Building a Chatbot with Python: A Comprehensive Guide

This was a quick introduction to chatbots to present an understanding of how businesses are transforming using Data science and artificial Intelligence. In 1994, when Michael Mauldin produced his first chatbot and called it“Julia” and that’s the time when the word “chatterbot” entered first time in our dictionary. A chatbot is described as a computer program designed to simulate conversation with human users, particularly over the internet.

As you might notice when you interact with your chatbot, the responses don’t always make a lot of sense. You refactor your code by moving the function calls from the name-main idiom into a dedicated function, clean_corpus(), that you define toward the top of the file. In line 6, you replace „chat.txt” with the parameter chat_export_file to make it more general. The clean_corpus() function returns the cleaned corpus, which you can use to train your chatbot. Moving forward, you’ll work through the steps of converting chat data from a WhatsApp conversation into a format that you can use to train your chatbot.

Train your Python Chatbot with a Corpus of Data

The next step is to instantiate the Chat() function containing the pairs and reflections. First thing is to import the library and classes we need to use. Analytics Insight® is an influential platform dedicated to insights, trends, and opinion from the world of data-driven technologies. It monitors developments, recognition, and achievements made by Artificial Intelligence, Big Data and Analytics companies across the globe. Monitoring Bots – Creating bots to keep track of the system’s or website’s health.

This will allow a window to take input from the user and then the output can be shown on the screen with the help of functions we have created. After creating the pairs of rules above, we chatbot using the code below. The code is simple and prints a message whenever the function is invoked. NLTK stands for Natural Language Toolkit and is a leading python library to work with text data.

The library is designed in a way that makes it possible to train your bot in multiple programming languages. Although chatbot in python has already begun to dominate the tech scene at present, Gartner predicts that by 2020, chatbots will handle nearly 85% of the customer-brand interactions. This solved a major consumer pain point and made learning through the app a lot more fun. In addition, you can see the code powering LangChain’s Chat LangChain chatbot. We are going to use the Tkinter library to create a GUI for our chatbot.

Also, remember that when working with text data, you need to perform data preprocessing on your dataset before designing an ML model. When a user enters a specific input in the chatbot (developed on ChatterBot), the bot saves the input along with the response, for future use. This data (of collected experiences) allows the chatbot to generate automated responses each time a new input is fed into it.

Brief Intro on Chatbot

Chanin Nantasenamat, senior developer advocate at Streamlit, has a GitHub repository , YouTube video, and blog post to show you how. Now that we’ve separated our data, we are now ready to train our algorithm. However, Neural Networks expect numerical values, and not words, to be fed into them, therefore, we first have to process our data so that a neural network could read what we are doing.
