Conversational Recommender System Chatbot Based on Functional Requirement

To make a decision in choosing a product with insufficient information or knowledge, we can use a recommendation. Recommender system is a system that gives recommendation to user. In recommendation system that recommends product, user requirements can be given as technical requirement or functional requirement. User that not familiar with technical specification of a product will be easier to specify the needs via functional requirement. With the nature of interacting with user via conversation, chatbot can be used as a conversational recommender system. In this work we will be developing chatbot as a conversational recommender system based on user functional requirement. The developed system will be evaluated using usability testing method.
