Building a Chatbot using Chatterbot in Python
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. The significance of Python AI chatbots is paramount, especially in today’s digital age. They are changing the dynamics of customer interaction by being available around the clock, handling multiple customer queries simultaneously, and providing instant responses. This not only elevates the user experience but also gives businesses a tool to scale their customer service without exponentially increasing their costs. To create your own AI chat bot with the ChatGPT API, you can use any
programming language that supports HTTP requests and JSON parsing.
- It lets the programmers be confident about their entire chatbot creation journey.
- In this tutorial, we’ll be building a simple chatbot using Python and the Natural Language Toolkit (NLTK) library.
- NLP, or Natural Language Processing, stands for teaching machines to understand human speech and spoken words.
- Your chatbot has increased its range of responses based on the training data that you fed to it.
After we are done setting up the flask app, we need to add two more directories static and templates for HTML and CSS files. With increasing advancements, there also comes a point where it becomes fairly difficult to work with the chatbots. To extract the city name, you get all the named entities in the user’s statement and check which of them is a geopolitical entity (country, state, city). If it is, then you save the name of the entity (its text) in a variable called city. Here the weather and statement variables contain spaCy tokens as a result of passing each corresponding string to the nlp() function. Your chatbot is now ready to engage in basic communication, and solve some maths problems.
ChatterBot: Build a Chatbot With Python
With the rise in the use of machine learning in recent years, a new approach to building chatbots has emerged. Using artificial intelligence, it has become possible to create extremely intuitive and precise chatbots tailored to specific purposes. After all of the functions that we have added to our chatbot, it can now use speech recognition techniques to respond to speech cues and reply with predetermined responses. However, our chatbot is still not very intelligent in terms of responding to anything that is not predetermined or preset. Scripted chatbots are chatbots that operate based on pre-determined scripts stored in their library. When a user inputs a query, or in the case of chatbots with speech-to-text conversion modules, speaks a query, the chatbot replies according to the predefined script within its library.
Then you can improve your chatbot’s results by feeding the bot with your own conversations. A chatbot is a computer program that holds an automated conversation with a human via text or speech. In other words, a chatbot simulates a human-like conversation in order to perform a specific task for an end user.

Today, we have a number of successful examples which understand myriad languages and respond in the correct dialect and language as the human interacting with it. Most of this success is through the SpeechRecognition library. Python is a popular choice for creating various types of bots due to its versatility and abundant libraries. Whether it’s chatbots, web crawlers, or automation bots, Python’s simplicity, extensive ecosystem, and NLP tools make it well-suited for developing effective and efficient bots.
You have created a chatbot that is intelligent enough to respond to a user’s statement—even when the user phrases their statement in different ways. The chatbot uses the OpenWeather API to get the current weather in a city specified by the user. Next you’ll be introducing the spaCy similarity() method to your chatbot() function. The similarity() method computes the semantic similarity of two statements as a value between 0 and 1, where a higher number means a greater similarity.
The updated and formatted dictionary is stored in keywords_dict. The intent is the key and the string of keywords is the value of the dictionary. Here, we first defined a list of words list_words that we will be using as our keywords.
Step-3: Reading the JSON file
Inside the function, we construct the URL for the OpenWeather API. The URL returns the weather information of the city in JSON format. After this, we make a GET request using requests.get() function to the API endpoint and we store the result in the response variable. After this, the result of the GET request is converted to a Python dictionary using response.json(). And that is how you build your own AI chatbot with the ChatGPT API.
If a server is already running, press “Ctrl + C” to stop it. You will have to restart the server after every change you make to the “app.py” file. Make sure to replace the “Your API key” text with your own API key generated above. Next, click on your profile in the top-right corner and select “View API keys” from the drop-down menu.

Humans take years to conquer these challenges when learning a new language from scratch. In human speech, there are various errors, differences, and unique intonations. NLP technology empowers machines to rapidly understand, process, and respond to large volumes of text in real-time. You’ve likely encountered NLP in voice-guided GPS apps, virtual assistants, speech-to-text note creation apps, and other chatbots that offer app support in your everyday life. In the business world, NLP is instrumental in streamlining processes, monitoring employee productivity, and enhancing sales and after-sales efficiency. You’ll need the ability to interpret natural language and some fundamental programming knowledge to learn how to create chatbots.
If those two statements execute without any errors, then you have spaCy installed. Start learning immediately instead of fiddling with SDKs and IDEs. The average video tutorial is spoken at 150 words per minute, while you can read at 250. Practice as you learn with live code environments inside your browser.
And to learn about all the cool things you can do with ChatGPT, go follow our curated article. Finally, if you are facing any issues, let us know in the comment section below. To restart the AI chatbot server, simply copy the path of the file again and run the below command again (similar to step #6). Keep in mind, the local URL will be the same, but the public URL will change after every server restart. The guide is meant for general users, and the instructions are clearly explained with examples.

In lines 9 to 12, you set up the first training round, where you pass a list of two strings to trainer.train(). Using .train() injects entries into your database to build upon the graph structure that ChatterBot uses to choose possible replies. In the previous step, you built a chatbot that you could interact with from your command line. The chatbot started from a clean slate and wasn’t very interesting to talk to. The call to .get_response() in the final line of the short script is the only interaction with your chatbot.

Large Language Models
After creating the pairs of rules above, we define the chatbot using the code below. The code is simple and prints a message whenever the function is invoked. If you’re looking to build a chatbot using Python code, there are a few ways you can go about it. One way is to use a library such as ChatterBot, which makes it easy to create and train your own chatbot.
This is an extra function that I’ve added after testing the chatbot with my crazy questions. So, if you want to understand the difference, try the chatbot with and without this function. And one good part about writing the whole chatbot from scratch is that we can add our personal touches to it. We are defining the function that will pick a response by passing in the user’s message.
- Natural Language Processing, often abbreviated as NLP, is the cornerstone of any intelligent chatbot.
- Whether you want build chatbots that follow rules or train generative AI chatbots with deep learning, say hello to your next cutting-edge skill.
- ” It can also tell you jokes, give you weather updates, or provide support information.
- Make sure to replace the “Your API key” text with your own API key generated above.
RNNs process data sequentially, one word for input and one word for the output. In the case of processing long sentences, RNNs work too slowly and can fail at handling long texts. As you can see the chatbot responded to ‘My name is Akshay’ because we have trained it. It returned None when we used the sentence or rule on which it is not trained. So we need to train our chatbot on each and everything we need it to answer.
