IMPLEMENTATION OF VIRTUAL CONVERSATION WITH THE COSINE SIMILARITY METHOD IN TOURISM SERVICE APPLICATIONS IN EAST KALIMANTAN

Abstract

Chatbot is an application designed to communicate with machines. This communication helps users in searching for information. The information provided varies, such as information media regarding Tourism Public Services in the East Kalimantan Region. Natural Language Processing (NLP) is a branch of Artificial Intelligence (AI) that focuses on natural language processing. Natural language is language that is generally used by humans to communicate with each other. With current artificial intelligence technology, natural language can be processed into various forms, such as chatbots using methods, one of which is using Tf- Idf and Cosine Similarity. Cosine Similarity is a method for the Question Answering system by calculating the weight of each word in a question which will then be matched to the dataset. The use of this method will be applied to a chatbot system which is intended as an information medium regarding Tourism Public Services in the East Kalimantan Region, as a substitute for customer service, in addition to changing the delivery of information so that it is easy to understand. Based on tests results overall, provides a conclusion that the application built can is said to have met the requirements functionally, even though there are some cases that have not been accepted, this is caused by data that has not been used at this time, this limitation will fade as data is added by the application development team.
