The AI Chatbot Handbook How to Build an AI Chatbot with Redis, Python, and GPT

It becomes easier for the users to make chatbots using the ChatterBot library with more accurate responses. Finally, in line 13, you call .get_response() on the ChatBot instance that you created earlier and pass it the user input that you collected in line 9 and assigned to query. Running these commands in your terminal application installs ChatterBot and its dependencies into a new Python virtual environment. If you’re comfortable with these concepts, then you’ll probably be comfortable writing the code for this tutorial. If you don’t have all of the prerequisite knowledge before starting this tutorial, that’s okay! You can always stop and review the resources linked here if you get stuck.

You can imagine that training your chatbot with more input data, particularly more relevant data, will produce better results. All of this data would interfere with the output of your chatbot and would certainly make it sound much less conversational. Once you’ve clicked on Export chat, you need to decide whether or not to include media, such as photos or audio messages.

The choice ultimately depends on your chatbot’s purpose, the complexity of tasks it needs to perform, and the resources at your disposal. If you’re a small company, this allows you to scale your customer service operations without growing beyond your budget. You can make your startup work with a lean team until you secure more capital to grow.

You can also check Redis Insight to see your chat data stored with the token as a JSON key and the data as a value. 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. 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.

Creating a function that analyses user input and uses the chatbot’s knowledge store to produce appropriate responses will be necessary. In the Chatbot responses step, we saw that the chatbot has answers to specific questions. And since we are using dictionaries, if the question is not exactly the same, the chatbot will not return the response for the question we tried to ask. Sometimes, we might forget the question mark, or a letter in the sentence and the list can go on. In this relation function, we are checking the question and trying to find the key terms that might help us to understand the question. Finally, we need to update the main function to send the message data to the GPT model, and update the input with the last 4 messages sent between the client and the model.

Maybe at the time this was a very science-fictiony concept, given that AI back then wasn’t advanced enough to become a surrogate human, but now? I fear that people will give up on finding love (or even social interaction) among humans and seek it out in the digital realm. I won’t tell you what it means, but just search up the definition of the term waifu and just cringe. Go to the address shown in the output, and you will get the app with the chatbot in the browser. A JSON file by the name ‘intents.json’, which will contain all the necessary text that is required to build our chatbot. According to a Uberall report, 80 % of customers have had a positive experience using a chatbot.

It’s recommended that you use a new Python virtual environment in order to do this. In this guide, we’re going to look at how you can build your very own chatbot in Python, step-by-step. We initialise the chatbot by creating an instance of it and giving it a name. Here, we call it, ‘MedBot’, since our goal is to make this chatbot work for an ENT clinic’s website. This section will shed light on some of these challenges and offer potential solutions to help you navigate your chatbot development journey. Understanding the types of chatbots and their uses helps you determine the best fit for your needs.

This took a few minutes and required that I plug into a power source for my computer. Python plays a crucial role in this process with its easy syntax, abundance of libraries, and its ability to integrate with web applications and various APIs. With this comprehensive guide, I’ll take you on a journey to transform you from an AI enthusiast into a skilled creator of AI-powered conversational interfaces.

ChatterBot Library In Python

Since this is a publicly available endpoint, we won’t need to go into details about JWTs and authentication. Next create an environment file by running touch .env in the terminal. We will define our app variables and secret variables within the .env file. GPT-J-6B is a generative language model which was trained with 6 Billion parameters and performs closely with OpenAI’s GPT-3 on some tasks.

Simplilearn’s Python Training will help you learn in-demand skills such as deep learning, reinforcement learning, NLP, computer vision, generative AI, explainable AI, and many more. To get started with chatbot development, you’ll need to set up your Python environment. Ensure you have Python installed, and then install the necessary libraries. A great next step for your chatbot to become better at handling inputs is to include more and better training data. ChatterBot is a Python library that makes it easy to generate automated

responses to a user’s input. ChatterBot uses a selection of machine learning

algorithms to produce different types of responses.

