Creating a ChatBot using ChatterBot Python

We create a chatbot named “ByteScout.” Once done, we train the trainer with some outputs. To get started, you can use the data files hosted on GitHub. The module contains training data for multiple languages, and hence, is very flexible. Self-learning approach chatbots → These chatbots are more advanced and use machine learning. The self-learning approach of chatbots can be divided into two types. The reason is their incapability to understand human conversations completely.

Your Django server is now set up to handle chatbot API requests. In the next step, we’ll build a React frontend to interact with this API. This code includes the chatbot_app.urls module in your project’s URL routes. Any URL that starts with /api/ will be handled by the routes defined in chatbot_app.urls. Let’s have a quick recap as to what we have achieved with our chat system.

This means that there are no pre-defined set of rules for this chatbot. Instead, it will try to understand the actual intent of the guest and try to interact with it more, to reach the best suitable answer. It is also evident that people are more engrossed in messaging apps than simply passing through various social media.

Fine-Tuning Models using Prompt-Tuning with Hugging Face’s PEFT Library

Let us try to build a rather complex flask-chatbot using the chatterbot-corpus to generate a response in a flask application. This chatbot is going to solve mathematical problems, so ‘chatterbot.logic.MathematicalEvaluation’ is included. This logic adapter checks statements for mathematical equations. If one is present, a response is returned containing the result. The chatbot you’re building will be an instance belonging to the class ‘ChatBot’.

• We create a Redis object and initialize the required parameters from the environment variables.
• This way, you’ll receive notifications whenever new content is added.
• You can be a rookie, and a beginner developer, and still be able to use it efficiently.
• To generate a user token we will use uuid4 to create dynamic routes for our chat endpoint.
• It cracks jokes, uses emojis, and may even add water to your order.
• Hence, we create a function that allows the chatbot to recognize its name and respond to any speech that follows after its name is called.

After all of the functions that we have added to our chatbot, it can now use speech recognition techniques to respond to speech cues and reply with predetermined responses. However, our chatbot is still not very intelligent in terms of responding to anything that is not predetermined or preset. Artificially intelligent chatbots, as the name suggests, are designed to mimic human-like traits and responses. NLP (Natural Language Processing) plays a significant role in enabling these chatbots to understand the nuances and subtleties of human conversation. AI chatbots find applications in various platforms, including automated chat support and virtual assistants designed to assist with tasks like recommending songs or restaurants.

Creating the Chatbot with OpenAI and GPT.

It is a popular choice for building conversational interfaces and is used by businesses and developers worldwide. Artificial intelligence, specifically designed to improve human−computer interactions, utilises machine learning and Natural Language Processing (NLP) to create chatbots. Chatbots converse with humans in a natural, human−like manner by adapting to natural human language. 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. Let us have a quick glance at Python’s ChatterBot to create our bot. ChatterBot is a Python library built based on machine learning with an inbuilt conversational dialog flow and training engine.

You can use your desired OS to build this app – I am currently using MacOS, and Visual Studio Code. Huggingface also provides us with an on-demand API to connect with this model pretty much free of charge. You can read more about GPT-J-6B and Hugging Face Inference API. The Chat UI will communicate with the backend via WebSockets. In addition to all this, you’ll also need to think about the user interface, design and usability of your application, and much more.

In this function, you construct the URL for the OpenWeather API. This URL returns the weather information (temperature, weather description, humidity, and so on) of the city and provides the result in JSON format. After that, you make a GET request to the API endpoint, store the result in a response variable, and then convert the response to a Python dictionary for easier access.

Data and Analytics

To learn more about text analytics and natural language processing, please refer to the following guides. The other import you did above was Reflections, which is a dictionary that contains a set of input text and its corresponding output values. This is an optional dictionary and you can create your own dictionary in the same format as below. Recall that if an error is returned by the OpenWeather API, you print the error code to the terminal, and the get_weather() function returns None. In this code, you first check whether the get_weather() function returns None. If it doesn’t, then you return the weather of the city, but if it does, then you return a string saying something went wrong.

Now, most organizations have a chatbot that maintains logs of previous discussions. Then the developers use these logs to analyze what clients are trying to ask. Using machine learning tools and models, then the developers organize client inquiries and reply with the best suitable answer. To create a conversational chatbot, you could use platforms like Dialogflow that help you design chatbots at a high level. Or, you can build one yourself using a library like spaCy, which is a fast and robust Python-based natural language processing (NLP) library. SpaCy provides helpful features like determining the parts of speech that words belong to in a statement, finding how similar two statements are in meaning, and so on.

One of the best ways to learn how to develop full stack applications is to build projects that cover the end-to-end development process. You’ll go through designing the architecture, developing the API services, developing the user interface, and finally deploying your application. We will write a while loop and pass the functions inside it. I preferred using infinite while loop so that it repeats asking the user for an input. This is an extra function that I’ve added after testing the chatbot with my crazy questions. So, if you want to understand the difference, try the chatbot with and without this function.

The action you just performed triggered the security solution. There are several actions that could trigger this block including submitting a certain word or phrase, a SQL command or malformed data. We have a function which is capable of fetching the weather conditions of any city in the world. In the if block we ensure the status code of the API response is 200 (which means that we successfully fetched the weather information) and return the weather description.

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. For example, you may notice that the first line of the provided chat export isn’t part of the conversation. Also, each actual message starts with metadata that includes a date, a time, and the username of the message sender.

Python, a language famed for its simplicity yet extensive capabilities, has emerged as a cornerstone in AI development, especially in the field of Natural Language Processing (NLP). Its versatility and an array of robust libraries make it the go-to language for chatbot creation. This code defines a single URL route called chatbot that maps to the chatbot view defined in views.py. If the socket is closed, we are certain that the response is preserved because the response is added to the chat history. The client can get the history, even if a page refresh happens or in the event of a lost connection. It does not have any clue who the client is (except that it’s a unique token) and uses the message in the queue to send requests to the Huggingface inference API.

NLTK, or Natural Language Toolkit, is a leading platform for building Python programs to work with human language data. A reflection is a dictionary that proves advantageous in maintaining essential input and corresponding outputs. You can also create your own dictionary where all the input and outputs are maintained. You can learn more about implementing the Chatbot using Python by enrolling in the free course called “How to Build Chatbot using Python?

Eventually, you’ll use cleaner as a module and import the functionality directly into bot.py. But while you’re developing the script, it’s helpful to inspect intermediate outputs, for example with a print() call, as shown in line 18. In this example, you saved the chat export file to a Google Drive folder named Chat exports. You’ll have to set up that folder in your Google Drive before you can select it as an option.

Thus, the chatbot will gradually grow in scope and learn from previous experience and thus gain relevance. I have met an annoying one, a smart one, and even a kind one. So, let’s start at the very beginning and go step by step from there to build a simple stupid one.
