What is a Chatbot?

Chatbot is an AI-powered system that allows conversation with humans. In other words, It is a conversational tool used in websites and apps to understand and answer human questions. Therefore, it uses AI and human language to offer real-time responses. So, when a user asks the bot a query, they will respond or act according to the need. As a result, you can develop chatbot from scratch based on your business needs and target audience.

Moreover, chatbot is similar to instant messaging, in that it takes place between a machine and a human. As mentioned earlier, these interactions are text or voice speech. Hence, your business can be active day and night without the aid of a human operator. Besides, chatbots use natural processing language (NPL) to respond to queries as a natural person.

So, now let us see how these chatbots work.

How do Chatbots Work?

Chatbots respond to the questions by using machine learning algorithms and pre-programmed scripts. As a result, when a user requests a question, the chatbot uses its available knowledge database to answer. So, if the user asks a query that introduces a new concept that the chatbot is not programmed to respond to, the chatbot passes it to the human operator to take the duty.

However, they will learn from the interaction and expand their knowledge database to answer similar questions. So, you can develop chatbot from scratch using these methods:

Pattern matching

Pattern matching is one of the classification methods chatbots use to respond to human queries. So, in pattern matching, the bot uses a pattern to produce suitable responses to human questions. In other words, they will answer anything relating to the associated paradigm.


Algorithm offers a unique paradigm for an advanced level of working. It involves a combination of patterns. As a result, it provides suitable answers to each type of question. Besides, algorithms reduce the use of classifiers. Hence, you will get a manageable structure.

For example, a set of sentences belongs to a class. Each word in the input sentences gets counted and assigned a score. The highest-scored type gets associated with the input sentences.

Artificial neural networks

Neural networks help develop chatbot from scratch. It involves using weighted connections by calculating output from the input. The bots then compute these connections from different iterations while training the data thousands of times. As a result, it improves the weights to make it more accurate.

What are the Components of Chatbot Architecture?

Chatbot architecture depends on the type of app that you build for your business. However, the basic components of chatbots remain the same. Below are the features you will see in a chatbot:

Q&A system

This feature is the one that is responsible for answering human queries. As a result, the Q&A system interprets the questions and gives an apt response from the knowledge base. Therefore, when you develop a chatbot from scratch, you can enjoy the benefits of chatbots, such as efficient customer support, round-the-clock availability, and streamlined interactions, by employing manual and automated training to generate a list of questions and answers


The environment helps contextualize users' messages using NLP. The NLP engine uses an advanced machine-learning algorithm to understand the user's search intent and match it to the bot's response list. Besides, they employ an intent classifier and entity extractor to provide what the user is looking for.

Front-end systems

This component is the client-facing system where the users interact with the chatbot. For example, a front-end system means your mobile apps and websites.

Traffic servers

Traffic or node servers deal with user requests. As a result, they route them to the proper internal components. So, when you develop chatbot from scratch, you can route responses from these components through servers to front-end systems.

Custom integrations

Another component of the chatbot is custom integration. It involves integrating your chatbot with back-end systems like CRM, payment apps, databases, etc. As a result, you can improve the capabilities of your chatbot.
