Building a rule-based chatbot in Python

Encoder-only Transformers are great at understanding text (sentiment analysis, classification, etc.) because Encoders encode meaningful representations. Decoder-only models are great for generation (such as GPT-3), since decoders are able to infer meaningful representations into another sequence with the same meaning. Otherwise, if the cosine similarity is not equal to zero, that means we found a sentence similar to the input in our corpus. In that case, we will just pass the index of the matched sentence to our «article_sentences» list that contains the collection of all sentences. Finally, we flatten the retrieved cosine similarity and check if the similarity is equal to zero or not. If the cosine similarity of the matched vector is 0, that means our query did not have an answer.

  • If you haven’t installed the Tkinter module, you can do so using the pip command.
  • Most consider it an example of generative deep learning, because we’re teaching a network to generate descriptions.
  • The best part about ChatterBot is that it provides such functionality in many different languages.
  • The point of the tutorial is to show you how the webhook reads the request data from the chatbot, and to show you the format of the data that must be returned to the chatbot.

If you need more advanced path handling, then take a look at Python’s pathlib module. Lines 12 and 13 open the chat export file and read the data into memory. 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 .

Chatbot with Python

Unlike rule-based chatbots, they analyze what the user wants and react accordingly. These bots use custom keywords and machine learning to respond more efficiently and chatbot using python effectively to user queries. As we mentioned above, you can create a smart chatbot using natural language processing , artificial intelligence, and machine learning.

The library is developed in such a manner that makes it possible to train the bot in more than one programming language. Try adding a special case to allow the user to address ’Brobot’ by name in addition to ’you’ to set up a response that refers to the bot itself. Framing the problem as one of translation makes it easier to figure out which architecture we’ll want to use.

Why learn AI?

We will follow a step-by-step approach and break down the procedure of creating a Python chat. Otherwise, just reconstruct the base words from the user’s original sentence—subject, verb, object—and add some bro-ish filler. If they said anything else, the bot will just mindlessly echo what they said, adding some filler bro-words at the end. Like a real brogrammer, our bot is limited in its intellectual capability and mostly regurgitates aphorisms it saw elsewhere, like LinkedIn. I’m going to look for pronouns like “you” or “I” and infer from those that the user wants to talk about themselves or the bot.


It is a Python library that generates a response to user input. Several machine learning algorithms based on neural networks were used to create the various reactions. It makes it easier for the user to create a bot using the chatbot library to get more accurate answers. The chatbot’s design is such that the bot can interact in many languages, including Spanish, German, English, and many regional languages. Machine learning algorithms also allow the bot to improve itself with user input. A chatbot is a computer program that is designed to simulate a human conversation.

The first parameter, ‘name’, represents the name of the Python chatbot. Another parameter called ‘read_only’ accepts a Boolean value that disables or enables the ability of the bot to learn after the training. We have also included another parameter named ‘logic_adapters’ that specifies the adapters utilized to train the chatbot. Chatbots are conversational agents that engage in different types of conversations with humans. Chatbots are finding their place in different strata of life ranging from personal assistant to ticket reservation systems and physiological therapists.

It becomes easier for the users to make chatbots using the ChatterBot library with more accurate responses. Nobody likes to be alone always, but sometimes loneliness could be a better medicine to hunch the thirst for a peaceful environment. Even during such lonely quarantines, we may ignore humans but not humanoids. Yes, if you have guessed this article for a chatbot, then you have cracked it right. We won’t require 6000 lines of code to create a chatbot but just a six-letter word “Python” is enough.

As we can see, our bot can generate a few logical responses, but it actually can’t keep up the conversation. Let’s make some improvements to the code to make our bot smarter. The transformer model we used for making an AI chatbot in Python is called the DialoGPT model, or dialogue generative pre-trained transformer.

Correctly importing code will increase your productivity by allowing you to reuse code while also maintaining the maintainability of your projects. In just one minute, you can deploy apps as close as possible to your users. After creating your cleaning module, you can now head back over to bot.py and integrate the code into your pipeline. Lines 17 and 18 use Python’s name-main idiom to call remove_chat_metadata() with «chat.txt» as its argument, so that you can inspect the output when you run the script. ChatterBot uses the default SQLStorageAdapter and creates a SQLite file database unless you specify a different storage adapter.

Going Further – Hand-Held End-to-End Project

There are plenty of rules to follow and if we want to add more functionalities to the chatbot, we will have to add more rules. Rule-based chatbots are pretty straight forward as compared to learning-based chatbots. If the user query matches any rule, the answer to the query is generated, otherwise the user is notified that the answer to user query doesn’t exist.

However, you can fine-tune the model with your dataset to achieve better performance. 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. This tutorial provides you with easy to understand steps for a simple file system filter driver development. The demo driver that we show you how to create prints names of open files to debug output.

chatbot using python

In this example, we get a response from the chatbot according to the input that we have given. Let us try to build a rather complex flask-chatbot using the chatterbot-corpus to generate a response in a flask application. ChatterBot makes it easy to create software that engages in conversation. Every time a chatbot gets the input from the user, it saves the input and the response which helps the chatbot with no initial knowledge to evolve using the collected responses. The design of ChatterBot is such that it allows the bot to be trained in multiple languages.
