A Simple Guide To Building A Chatbot Using Python Code

How to Build Your AI Chatbot with NLP in Python?

how to build chatbot using python

Before we start building, let’s take a moment to understand what a chatbot is. A chatbot, in its simplest form, is an AI-powered software designed to interact with humans in their natural languages. These interactions usually occur through messaging applications, websites, mobile apps or through the telephone. In this article, we have learned how to make a chatbot in python using the ChatterBot library using the flask framework. Don’t be in the sidelines when that happens, to master your skills enroll in Edureka’s Python certification program and become a leader.

  • After data cleaning, you’ll retrain your chatbot and give it another spin to experience the improved performance.
  • Here is an example of the list of messages that can be sent using the three available roles.
  • There’s a chance you were contacted by a bot rather than human customer support professional.
  • To send messages between the client and server in real-time, we need to open a socket connection.
  • We will set value 1 to only those indexes that contain the word in the patterns.

The year 1979 saw Danish computer scientist, ‘Bjarne Stroustrup’ working on a project of C language, that he called ‘C with Classes’. The future bots, however, will be more advanced and will come with features like multiple-level communication, service-level automation, and manage tasks. That’s a step up compared to old bots that were limited in their automation and approach. Ok with the above libraries installed we are good to go with the coding part. You can type a “hi” and “I’m good” to check if the mood bot is working fine or not. The next step is to instantiate the Chat() function containing the pairs and reflections.

You can also catch messages using regexp, their content-type and with lambda functions. At their core, all these libraries are HTTP requests wrappers. A great deal of them is written using OOP and reflects all the Telegram Bot API data types in classes. It also allows a basic configuration (description, profile photo, inline support, etc.).

You will learn about types of chatbots and multiple approaches for building the chatbot and go through its top applications in various fields. Further, you will understand its architecture and mechanism through understanding the stages and processes involved in detail. Lastly, the hands-on demo will also give you practical knowledge of implementing chatbots in Python.

We will be using a free Redis Enterprise Cloud instance for this tutorial. 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. Redis is an open source in-memory data store that you can use as a database, cache, message broker, and streaming engine. It supports a number of data structures and is a perfect solution for distributed applications with real-time capabilities.


ChatterBot provides a way to install the library as a Django app. As a next step, you could integrate ChatterBot in your Django project and deploy it as a web app. 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. In this example, you saved the chat export file to a Google Drive folder named Chat exports. You’ll have to set up that folder in your Google Drive before you can select it as an option.

Exploring Natural Language Processing (NLP) in Python

The project requires you to have good knowledge of Python, Keras, and Natural language processing (NLTK). Along with them, we will use some helping modules which you can download using the python-pip command. In a few simple steps, you can add a Dialogflow chatbot to your Python frameworks.

WebSockets are a very broad topic and we only scraped the surface here. This should however be sufficient to create multiple connections and handle messages to those connections asynchronously. Lastly, the send_personal_message method will take in a message and the Websocket we want to send the message to and asynchronously send the message.

In simpler words, you wouldn’t want your chatbot to always listen in and partake in every single conversation. Hence, we create a function that allows the chatbot to recognize its name and respond to any speech that follows after its name is called. In this article, we will create an AI chatbot using Natural Language Processing (NLP) in Python.

We then created a simple command-line interface for the chatbot and tested it with some example conversations. Using the ChatterBot library and the right strategy, you can create chatbots for consumers that are natural and relevant. Professors from Stanford University are instructing this course.

Voice Chatbots for Customer Service: A Comprehensive Guide

In this article, we will guide you to combine speech recognition processes with an artificial intelligence algorithm. Building a chatbot can be a challenging task, but with the right tools and techniques, it can be a fun and rewarding experience. In this tutorial, we’ll be building a simple chatbot using Python and the Natural Language Toolkit (NLTK) library. Chatterbot combines a spoken language data database with an artificial intelligence system to generate a response.

We thus have to preprocess our text before using the Bag-of-words model. Few of the basic steps are converting the whole text into lowercase, removing the punctuations, correcting misspelled words, deleting helping verbs. But one among such is also Lemmatization and that we’ll understand in the next section. For computers, understanding numbers is easier than understanding words and speech. When the first few speech recognition systems were being created, IBM Shoebox was the first to get decent success with understanding and responding to a select few English words.

In the same way, we will create the output by setting 1 to the class input the pattern belongs to. In the end, the words contain the vocabulary of our project and classes contain the total entities to classify. To save the python object in a file, we used the pickle.dump() method. These files will be helpful after the training is done and we predict the chats. In this article we will build an interesting project on Chatbot.
