Conversational AI Chatbot with Transformers in Python

You can use the train method of the ChatBot class to train the chatbot with a set of conversation examples. For this, we are using OpenAI’s latest “gpt-3.5-turbo” model, which powers GPT-3.5. It’s even more powerful than Davinci and has been trained up to September 2021. It’s also very cost-effective, more responsive than earlier models, and remembers the context of the conversation. As for the user interface, we are using Gradio to create a simple web interface that will be available both locally and on the web.

Experiencing
a growth rate of 24.9%, chatbots have emerged as the fastest-growing medium for brand
communication. A corpus is a collection of authentic text or audio that has been organised into datasets. There are numerous sources of data that can be used to create a corpus, including novels, newspapers, television shows, radio broadcasts, and even tweets.

Now, we set top_k to 100 to sample from the top 100 words sorted descendingly by probability. Open Terminal and run the “app.py” file in a similar fashion as you did above. You will have to restart the server after every change you make to the “app.py” file. After that, set the file name as “app.py” and change “Save as type” to “All types” from the drop-down menu.

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. NLTK stands for Natural Language Toolkit and is a leading python library to work with text data. The first line of code below imports the library, while the second line uses the nltk.chat module to import the required utilities.

If your message data has a different/nested structure, just provide the path to the array you want to append the new data to. In the next section, we will focus on communicating with the AI model and handling the data transfer between client, server, worker, and the external API. In order to use Redis JSON’s ability to store our chat history, we need to install rejson provided by Redis labs. Next, to run our newly created Producer, update chat.py and the WebSocket /chat endpoint like below. Now that we have our worker we can create a producer on the web server and a consumer on the worker. We create a Redis object and initialize the required parameters from the environment variables.

Let us now explore step by step and unravel the answer of how to create a chatbot in Python. According to IBM, organizations spend over $1.3 trillion annually to address novel customer queries and chatbots can be of great help in cutting down the cost to as much as 30%. We then load the data from the file and preprocess it using the preprocess function. The function tokenizes the data, converts all words to lowercase, removes stopwords and punctuation, and lemmatizes the words.

Other than VS Code, you can install Sublime Text (Download) on macOS and Linux. Again, you may have to use python3 and pip3 on Linux or other platforms. We don’t know if the bot was joking about the snowball store, but the conversation is quite amusing compared to the previous generations. If it’s set to 0, it will choose the sequence from all given sequences despite the probability value. We highly recommend you use Jupyter Notebook or Google Colab to test the following code, but you can use any Python environment if you want.

So, here you go with the ingredients needed for the python chatbot tutorial. We then create a simple command-line interface for the chatbot that asks the user for input, calls the ‘predict_answer’ function to get the answer, and prints the answer to the console. If you’re not interested in houseplants, then pick your own chatbot idea with unique data to use for training. Repeat the process that you learned in this tutorial, but clean and use your own data for training. That way, messages sent within a certain time period could be considered a single conversation. ChatterBot uses complete lines as messages when a chatbot replies to a user message.

He made a bot called A.L.I.C.E. (Artificial Linguistics Internet Computer Entity) which won several
artificial intelligence awards. AIML is a form of XML that defines rules for matching patterns and determining responses. Artificial intelligence chat bots are easy to write in Python with the AIML package. AIML stands for Artificial Intelligence Markup Language, but it is
just simple XML.