For this, you could compare the user’s statement with more than one option and find which has the highest semantic similarity. If you’re not interested in houseplants, then pick your own chatbot idea with unique data to use for training. Repeat the process that you learned in this tutorial, but clean and use your own data for training.

The method we’ve outlined here is just one way that you can create a chatbot in Python. There are various other methods you can use, so why not experiment a little and find an approach that suits you. Don’t forget to test your chatbot further if you want to be assured of its functionality, (consider using software test automation to speed the process up). Once your chatbot is trained to your satisfaction, it should be ready to start chatting. Now you can start to play around with your chatbot, communicating with it in order to see how it responds to various queries. The first step is to install the ChatterBot library in your system.

Because your chatbot is only dealing with text, select WITHOUT MEDIA. To start off, you’ll learn how to export data from a WhatsApp chat conversation. 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.

• We’ll also use the requests library to send requests to the Huggingface inference API.
• Building a ChatBot with Python is easier than you may initially think.
• They have all harnessed this fun utility to drive business advantages, from, e.g., the digital commerce sector to healthcare institutions.
• Keeping track of these features will allow us to stay ahead of the game when it comes to creating better applications for our users.
• This logic adapter uses the Levenshtein distance to compare the input string to all statements in the database.

The more data they are exposed to, the better their responses become. These chatbots are suited for complex tasks, but their implementation is more challenging. These chatbots operate based on predetermined rules that they are initially programmed with. They are best for scenarios that require simple query–response conversations.

You have successfully created an intelligent chatbot capable of responding to dynamic user requests. You can try out more examples to discover the full capabilities of the bot. To do this, you can get other API endpoints from OpenWeather and other sources. Another way to extend the chatbot is to make it capable of responding to more user requests.

Now, when we send a GET request to the /refresh_token endpoint with any token, the endpoint will fetch the data from the Redis database. Next, we add some tweaking to the input to make the interaction with the model more conversational by changing the format of the input. For up to 30k tokens, Huggingface provides access to the inference API for free. In the next section, we will focus on communicating with the AI model and handling the data transfer between client, server, worker, and the external API. We can store this JSON data in Redis so we don’t lose the chat history once the connection is lost, because our WebSocket does not store state. Next, to run our newly created Producer, update chat.py and the WebSocket /chat endpoint like below.

You can Get started with Redis Cloud for free here and follow This tutorial to set up a Redis database and Redis Insight, a GUI to interact with Redis. First we need to import chat from src.chat within our main.py file. Then we will include the router by literally calling an include_router method on the initialized FastAPI class and passing chat as the argument. When we send prompts to GPT, we need a way to store the prompts and easily retrieve the response. However, there is still more to making a chatbot fully functional and feel natural. This mostly lies in how you map the current dialogue state to what actions the chatbot is supposed to take — or in short, dialogue management.

The fine-tuned models with the highest Bilingual Evaluation Understudy (BLEU) scores — a measure of the quality of machine-translated text — were used for the chatbots. Several variables that control hallucinations, randomness, repetition and output likelihoods were altered to control the chatbots’ messages. Whether you want build chatbots that follow rules or train generative AI chatbots with deep learning, say hello to your next cutting-edge skill. In today’s digital age, where communication is increasingly driven by artificial intelligence (AI) technologies, building your own chatbot has never been more accessible. The future of chatbot development with Python looks promising, with advancements in AI and NLP paving the way for more intelligent and personalized conversational interfaces.

You can use hybrid chatbots to reduce abandoned carts on your website. When users take too long to complete a purchase, the chatbot can pop up with an incentive. And if users abandon their carts, the chatbot can remind them whenever they revisit your store. Beyond that, the chatbot can work those strange hours, so you don’t need your reps to work around the clock.

By using chatbots to collect vital information, you can quickly qualify your leads to identify ideal prospects who have a higher chance of converting into customers. Chatbots can pick up the slack when your human customer reps are flooded with customer queries. These bots can handle multiple queries simultaneously and work around the clock.

