How To Build Your Own Chatbot Using Deep Learning by Amila Viraj
The best part is you don’t need coding experience to get started — we’ll teach you to code with Python from scratch. What is special about this platform is that you can add multiple inputs (users & assistants) to create a history or context for the LLM to understand and respond appropriately. This blog post will guide you through the process by providing an overview of what it takes to build a successful chatbot. To learn more about text analytics and natural language processing, please refer to the following guides. After creating the pairs of rules above, we define the chatbot using the code below.
If we look at the first element of this array, we will see a vector of the size of the vocabulary, where all the times are close to 0 except the ones corresponding to yes or no. They have to have the same dimension as the data that will be fed, and can also have a batch size defined, although we can leave it blank if we dont know it at the time of creating the placeholders. To build the entire network, we just repeat these procedure on the different layers, using the predicted output from one of them as the input for the next one. On the left part of the previous image we can see a representation of a single layer of this model.
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. To create a self-learning chatbot using the NLTK library in Python, you’ll need a solid understanding of Python, Keras, and natural language processing (NLP).
For example, Hello Sugar, a Brazilian wax and sugar salon in the U.S., saves $14,000 a month by automating 66 percent of customer queries. Plus, they’ve received plenty of satisfied reviews about their improved CX as well. Say No to customer waiting times, achieve 10X faster resolutions, and ensure maximum satisfaction for your valuable customers with REVE Chat.
By rethinking the role of your agents—from question masters to AI managers, editors, and supervisors—you can elevate their responsibilities and improve agent productivity and efficiency. You can foun additiona information about ai customer service and artificial intelligence and NLP. With AI and automation resolving up to 80 percent of customer questions, your agents can take on the remaining cases that require a human touch. While NLU and NLG are subsets of NLP, they all differ in their objectives and complexity.

First, you import the requests library, so you are able to work with and make HTTP requests. The next line begins the definition of the function get_weather() to retrieve the weather of the specified city. Next, you’ll create a function to get the current weather in a city from the OpenWeather API. You dive deeper into the data and discover that the chatbot isn’t providing clear instructions on how to place custom orders. Next, simply copy the installation code provided and paste it into the section of your website, right before the tag.
The similarity() method computes the semantic similarity of two statements as a value between 0 and 1, where a higher number means a greater similarity. Natural Language Processing (NLP) is a field of Artificial Intelligence (AI) that focuses on the interaction between computers and human language. It involves the ability of machines to understand, interpret, and generate human language, including speech and text. NLP plays a pivotal role in enabling chatbots to comprehend user inputs and generate appropriate responses. Let’s bring your conversational AI dreams to life with, one line of code at a time!
For this, computers need to be able to understand human speech and its differences. These insights are extremely useful for improving your chatbot designs, adding new features, or making changes to the conversation flows. I have already developed an application using flask and integrated this trained chatbot model with that application.
If you’re comfortable with these concepts, then you’ll probably be comfortable writing the code for this tutorial. If you don’t have all of the prerequisite knowledge before starting this tutorial, that’s okay! You can always stop and review the resources linked here if you get stuck. Instead, you’ll use a specific pinned version of Chat GPT the library, as distributed on PyPI. The first step to creating the network is to create what in Keras is known as placeholders for the inputs, which in our case are the stories and the questions. In an easy manner, these placeholders are containers where batches of our training data will be placed before being fed to the model.
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. The main loop continuously prompts the user for input and uses the respond function to generate a reply.
Challenges and Solutions in Building Python AI Chatbots
Typically, it begins with an input layer that aligns with the size of your features. The hidden layer (or layers) enable the chatbot to discern complexities in the data, and the output layer corresponds to the number of intents you’ve specified. The ChatterBot library combines language corpora, text processing, machine learning algorithms, and data storage and retrieval to allow you to build flexible chatbots. Also, consider the state of your business and the use cases through which you’d deploy a chatbot, whether it’d be a lead generation, e-commerce or customer or employee support chatbot. Operating on basic keyword detection, these kinds of chatbots are relatively easy to train and work well when asked pre-defined questions.
