A chatbot is a computer program that resembles and interprets spoken or written human conversations, enabling people to engage with digital gadgets in the same way they would with a real person.A chatbot can be as basic as a program that responds to a straightforward question with a single line of text. Using prior data sets, machine learning can be used to develop a chatbot. It forecasts the appropriate response by using the knowledge gained from our earlier data sets. It makes use of machine learning algorithms, such as natural language processing algorithms, for prediction. Conventionally designed chatbots have a number of shortcomings, such as a narrow focus and a lack of customisation.Therefore, in order to improve user experience and elevate our chatbots with effective natural language processing, we apply adaptive personalization approaches. These techniques allow us to modify interactions based on individual preferences and past encounters, which in turn fosters greater engagement and connection.Simple duties like responding to often requested questions can be handled by them, as well as more complicated ones like booking reservations and offering tailored recommendations. Users can readily access them as they can be integrated with various systems and platforms, such messaging apps and social media. Chatbots are becoming a necessary tool for organizations to stay competitive in the market, as the need for digital solutions rises.
