A ChatBot aims to make a conversation between both human and machine. The machine has been embedded knowledge to identify the sentences and making a decision itself as a response to answer the questions. The college enquiry ChatBot will be developed using Artificial Intelligence algorithms that analyzes student queries such as date and timing of annual day, sports day, and other cultural activities. The student does not have to personally go to the college for enquiry. Students can use this system for enquiries at any point in time. The knowledge base of ChatBot is already in the database. The chatbot consists of interface that accesses data from the knowledge base. The query of the student is treated as a sentence by the system. Then Naïve Bayes algorithm consists pre-processing, stop word process that divides input sentence as two letters of input. The sentence similarity score will be calculated by matching input sentence with the knowledge base. The higher scored sentence will be more similar to the input sentence. With the help of artificial intelligence, the system answers the query asked by the student. The system replies to the user query using the higher scored sentence. An effective GUI which implies that as if a real person is chatting with the user.