The bot will not answer any questions then, but another function is forward. Classes are code templates used for creating objects, and we’re going to use them to build our chatbot. Now that we’re armed with some background knowledge, it’s time to build our own chatbot. We’ll be using the ChatterBot library to create our Python chatbot, so  ensure you have access to a version of Python that works with your chosen version of ChatterBot. Use Flask to create a web interface for your chatbot, allowing users to interact with it through a browser.

Here are some of the advantages of using chatbots I’ve discovered and how they’re changing the dynamics of customer interaction. This project showcases engaging interactions between two AI chatbots. Setting a low minimum value (for example, 0.1) will cause the chatbot to misinterpret the user by taking statements (like statement 3) as similar to statement 1, which is incorrect. Setting a minimum value that’s too high (like 0.9) will exclude some statements that are actually similar to statement 1, such as statement 2. Here the weather and statement variables contain spaCy tokens as a result of passing each corresponding string to the nlp() function.

Another Function

GPT-J-6B is a generative language model which was trained with 6 Billion parameters and performs closely with OpenAI’s GPT-3 on some tasks. I’ve carefully divided the project into sections to ensure that you can easily select the phase that is important to you in case you do not wish to code the full application. ChatterBot is a Python library designed to respond to user inputs with automated responses. It uses various machine learning (ML) algorithms to generate a variety of responses, allowing developers to build chatbots that can deliver appropriate responses in a variety of scenarios. Using the ChatterBot library and the right strategy, you can create chatbots for consumers that are natural and relevant.

The final else block is to handle the case where the user’s statement’s similarity value does not reach the threshold value. The chatbot will use the OpenWeather API to tell the user what the current weather is in any city of the world, but you can implement your chatbot to handle a use case with another API. 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! The dataset has about 16 instances of intents, each having its own tag, context, patterns, and responses.

This means that they improve over time, becoming able to understand a wider variety of queries, and provide more relevant responses. AI-based chatbots are more adaptive than rule-based chatbots, and so can be deployed in more complex situations. This allows us to provide data in the form of a conversation (statement + response), and the chatbot will train on this data to figure out how to respond accurately to a user’s input. The instance section allows me to create a new chatbot named “ExampleBot.” The trainer will then use basic conversational data in English to train the chatbot. The response code allows you to get a response from the chatbot itself. You’ll write a chatbot() function that compares the user’s statement with a statement that represents checking the weather in a city.

At this point, you can already have fun conversations with your chatbot, even though they may be somewhat nonsensical. Depending on the amount and quality of your training data, your chatbot might already be more or less useful. Your chatbot has increased its range of responses based on the training data that you fed to it.

AI-based chatbots

Next, you’ll create a function to get the current weather in a city from the OpenWeather API. In this section, you will create a script that accepts a city name from the user, queries the OpenWeather API for the current weather in that city, and displays the response. Because the industry-specific chat data in the provided WhatsApp chat export focused on houseplants, Chatpot now has some opinions on houseplant care. It’ll readily share them with you if you ask about it—or really, when you ask about anything.

If you’re going to work with the provided chat history sample, you can skip to the next section, where you’ll clean your chat export. You can foun additiona information about ai customer service and artificial intelligence and NLP. The ChatterBot library comes with some corpora that you can use to train your chatbot. However, at the time of writing, there are some issues if you try to use these resources straight out of the box. In lines 9 to 12, you set up the first training round, where you pass a list of two strings to trainer.train().

You want to extract the name of the city from the user’s statement. In the next section, you’ll create a script to query the OpenWeather API for the current weather in a city. SpaCy’s language models are pre-trained NLP models that you can use to process statements to extract meaning. You’ll be working with the English language model, so you’ll download that. This tutorial assumes you are already familiar with Python—if you would like to improve your knowledge of Python, check out our How To Code in Python 3 series. This tutorial does not require foreknowledge of natural language processing.

