Creating a ChatBot using ChatterBot Python

The consume_stream method pulls a new message from the queue from the message channel, using the xread method provided by aioredis. Next we get the chat history from the cache, which will now include the most recent data we added. The cache is initialized with a rejson client, and the method get_chat_history takes in a token to get the chat history for that token, from Redis. To handle chat history, we need to fall back to our JSON database. We’ll use the token to get the last chat data, and then when we get the response, append the response to the JSON database. The GPT class is initialized with the Huggingface model url, authentication header, and predefined payload.

Now, you can play around with your ChatBot as much as you want. To improve its responses, try to edit your intents.json here and add more instances of intents and responses in it. Okay, so now that you have a rough idea of the deep learning algorithm, it is time that you plunge into the pool of mathematics related to this algorithm. According to a Uberall report, 80 % of customers have had a positive experience using a chatbot. To select a response to your input, ChatterBot uses the BestMatch logic adapter by default.

The ChatGPT API comes with certain limitations and usage

restrictions to be aware of. These include pricing based on usage,

rate limits on the number of requests per minute and day, and a

maximum token limit per call. By default, the length is 2048 tokens,

but you can increase it to 4096 tokens for longer answers. The secret key is confidential information used to authenticate your API

requests.

• You should have a full conversation input and output with the model.
• As you notice, in line 8, a ‘while’ loop was created which will continue looping unless one of the exit conditions from line 7 are met.
• In human speech, there are various errors, differences, and unique intonations.
• This is also known as speech-to-text recognition as it converts voice data to text which machines use to perform certain tasks.

This logic adapter uses the Levenshtein distance to compare the input string to all statements in the database. It then picks a reply to the statement that’s closest to the input string. NLTK will automatically create the directory during the first run of your chatbot. Interact with your chatbot by requesting a response to a greeting. By specifying a session, the AIML can tailor different conversations to different people. For example, if one person tells the bot their name is Alice, and the other person tells the bot their name is Bob, the bot can differentiate the people.

How to Make a Chatbot in Python: Step by Step

Also, each actual message starts with metadata that includes a date, a time, and the username of the message sender. Now that you’ve created a working command-line chatbot, you’ll learn how to train it so you can have slightly more interesting conversations. It’s rare that input data comes exactly in the form that you need it, so you’ll clean the chat export data to get it into a useful input format. This process will show you some tools you can use for data cleaning, which may help you prepare other input data to feed to your chatbot. Building a Python AI chatbot is an exciting journey, filled with learning and opportunities for innovation.

These are some of the most popular Python libraries used for the development of AI chatbots, but there are many more libraries available, each with its own strengths and use cases. The right choice of the library depends on the specific requirements of the chatbot project. By default, model.generate() uses greedy search algorithm when no other parameters are set.

Preparing the Data

Let us consider the following snippet of code to understand the same. We will follow a step-by-step approach and break down the procedure of creating a Python chat. I’m here to listen, understand, and blend my tech prowess to create an app masterpiece.

Moreover, from the last statement, we can observe that the ChatterBot library provides this functionality in multiple languages. Thus, we can also specify a subset of a corpus in a language we would prefer. We will begin building a Python chatbot by importing all the required packages and modules necessary for the project. We will also initialize different variables that we want to use in it. Moreover, we will also be dealing with text data, so we have to perform data preprocessing on the dataset before designing an ML model. Unlike their rule-based kin, AI based chatbots are based on complex machine learning models that enable them to self-learn.

Then, save the file to an easily-accessible location like the Desktop. You can change the name to your preference, but make sure .py is appended. Make sure to replace the “Your API key” text with your own API key generated above. You can also delete API keys and create multiple private keys (up to five). Do note that you can’t copy or view the entire API key later on.

This will help us to reduce the bag of words by associating similar words with their corresponding root words.

How to create a Tkinter App in Python is out of the scope of this article but you can refer to the official documentation for more information. Interested in learning Python, read ‘Python API Requests- A Beginners Guide On API Python 2022‘. In the above output, we have observed a total of 128 documents, 8 classes, and 158 unique lemmatized words. In the above image, we are using the Corpus Data which contains nested JSON values, and updating the existing empty lists of words, documents, and classes.

This will avoid misrepresentation and misinterpretation of words if spelled under lower or upper cases. Python’s Tkinter is a library in Python which is used to create a GUI-based application. Lemmatization is grouping together the inflected forms of words into one word. For example, the root word or lemmatized word for trouble, troubling, troubled, and trouble is trouble.

Professors from Stanford University are instructing this course. There is extensive coverage of robotics, computer vision, natural language processing, machine learning, and other AI-related topics. It covers both the theoretical underpinnings and practical applications of AI. Students are taught about contemporary techniques and equipment and the advantages and disadvantages of artificial intelligence. The course includes programming-related assignments and practical activities to help students learn more effectively.

Step-by-Step Guide: Build AI Chatbot Using Python

To build a chatbot, it is important to create a database where all words are stored and classified based on intent. The response will also be included in the JSON where the chatbot will respond to user queries. Whenever the user enters a query, it is compared with all words and the intent is determined, based upon which a response is generated.

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.

Python Has a Healthy, Active, and Supportive Community

Chatbots can provide real-time customer support and are therefore a valuable asset in many industries. When you understand the basics of the ChatterBot library, you can build and train a self-learning chatbot with just a few lines of Python code. To a human brain, all of this seems really simple as we have grown and developed in the presence of all of these speech modulations and rules.

In the above image, we have created a bow (bag of words) for each sentence. Basically, a bag of words is a simple representation of each text in a sentence as the bag of its words. Tokenize or Tokenization is used to split a large sample of text or sentences into words. In the below image, I have shown the sample from each list we have created. The term “ChatterBot” was originally coined by Michael Mauldin (creator of the first Verbot) in 1994 to describe these conversational programs.

Then try to connect with a different token in a new postman session. We will give you a full project code outlining every step and enabling you to start. This code can be modified to suit your unique requirements and used as the foundation for a chatbot. The right dependencies need to be established before we can create a chatbot. Python and a ChatterBot library must be installed on our machine. With Pip, the Chatbot Python package manager, we can install ChatterBot.

Once the basics are acquired, anyone can build an AI chatbot using a few Python code lines. Artificial intelligence chatbots are designed with algorithms that let them simulate human-like conversations through text or voice interactions. Python has become a leading choice for building AI chatbots owing to its ease of use, simplicity, and vast array of frameworks. I am a full-stack software, and machine learning solutions developer, with experience architecting solutions in complex data & event driven environments, for domain specific use cases. When it gets a response, the response is added to a response channel and the chat history is updated.
