Intelligent conversational computer systems, such as chatbots, imitate human speech to provide online assistance and assistance in the form of automated responses. Many sectors have used chatbots to deliver virtual support to clients as a result of the enhanced advantages they provide. Natural Language Processing and Machine Learning are two areas of Artificial Intelligence that are heavily included into chatbots. Before the advent of chatbots, there were just bots. The emergence of chatbots has ushered in a new age of conversational computing. A method of conversion that is participatory. A textual chatbot is a computer programme that can have a meaningful conversation with a real person. A chatbot can be built on a variety of cloud-based platforms these days, including Microsoft Bot Framework and IBM Watson. However, each of these technologies has its own pros and cons (such as built-in artificial intelligence, natural language processing, conversion services and programming), so it's important to weigh the advantages and disadvantages of each before making a decision. Cloud-based chatbot systems are compared to determine which is the most effective, including those that include built-in artificial intelligence (AI). A comparison will tell which cloud platform is best suitable for constructing chatbots.
