Chatbot: Definition, Types, Pros & Cons, Examples

Article Summary:

Chatbots, also known as chatterbots, are AI-powered tools used in messaging apps and various industries. They enhance customer interactions, operate based on set guidelines or machine learning, and have advantages like 24/7 availability. However, they can be limited and impersonal, making their implementation complex. Explore the world of chatbots in this comprehensive article.

What is a chatbot?

A chatbot is a computer program meticulously crafted to emulate human conversation, proficiently handling text chats or voice commands. These remarkable AI-driven entities, often referred to as chatterbots, possess the remarkable capability of seamless integration into major messaging applications. Their versatility is underscored by their ability to engage users in both textual and auditory dialogues.

Chatbots are, in essence, the digital ambassadors of our era. They bridge the gap between human users and technology, offering a novel and interactive means of communication. These intelligent software entities are not confined by geographical boundaries, as they are available around the clock, providing relentless customer support and information access.

According to industry research, the COVID-19 pandemic greatly accelerated the implementation and user adoption of chatbots around the globe.

Types of chatbots

Chatbots exhibit remarkable diversity in their operational paradigms, predominantly manifesting in two primary modes: those adhering to predefined guidelines and those leveraging the power of machine learning.

Set guidelines chatbot

Chatbots governed by stringent rule sets operate within well-defined boundaries. Their conversational prowess is restricted to specific inquiries and a predefined vocabulary. For example, an automated banking bot, when confronted with a user’s query, might respond with prompts like “account balances” or “bill payment.” However, if faced with an unexpected inquiry, these chatbots may falter, necessitating the redirection of users to human assistants.

Nonetheless, it’s worth noting that over time, the landscape of AI has undergone a transformative evolution, leading to a substantial decline in the prevalence of chatbots constrained by rigid guidelines.

Machine learning chatbot

Machine learning-based chatbots, in stark contrast, represent a more sophisticated breed. These intelligent entities harness the potential of artificial neural networks, mirroring the intricate nodes within the human brain. Equipped with a learning mechanism, they continually refine their conversational abilities as they encounter new dialogues and terminologies. In practice, as these chatbots engage with fresh voice or text-based interactions, their repertoire of responsive capabilities steadily expands, and the precision of their replies escalates.

Meta, formerly known as Facebook, boasts a machine learning chatbot that serves as a conduit for companies to engage with consumers via the Messenger application.
