Designing A ChatBot Using Python: A Modified Approach by Abhijit Roy

Chatbots are one of the top points in the digital strategies of companies worldwide. However, in 2020 brands were pushed to connect with and serve their customers online due to the pandemic. As a result, the global chatbot market value will steadily increase over the next several years. A Statista report projects chatbot market revenues to hit $83.4 million in 2021 and $454.8 million by 2027. These chatbots utilize various Machine Learning (ML), Deep Learning (DL), and Artificial Intelligence (AI) algorithms to remember past conversations and self-improve with time. Artificial intelligence has brought numerous advancements to modern businesses.

The next step is to iterate through the yoga data in the JSON file. Then for every tag in our file, we perform tokenization on the related patterns data. We also add the tag and token pairing to the list for future xy training data. Articles are published daily about managing your stress levels more relaxed life. One of the main recommendations to reduce your stress is to practice yoga.

Python Programs

To set the storage adapter, we will assign it to the import path of the storage we’d like to use. In this case, it is SQL Storage Adapter that helps to connect chatbot to databases in SQL. It uses Natural Language Processing (NLP) algorithms to form answers based on the detected keywords.

Businesses use chatbots to ensure customer support and assistance outside working hours. The answers of an advanced chatbot can be so contextual and personalized that no human aid is needed to solve most customer requests. This technology allows businesses to free their human staff to resolve more complex issues. A chatbot is a piece of software or a computer program that mimics human interaction via voice or text exchanges.

Building your own Rule-Based Conversational Chatbot Python Implementation

You can see why this type of chatbot is called a rule-based chatbot. There are plenty of rules to follow and if we want to add more functionalities to the chatbot, we will have to add more rules. This very simple rule based chatbot will work by searching for specific keywords in inputs given by a user. The keywords will be used to understand what action the user wants to take (user’s intent). The above execution of the program tells us that we have successfully created a chatbot in Python using the chatterbot library.

A rule-based system is a system that applies human-defined parameters and executes them based on specific commands. Rule-based chatbots offer predetermined answers to a set of already inputted questions. Natural language processing plays a significant role in building rule-based chatbots. NLP technology is beneficial for the bots to understand customer requests and break down the complexity of human language. Most online visitors are actively looking for a product to buy, so a website that resolves customers’ problems quickly will generate more revenue.

How to Create a Chatbot with ChatGPT

We define a variable called ignore_words to house any tokens we don’t want to include in our stemming task. The variable reassigns during each operation, including sorting and removing duplicate words. The stem_and_lower() function we write invokes NLTK’s PorterStemmer package to stem each returned tokenized word. The method we write here returns an array of tokens using NLTK’s word_tokenize package. PyTorch has different versioning requirements based on your type of machine environment. Check out their official documentation for more information on installing the right one.

  • That’s why AI bots are preferred in businesses that demand human-like responses from bots.
  • After saving the Pytorch tensor and YogaChatDataset to variables, we also define variables for loss and optimization of our model.
  • This is where tokenizing supports text data – it converts the large text dataset into smaller, readable chunks (such as words).

Armed with sufficient knowledge and appropriate hardware, companies can now create fully independent open-source chatbots boasting state-of-the-art capabilities. These relatively “old” approaches are more difficult to configure and implement, they also produce less wow effect on end-users compared to ChatGPT. Since GPT 3.5 and GPT 4 models are proprietary, it’s impressive that HuggingChat offers a free chatbot platform based on the open-source Llama2 model. We’ll also briefly introduce you to n8n – an extendable source-available workflow automation tool.

What are the different types of chatbots in Python?

There are generally two types of bots: Artificial Intelligence (AI) and Machine Learning (ML) chatbots. Rule-based chatbot: A rule-based bot can only comprehend a limited range of choices that it has been programmed with.
