Retrieval based chatbot on Tarumanagara University with multilayer perceptron

Abstract

Natural Language Processing or NLP is a branch of Artificial Intelligence that focuses on processing language. One of the implementation of NLP is in the field of customer service in the form of chatbots. Tarumanagara University itself already has a customer service called Admission Tarumanagara. Admission can be contacted by telephone or sending an e-mail message. Making Chatbot will add ways to get information about Tarumanagara University. Chatbot is a computer program based on artificial intelligence that can simulate conversations between people. The system created is a Retrieval Based Chatbot system that can recognize user questions and answer user questions directly. Making a chatbot system will use a model with the Multilayer Perceptron method. The process for the system will go through two stages, namely the preprocessing stage and the introduction stage. The preprocessing stage consists of case lowering, tokenizing, and stemming. After that the model is made and the introduction phase of the trained model is carried out. Chatbot that has been made can be accessed using the LINE application via LINE ID @764vvcfm.
