot code. They are able to support as many languages as needed within a single workflow. If you utilize Telegram, the user interface language is automatically recognized – a boon for businesses catering to multiple geographical regions.

The chatbot will look something like this, which will have a textbox where we can give the user input, and the bot will generate a response for that statement. If you need help in how to build a chatbot into your system, it’s a wise choice to choose an IT outsourcing company like TECHVIFY Software to support you. Your process will be more streamlined and cost-efficient, and you will still have an answer that perfectly fits your business. The chatbot should remember user preferences, history, and context to deliver tailored responses and recommendations. You may quickly develop a chatbot using Chat GPT by following the instructions in this guide. By the end, you’ll have an AI chatbot that is fully operational and ready to improve customer service, automate processes, or efficiently assist users.

At the same time, a rule-based chatbot is simple to implement but has limited scope and no self-learning ability. Statistics show that most business owners prefer a bit powered by Artificial Intelligence. If you ever wish to make your own AI bot, get assistance from AirDroid’s ChatInsight. This powerful bot builder can help you boost sales, increase revenue, and improve customer delivery. Generally, rule-based chatbots are easy to build, maintain, and operate.

PyTorch, NLTK and other dependencies

We will import ‘ListTrainer,’ create its object by passing the ‘Chatbot’ object, and then call the ‘train()’ method by passing a set of sentences. It utilizes a decision tree hierarchy presented to a user as a list of buttons. Using the menu, customers can select the option they need and get the proper instructions to solve their problem or get the required information. This type of chatbots is widely used to answer FAQs, which make up about 80% of all support requests. Rule-based chatbots are well-suited for handling routine and straightforward interactions, while AI-based chatbots provide a more personalized and engaging user experience. They can handle a wider range of queries, making them suitable for businesses with diverse customer interactions.