Some might say, though, that chatbots have many limitations, and they definitely can’t carry a conversation the way a human can. Handle conversations, manage tickets, and resolve issues quickly to improve your CSAT. You continue to monitor the chatbot’s performance and see an immediate improvement—more customers are completing the process, and custom cake orders start rolling in.
If you own a small online store, a chatbot can recommend products based on what customers are browsing, help them find the right size, and even remind them about items left in their cart. You can continue conversing with the chatbot and quit the conversation once you are done, as shown in the image below. I am a final year undergraduate who loves to learn and write about technology.
Now we have everything set up that we need to generate a response to the user queries related to tennis. We will create a method that takes in user input, finds the cosine similarity of the user input and compares it with the sentences in the corpus. Rather, we will develop a very simple rule-based chatbot capable of answering user queries regarding the sport of Tennis. But before we begin actual coding, let’s first briefly discuss what chatbots are and how they are used. Chatbots are the top application of Natural Language processing and today it is simple to create and integrate with various social media handles and websites.
Now, it must process it and come up with suitable responses and be able to give output or response to the human speech interaction. This method ensures that the chatbot will be activated by speaking its name. Natural language processing chatbots are used in customer service tools, virtual assistants, etc. Some real-world use cases include customer service, marketing, and sales, as well as chatting, medical checks, and banking purposes.
Many of these assistants are conversational, and that provides a more natural way to interact with the system. They operate based on predefined scripts and specific rules, similar to a “Choose Your Own Adventure” game. Users interact by selecting from a list of options, and the chatbot responds according to these pre-set rules. To do this, you’ll need a text editor or an IDE (Integrated Development Environment). A popular text editor for working with Python code is Sublime Text while Visual Studio Code and PyCharm are popular IDEs for coding in Python. NLTK stands for Natural Language Toolkit and is a leading python library to work with text data.

Building a Rule-Based Chatbot with Natural Language Processing
NLP stands for Natural Language Processing, a form of artificial intelligence that deals with understanding natural language and how humans interact with computers. In the case of ChatGPT, NLP is used to create natural, engaging, and effective conversations. NLP enables ChatGPTs to understand user input, respond accordingly, and analyze data from their conversations to gain further insights.
This is done to make sure that the chatbot doesn’t respond to everything that the humans are saying within its ‘hearing’ range. In simpler words, you wouldn’t want your chatbot to always listen in and partake in every single conversation. 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. NLP or Natural Language Processing has a number of subfields as conversation and speech are tough for computers to interpret and respond to.
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. Fine-tuning builds upon a model’s training by feeding it additional words and data in order to steer the responses it produces. Chat LMSys is known for its chatbot arena leaderboard, but it can also be used as a chatbot and AI playground. NLP-based chatbots dramatically reduce human efforts in operations such as customer service or invoice processing, requiring fewer resources while increasing employee efficiency.
As we continue on this journey there may be areas where improvements can be made such as adding new features or exploring alternative methods of implementation. Keeping track of these features will allow us to stay ahead of the game when it comes to creating better applications for our users. Once you’ve written out the code for your bot, it’s time to start debugging and testing it. I used 1000 epochs and obtained an accuracy of 98%, but even with 100 to 200 epochs you should get some pretty good results.
Speech Recognition works with methods and technologies to enable recognition and translation of human spoken languages into something that the computer or AI chatbot can understand and respond to. Creating a talking chatbot that utilizes rule-based logic and Natural Language Processing (NLP) techniques involves several critical tools and techniques that streamline the development process. This section outlines the methodologies required to build an effective conversational agent.
It allows chatbots to interpret the user intent and respond accordingly by making the interaction more human-like. A natural language processing chatbot is a software program that can understand and respond to human speech. NLP-powered bots—also known as AI agents—allow people to communicate with computers in a natural and human-like way, mimicking person-to-person conversations.
