Creating a ChatBot using ChatterBot Python

build chatbot using python

To build our chatbot, we’ll be using Python, so make sure you have Python installed on your system. You can download and install Python from the official website. Additionally, we’ll be using the re (regular expression) module, which comes with Python by default. In the exciting world of technology, we’re constantly uncovering fresh ways to make our lives easier and more efficient. One remarkable advancement that stands out is the emergence of chatbots – these are clever computer programs designed to interact with us using natural informal language. Here the weather and statement variables contain spaCy tokens as a result of passing each corresponding string to the nlp() function.

With Pip, the Chatbot Python package manager, we can install ChatterBot. Depending on your input data, this may or may not be exactly what you want. For the provided WhatsApp chat export data, this isn’t ideal because not every line represents a question followed by an answer.

Python for Data Science

To begin with this project, it’s crucial to have a basic understanding of Python programming and some knowledge of regular expressions and manipulating strings. They’re here to answer your questions, explain tricky concepts, and even guide you through your homework. Learning becomes more interactive and personalized with their help. They’re like those friendly store assistants who help you find the perfect outfit or gadget, answer questions about products, and even suggest items based on your style. A chatbot is an artificial intelligence that simulates a conversation with a user through apps or messaging.

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. ChatterBot makes it easy to create software that engages in conversation. Every time a chatbot gets the input from the user, it saves the input and the response which helps the chatbot with no initial knowledge to evolve using the collected responses. The design of ChatterBot is such that it allows the bot to be trained in multiple languages.

The roles in OpenAI messages.

In this article, I’ve provided you with a basic guide to get started. Once you have your chatbot up and running, it’ll be able to handle simple tasks and conversations. If you want to take your chatbot to the next level, you can consider adding more features or connecting it to other services. In this simple guide, I’ll walk you through the process of building a basic chatbot using Python code.

  • A chatbot is an artificial intelligence based tool built to converse with humans in their native language.
  • When you understand the basics of the ChatterBot library, you can build and train a self-learning chatbot with just a few lines of Python code.
  • To begin with this project, it’s crucial to have a basic understanding of Python programming and some knowledge of regular expressions and manipulating strings.

Now, you will create a chatbot to interact with a user in natural language using the script. This series is designed to teach you how to create simple deep learning chatbot using python, tensorflow and nltk. The chatbot we design will be used for a specific purpose like answering questions about a business. Within Chatterbot, training becomes an easy step that comes down to providing a conversation into the chatbot database.

What is ChatterBot Library?

Before we start with the tutorial, we need to understand the different types of chatbots and how they work. You can create Chatbot using Python with the help of its NLTK library. Python Tkinter module is beneficial while developing this application. You can design a simple GUI of Chatbot using this module to create a text box and button to submit the user queries. Once the queries are submitted, you can create a function that allows the program to understand the user’s intent and respond to them with the most appropriate solution.

After the statement is passed into the loop, the chatbot will output the proper response from the database. ‘Bye’ or ‘bye’ statements will end the loop and stop the conversation. When we think of chatbots, we might visualize advanced AI assistants like Alexa or Siri.

Firstly, we import the requests library so that we can make the HTTP requests and work with them. In the next line, you must replace the your_api_key with the API key generated for your account. Now it’s time to import the necessary libraries and report the value of the key that we just obtained from OpenAI.

More complex rules can be added to further strengthen the chatbot. You have created a simple rule-based chatbot, and the last step is to initiate the conversation. This is done using the code below where the converse() function triggers the conversation. 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. Keep in mind that the chatbot will not be understand all the questions and will not be capable of answering each one. Since its knowledge and training input is limited, you will need to hone it by feeding more training data.

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. Once we have imported our libraries, we’ll need to build up a list of keywords that our chatbot will look for. The more keywords you have, the better your chatbot will perform. The bot will be able to respond to greetings (Hi, Hello etc.) and will be able to answer questions about the bank’s hours of operation. Now that we’re familiar with how chatbots work, we’ll be looking at the libraries that will be used to build our simple Rule-based Chatbot.

You do remember that the user will enter their input in string format, right? So, this means we will have to preprocess that data too because our machine only gets numbers. A JSON file by the name ‘intents.json’, which will contain all the necessary text that is required to build our chatbot. You will get a whole conversation as the pipeline output and hence you need to extract only the response of the chatbot here. Tutorials and case studies on various aspects of machine learning and artificial intelligence. In the code above, we first download the necessary NLTK data.

For a neuron of subsequent layers, a weighted sum of outputs of all the neurons of the previous layer along with a bias term is passed as input. The layers of the subsequent layers to transform the input received using activation functions. Before we dive into technicalities, let me comfort you by informing you that building your own Chatbot with Python is like cooking chickpea nuggets.

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. After the get_weather() function in your file, create a chatbot() function representing the chatbot that will accept a user’s statement and return a response.

This is where the chatbot becomes intelligent and not just a scripted bot that will be ready to handle any test thrown at them. The main package that we will be using in our code here is the Transformers package provided by HuggingFace. This tool is popular amongst developers as it provides tools that are pre-trained and ready to work with a variety of NLP tasks. As a cue, we give the chatbot the ability to recognize its name and use that as a marker to capture the following speech and respond to it accordingly. This is done to make sure that the chatbot doesn’t respond to everything that the humans are saying within its ‘hearing’ range.

  • The more keywords you have, the better your chatbot will perform.
  • This method computes the semantic similarity of two statements, that is, how similar they are in meaning.
  • The chatbot picked the greeting from the first user input (‘Hi’) and responded according to the matched intent.
  • The first step for us is to be able to install the chatbot library and for that we need to run the commands shown below.
