If a match is found, the current intent gets selected and is used as the key to the responses dictionary to select the correct response. Here, we first defined a list of words list_words that we will be using as our keywords. We used WordNet to expand our initial list with synonyms of the keywords. Let us consider the following snippet of code to understand the same. Monitoring Bots – Creating bots to keep track of the system’s or website’s health. Transnational Bots are bots that are designed to be used in transactions.

  • This website is using a security service to protect itself from online attacks.
  • ChatterBot is a Python library built based on machine learning with an inbuilt conversational dialog flow and training engine.
  • Lastly, the hands-on demo will also give you practical knowledge of implementing chatbots in Python.
  • You need to specify a minimum value that the similarity must have in order to be confident the user wants to check the weather.

Once the intent is identified, the bot will then pick out a response appropriate to the intent. In this second part of the series, we’ll be taking you through how to build a simple Rule-based chatbot in Python. Before we start with the tutorial, we need to understand the different types of chatbots and how they work. A Chatbot is an Artificial Intelligence-based software developed to interact with humans in their natural languages. These chatbots are generally converse through auditory or textual methods, and they can effortlessly mimic human languages to communicate with human beings in a human-like way. A chatbot is considered one of the best applications of natural languages processing.

Implementing inline means that writing @ + bot’s name in any chat will activate the search for the entered text and offer the results. By clicking one of them the bot will send the result on your behalf (marked “via bot”). PyTelegramBotAPI offers using the @bot.callback_query_handler decorator which will pass the CallbackQuery object into a nested function. After that, Telegram will send all the updates on the specified URL as soon as they arrive.

But, if you want the chatbot to recommend products based on customers’ past purchases or preferences, a self-learning or hybrid chatbot would be more suitable. 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. That way, messages sent within a certain time period could be considered a single conversation.

Also, a good understanding of how apps work would be a good addition, but not a must, as we will be going through most of the stuff we present in detail. In this article, Toptal Natural Language Processing Developer Ali Abdel Aal demonstrates how you can create and deploy a Telegram chatbot in a matter of hours. All the API implementations are stored in a single class called TeleBot.

In this article, we share Apriorit’s expertise building smart chatbots in Python. We explore what chatbots are and how they work, and we dive deep into two ways of writing smart chatbots. In the practical part of this article, you’ll find detailed examples of an AI-based bot in Python built using the DialoGPT model and an ML-based bot built using the ChatterBot library. Thanks to its extensive capabilities, artificial intelligence (AI) helps businesses automate their communication with customers while still providing relevant and contextual information.

Step 3 — Creating the Chatbot

If you scroll further down the conversation file, you’ll find lines that aren’t real messages. Because you didn’t include media files in the chat export, WhatsApp replaced these files with the text . To start off, you’ll learn how to export data from a WhatsApp chat conversation. 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. The call to .get_response() in the final line of the short script is the only interaction with your chatbot.

This function will take the city name as a parameter and return the weather description of the city. The best part about ChatterBot is that it provides such functionality in many different languages. You can also select a subset of a corpus in whichever language you prefer. Neural networks calculate the output from the input using weighted connections. They are computed from reputed iterations while training the data.

Step 2 – Creating the chatbot function

Instead, you’ll use a specific pinned version of the library, as distributed on PyPI. You’ll find more information about installing ChatterBot in step one. Radek Fabisiak was with the computers from his early days, remembers an orange screen with Win32, big floppy disks, and the sound of dial-up connecting to the internet. He has got experience in full-stack development by working for top IT companies like Microsoft.

Now that you have imported the relevant classes, it’s time to create an instance of the chatbot, which is an instance of the class ‘ChatBot’. Once you create a new ChatterBot instance, you need to train the bot to make it more efficient. The training will aim to supply the right information to the bot so that it will be able to return appropriate responses to users.


I am very enthusiastic about programming and its real applications including software development, machine learning and data science. Another major section of the chatbot development procedure is developing the training and testing datasets. This is where tokenizing supports text data – it converts the large text dataset into smaller, readable chunks (such as words). Once this process is complete, we can go for lemmatization to transform a word into its lemma form. Then it generates a pickle file in order to store the objects of Python that are utilized to predict the responses of the bot. When a user inserts a particular input in the chatbot (designed on ChatterBot), the bot saves the input and the response for any future usage.

You should take note of any particular queries that your chatbot struggles with, so that you know which areas to prioritise when it comes to training your chatbot further. 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.

You save the result of that function call to cleaned_corpus and print that value to your console on line 14. ChatterBot uses the default SQLStorageAdapter and creates a SQLite file database unless you specify a different storage adapter. For this tutorial, you’ll use ChatterBot 1.0.4, which also works with newer Python versions on macOS and Linux. ChatterBot 1.0.4 comes with a couple of dependencies that you won’t need for this project. However, you’ll quickly run into more problems if you try to use a newer version of ChatterBot or remove some of the dependencies.

Understanding the recipe requires you to understand a few terms in detail. Don’t worry, we’ll help you with it but if you think you know about them already, you may directly jump to the Recipe section. Before we dive into technicalities, let me comfort you by informing you that building your own Chatbot with Python is like cooking chickpea nuggets.

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(). Here, we will create a function that the bot will use to acquire the current weather in a city.

In other words, a chatbot simulates a human-like conversation in order to perform a specific task for an end user. These tasks may vary from delivering information to processing financial transactions to making decisions, such as providing first aid. In this guide, you learned about creating a simple chatbot in Python. You used simple rules and the powerful nltk library to build the chatbot.

In particular, smart chatbots imitate natural human language in order to communicate with users in a human-like manner. Chatbots are software tools created to interact with humans through chat. The first chatbots were able to create simple conversations based on a complex system of rules.
