Twitter is the most popular social media platform on the internet and offers users the opportunity to express their opinions on a variety of topics, including news, current events, cabaret and other topics. One such topic is opinions on mental health. Issues on Health The only significant problem in the world is mental. A decrease in the number or rate of mental illnesses can be successfully eliminated when society contributes to not discriminating against sufferers. However, there are many different opinions on Twitter from different internet users, and one of the most prominent is the opinion on mental health. Therefore, it is necessary to conduct a basic analysis of public opinion to explain and provide new information on certain topics related to mental health, the methods used are Naïve Bayes Clasifier and K-Nearest Neighbors (K-NN) algorithms. A total of 5000 data were taken using the twitter API with the keyword "Mental Health". Starting from the classification of positive or negative opinions, data cleansing, preprocessing, until the final result is obtained. Then calculated into two different algorithms to compare, the algorithms used are Naïve Bayes Classifier and K-Nearest Neighbors (K-NN) with the aim of finding the best accuracy. The Rapidminer Version 7.1 application is also used to facilitate the author in processing data. The highest result of this research is the Naïve Bayes algorithm with an accuracy value of 98.3%, precision 79% and recall 87.17%. date: 2022-03-10 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://digilib.uin-suka.ac.id/id/eprint/58412/1/21206051002_BAB-I_IV-atau-V_DAFTAR-PUSTAKA.pdf format: text language: id identifier: https://digilib.uin-suka.ac.id/id/eprint/58412/2/21206051002_BAB-II_sampai_SEBELUM-BAB-TERAKHIR.pdf identifier: Tachiyya Nailal Khusna, NIM.: 21206051002 (2022) KOMPARASI ALGORITMA NAÏVE BAYES CLASSIFIER, K-NEAREST NEIGHBOR (KNN) DAN DECISION TREE UNTUK MENGANALISIS SENTIMEN MASYARAKAT TERHADAP KESEHATAN MENTAL PADA MEDIA SOSIAL TWITTER.