• Try adding some more clean training data and see how accurate you can make it.
• You can make your startup work with a lean team until you secure more capital to grow.
• The more plentiful and high-quality your training data is, the better your chatbot’s responses will be.
• Beyond learning from your automated training, the chatbot will improve over time as it gets more exposure to questions and replies from user interactions.
• This project showcases engaging interactions between two AI chatbots.

The more plentiful and high-quality your training data is, the better your chatbot’s responses will be. We now have smart AI-powered Chatbots employing natural language processing (NLP) to understand and absorb human commands (text and voice). Chatbots have quickly become a standard customer-interaction tool for businesses that have a strong online attendance (SNS and websites). The ChatterBot library combines language corpora, text processing, machine learning algorithms, and data storage and retrieval to allow you to build flexible chatbots. Also, consider the state of your business and the use cases through which you’d deploy a chatbot, whether it’d be a lead generation, e-commerce or customer or employee support chatbot. Operating on basic keyword detection, these kinds of chatbots are relatively easy to train and work well when asked pre-defined questions.

Using cloud storage solutions can provide flexibility and ensure that your chatbot can handle increasing amounts of data as it learns and interacts with users. It’s also essential to plan for future growth and anticipate the storage requirements of your chatbot’s conversations and training data. By leveraging cloud storage, you can easily scale your chatbot’s data storage and ensure reliable access to the information it needs. Python AI chatbots are essentially programs designed to simulate human-like conversation using Natural Language Processing (NLP) and Machine Learning. The design of ChatterBot is such that it allows the bot to be trained in multiple languages. On top of this, the machine learning algorithms make it easier for the bot to improve on its own using the user’s input.

We will use WebSockets to ensure bi-directional communication between the client and server so that we can send responses to the user in real-time. To set up the project structure, create a folder namedfullstack-ai-chatbot. Then create two folders within the project called client and server. The server will hold the code for the backend, while the client will hold the code for the frontend. Its versatility, extensive libraries like NLTK and spaCy for natural language processing, and frameworks like ChatterBot make it an excellent choice. Python’s simplicity, readability, and strong community support contribute to its popularity in developing effective and interactive chatbot applications.

They have all harnessed this fun utility to drive business advantages, from, e.g., the digital commerce sector to healthcare institutions. This is one of the few guided projects where everything is explained clearly. Note that we are using the same hard-coded token to add to the cache Chat GPT and get from the cache, temporarily just to test this out. You can always tune the number of messages in the history you want to extract, but I think 4 messages is a pretty good number for a demo. Now when you try to connect to the /chat endpoint in Postman, you will get a 403 error.

To do so, you can use the “File Browser” feature while you are accessing your cloud desktop. If you’re interested in becoming a project instructor and creating Guided Projects https://chat.openai.com/ to help millions of learners around the world, please apply today at teach.coursera.org. Any competent computer user with basic familiarity with python programming.

In the next section, we will build our chat web server using FastAPI and Python. In addition to all this, you’ll also need to think about the user interface, design and usability of your application, and much more. And now we need to train the bot with the data i have loaded into this script. Now, we have to open the file where the conversations are stored.For this we write the following code. It will select the answer by bot randomly instead of the same act.

This is important if we want to hold context in the conversation. We will not be building or deploying any language models on Hugginface. Instead, we’ll focus on using Huggingface’s accelerated inference API to connect to pre-trained models. We are adding the create_rejson_connection method to connect to Redis with the rejson Client. This gives us the methods to create and manipulate JSON data in Redis, which are not available with aioredis.

It’s rare that input data comes exactly in the form that you need it, so you’ll clean the chat export data to get it into a useful input format. This process will show you some tools you can use for data cleaning, which may help you prepare other input data to feed to your chatbot. Fine-tuning builds upon a model’s training by python chatbot feeding it additional words and data in order to steer the responses it produces. Chat LMSys is known for its chatbot arena leaderboard, but it can also be used as a chatbot and AI playground. Nobody likes to be alone always, but sometimes loneliness could be a better medicine to hunch the thirst for a peaceful environment.
