Creating ChatBot Using Natural Language Processing in Python Engineering Education EngEd Program

Today most of the companies, business from different sector makes use of chatbot in a different way to reply their customer as fast as possible. Chatbots also help in increasing traffic of site which is top reason of business to use chatbots. A chatbot is an AI-based software that comes under the application of NLP which deals with users to handle their specific queries without Human interference.


Almost 30 percent of the tasks are performed by the chatbots in any company. Companies employ these chatbots for services like customer support, to deliver information, etc. Although the chatbots have come so far down the line, the journey started from a very basic performance.

How to build a simple chatbot using Python in few minutes

Check out this comparison table for a quick side-by-side view of the best chatbot framework options. Let’s look at some advantages and disadvantages to weigh it out. Literally, the words are converted into a form of ones and zeros which are then appended to the training list as well as the output list and then converted to NumPy arrays. The responses are described in another dictionary with the intent being the key. In the dictionary, multiple such sequences are separated by theOR|operator.


Logic adapters determine the logic for how a response to a given query is selected. If multiple adapters are used, the bot will return the response with the highest calculated confidence value. If multiple adapters return the same confidence, the first adapter from the adapter list will be chosen. All these specifics make the transformer model faster for text processing tasks than architectures based on recurrent or convolutional layers. RNNs process data sequentially, one word for input and one word for the output. In the case of processing long sentences, RNNs work too slowly and can fail at handling long texts.

This framework has an easy setup, it has been optimized for real-world use cases, automatic batching requests, and dozens of other compelling features such as intuitive APIs. BotMan is framework agnostic, meaning you can use it in your existing codebase with whatever framework you want. BotMan is about having an expressive, yet powerful syntax that allows you to focus on the business logic, not on framework code. Claudia will automatically set up the correct webhooks for all the supported platforms and guide you through configuring the access, so you can get started quickly. With OpenDialog you can deploy, integrate and train efficiently. Their smart conversation engine allows users to customize and integrate as required.

  • In line 6, you replace «chat.txt» with the parameter chat_export_file to make it more general.
  • Explore what clients say about working with Apriorit and read detailed case studies of how our specialists deliver IT products.
  • About 90% of companies that implemented chatbots record large improvements in the speed of resolving complaints.
  • For 20+ years, we’ve been delivering software development and testing services to hundreds of clients worldwide.
  • Depending on the amount and quality of your training data, your chatbot might already be more or less useful.
  • That way, messages sent within a certain time period could be considered a single conversation.

We can use the get_response() function in order to interact with the Python chatbot. Let us consider the following execution of the program to understand it. In the above snippet of code, we have imported two classes — ChatBot from chatterbot and ListTrainer from chatterbot.trainers. Another amazing feature of the ChatterBot library is its language independence.


The output layer gives the probabilities of different words there in the training data. Here eachintent contains a tag, patterns, responses, and context. Patterns are the data that the user is more likely to type and responses are the results from the chatbot.

The more python chatbot library you have, the better your chatbot will perform. 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. The simplest form of Rule-based Chatbots have one-to-one tables of inputs and their responses. These bots are extremely limited and can only respond to queries if they are an exact match with the inputs defined in their database.

How ChatterBot Works¶

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. Many of these assistants are conversational, and that provides a more natural way to interact with the system. In this section, you put everything back together and trained your chatbot with the cleaned corpus from your WhatsApp conversation chat export. At this point, you can already have fun conversations with your chatbot, even though they may be somewhat nonsensical.

Which IDE is the best for Python AI?

  • IDLE. IDLE (Integrated Development and Learning Environment) is a default editor that accompanies Python.
  • PyCharm. PyCharm is a widely used Python IDE created by JetBrains.
  • Visual Studio Code. Visual Studio Code is an open-source (and free) IDE created by Microsoft.
  • Sublime Text 3.
  • Atom.
  • Jupyter.
  • Spyder.
  • PyDev.

The ChatterBot library comes with some corpora that you can use to train your chatbot. However, at the time of writing, there are some issues if you try to use these resources straight out of the box. In the previous step, you built a chatbot that you could interact with from your command line. The chatbot started from a clean slate and wasn’t very interesting to talk to. In line 8, you create a while loop that’ll keep looping unless you enter one of the exit conditions defined in line 7.

The clean_corpus() function returns the cleaned corpus, which you can use to train your chatbot. ChatterBot uses complete lines as messages when a chatbot replies to a user message. In the case of this chat export, it would therefore include all the message metadata. That means your friendly pot would be studying the dates, times, and usernames!

You can add as many key-value pairs to the dictionary as you want to increase the functionality of the chatbot. Finally, you have created a chatbot and there are a lot of features you can add to it. To extract the named entities we use spaCy’s named entity recognition feature. If it is then we store the name of the entity in the variable city.

A chatbot is a computer program that holds an automated conversation with a human via text or speech. 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. Over the years, we’ve worked on many cloud, data management, and cybersecurity projects, building extensive expertise in fast and secure web application development.
