ChatterBot: Build a Chatbot With Python

For instance, under the name tag, a user may ask someone’s name in a variety of ways — “What’s your name? In the above snippet of code, we have imported two classes – ChatBot from chatterbot and ListTrainer from chatterbot.trainers. The second step in the Python chatbot development procedure is to import the required classes. Neural networks calculate the output from the input using weighted connections.

Features that would have taken you days or weeks to develop require just a few clicks to implement into your website. And having access to the source code, you can always choose and manage components yourself. The code above will generate the following chatbox in your notebook, as shown in the image below. The next step is to instantiate the Chat() function containing the pairs and reflections.

How To Make A Chatbot In Python?

Now, you will create a chatbot to interact with a user in natural language using the weather_bot.py script. Interacting with software can be a daunting task in cases where there are a lot of features. In some cases, performing similar actions requires repeating steps, like navigating menus or filling forms each time an action is performed. Chatbots are virtual assistants that help users of a software system access information or perform actions without having to go through long processes.

Then it’s possible to call any Telegram Bot API methods from a bot variable. Now your Python chat bot is initialized and constantly requests the getUpdates method. The none_stop parameter is responsible for polling to continue even if the API returns an error while executing the method. You can find a list of all Telegram Bot API data types and methods here. If the user/bot does not have the chatmoderator right, a kick will not preform. We have a function which is capable of fetching the weather conditions of any city in the world.

Build a Chatbot with Python

After we execute the above program we will get the output like the image shown below. After we are done setting up the flask app, we need to add two more directories static and templates for HTML and CSS files. We initialise the chatbot by creating an instance of it and giving it a name. Here, we call it, ‘MedBot’, since our goal is to make this chatbot work for an ENT clinic’s website.

• But, we have to set a minimum value for the similarity to make the chatbot decide that the user wants to know about the temperature of the city through the input statement.
• Alternatively, you could parse the corpus files yourself using pyYAML because they’re stored as YAML files.
• Next, we define a function get_weather() which takes the name of the city as an argument.
• It is one of the trending platform for working with human data and developing application services which are able to understand it.
• About 90% of companies that implemented chatbots record large improvements in the speed of resolving complaints.

Use the ChatterBotCorpusTrainer to train your chatbot using an English language corpus. Import ChatterBot and its corpus trainer to set up and train the chatbot. 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 do not have the Tkinter module install, then first install it using the pip command. Chatbot asks for basic information of customers like name, email address, and the query. You have successfully created an intelligent chatbot capable of responding to dynamic user requests.

Code Walkthrough

These bots are extremely limited and can only respond to queries if they are an exact match with the inputs defined in their database. Wit.ai is an open-source chatbot framework that was acquired by Facebook in 2015. Being open-source, you can browse through the existing bots and apps built using Wit.ai to get inspiration for your project. Instead of defining visual flows and intents within the platform, Rasa allows developers to create stories (training data scenarios) that are designed to train the bot.

We can also output a default error message if the chatbot is unable to understand the input data. After you’ve completed that setup, your deployed chatbot can keep improving based on submitted user responses from all over the world. You can imagine that training your chatbot with more input data, particularly more relevant data, will produce better results. All of this data would interfere with the output of your chatbot and would certainly make it sound much less conversational.

Build a simple Chatbot using NLTK Library in Python

After deploying the virtual assistants, they interactively learn as they communicate with users. Think of it this way—the bot platform is the place where chatbots interact with users and perform different tasks on your behalf. A chatbot development framework is a set of coded functions and elements that developers can use to speed up the process of building bots. This blog was a hands-on introduction to building a very simple rule-based chatbot in python. You can easily expand the functionality of this chatbot by adding more keywords, intents and responses.
