How to Make a Chatbot That Learns [in 2023]
While you can get the APIs of popular chatbots and integrate them into your customer service department, creating a chatbot that learns has its own privilege. You can tailor it according to your needs and corporate environment. Moreover, custom chatbots can adapt to user interactions and changing business environments.
So, how to make a chatbot that learns? Well, it may seem like you may need to learn the whole machine language, but making an AI chatbot that learns hardly takes more than 30 minutes. In this article, we’ve explained a step-by-step guide on how to make a chatbot using deep learning.
Part 1: What Is an AI Chatbot That Can Learn?
A chatbot that can learn is built by NLP algorithms and learning. It picks the intent of a message and replies accordingly. Moreover, it learns from the data that it is fed. The more you input information, the better it gets.
Therefore, an AI chatbot that learns can be chatbots that learns with deep learning, machine learning, or while chatting.
Part 2: How to Make a Chatbot That Learns?
Go through the process of choosing the best chatbot provider and creating a conversational flow by following this instruction.
1 Assign a goal to your chatbot
Decide on the goals you have for your chatbot. It is best to be as specific as possible. Summing up your objectives and outlining your specifications is crucial since the self-learning chatbot you develop for your website must meet exacting commercial standards.
It's time to move on to the "what" of your chatbot now that you have completed the "why." What precisely is your chatbot going to do? It will be much simpler to determine the features and kinds of chatbots you'll need once you get the answers.
2 Select the chatbot's platform
It's time to select the platform to create and set up the chatbot to learn. You have two options: the framework or the chatbot builder platform.
Framework: Software developers use chatbot frameworks (such Microsoft Bot, IBM Watson, and Google's Dialogflow) as libraries to create chatbots by coding.
Chatbot builder: They offer simple-to-use chatbot builders that let you make a chatbot using basic components. They are becoming more and more well-liked because it is much simpler and takes less time to construct bots with their assistance while still getting equivalent outcomes. Not to mention that certain services, like ChatInsight, offer plans that are free forever!
3 Customize your bot profile
By establishing the conversation flow, you can construct the chatbot. If the right foundation is in place, this procedure is almost as simple as dragging and dropping alternatives to respond to them. What you want is for the chatbot to understand the user intent, and that is accomplished by training the bot on all the different variants that consumers can ask for.
To train the bot, examine your client discussions to identify the most common questions and problems. Then, add the words, phrases, and questions related to a chosen subject (like shipping) to the Visitor says node.
4 Test your chatbot
It's time to verify that everything functions as it should now. You'll see a window that displays how the chatbot might appear to the final user. You may always return to the editor and fix the flow because of the preview.
Part 3: Create a Chatbot That Learns in Python
Creating a Chatbot in Python using deep learning requires certain prerequisites that we’ve explained above. Once you have them ready at your end, you can start with the installation.
How to create a chatbot with python and deep learning? Follow the step-by-step guide below:
1Importing the libraries and declaring constants
The first step is to import the libraries. We’ll be using the .ntfl library to preprocess data. This all covers tokenizing and lemmatizing words and sentences. The TensorFlow library will help the model in deep learning. We’ll need to read the .json file (we’ll add words and labels from it in the preprocess).
Similarly, numpy will convert data into array form for better computer algorithm understanding. Finally to save labels and words to our model we’ll use Pickle.
Once done with importing, we have to set constants to be used as a framework to separate sentences.
2Loading the .json file
Next load the .json file for the words and labels. You’ll see an intent code in the source code too. That’ll help our chatbot to pick the intent of a phrase or sentence.
3Preprocessing
To make the chatbot a success, we need to preprocess our raw data so that it's ready to fit into the deep learning model.
- Step 1.First we’ll iterate our intents and patterns and then tokenize them.
- Step 2.Then add documents to the data corpus by appending the tokenized words to their respective word list.
- Step 3.Finally create a list of labels for the tags.
4Lemitizing the words and saving them using pickle
Lemmatizing means converting words or phrases into lemma forms. In simpler words, this source code will reduce long words into short ones which will assist the chatbot to better understand the user intent.
Remember we wrote above that pickle will be used to save the words and lists. So now we’ll save the words and label lists that we created from the pickle library.
5Creating the training data
Next we’ll create the training data. We need an input constant and an output constant to set up the response mechanism for our chatbot. Input will be our pattern in the form of bag_of_words. Bag_of_words represents textual data in numbers, commonly 0 and 1 for the computer algorithm to easily pick the input.
The output will be in the form of the row which will tell in which label our pattern is located.
6Converting the newly created data into array form and splitting it into trains
Now we’ll convert our data into a numpy array using the numpy library. This will simplify the optimization of data and help in efficient numerical computations.
Next, we’ll spit it into x_train and y_train. X_train represents the words while Y_train means labels.
7Creating the model and saving it
After passing the preprocess and training our data, we’ll create our model. The model will have a connected input and an output layer.
Done with the creation? Now we have to save our hard work.
All we need to start chatting with our chatbot is to create another Python file and load our created model, words, and lists.
8Running the model
To make our model respond to random queries we have to create a function. This function will filter the intent out of the text and then predict the correct label for it. Here's the source code for creating a function.
Similarly here's the source code for a function that will pick the right label out of the whole list based on your intent.
Combining the previous two functions we can create a model that can offer seamless interaction between the user and the bot.
Next step? Just run the Python file and enjoy communicating with your new bot.
Part 4: Where to Implement an AI ChatBot That Learns?
Self-learning chatbots can help in customer service. They can deal with customer inquiries, negative reviews, and suggestions. They can help roll out promotional campaigns for your new launch and can even assist customers in choosing a product.
These bots can also be used in ecommerce. They can offer order status tracking, product recommendations, and customer user interface according to user intent.
AI chatbots with deep learning can be your next HR manager. With NLP, you can integrate it with your job surveys and hiring posts to pick the best matched employees. Moreover, HR managers can use it to inquire about relevant questions from employees.
Last but not least, the self-learning AI chatbots will be your writing assistants, which means that they can write emails, essays, blogs, and other content you need after fed with data, and you can improve your writing skills with their help.
Part 5: Benefits of Creating Your Own Chatbot That Learns
Creating your own Chatbot with Python and deep learning might take long, but it's worth it in terms of benefits over non-customizable chatbots.
1. Customization
Self-learning bots offer the highest customization. You can swipe around different features and make it the perfect assistance for your department.
2. Scalability
