Sentimen Analisis, Naïve Bayes, KNN, Random Forest, Twitter, BPJSAbstrak
Dari sejak didirikan, BPJS terus berusaha meningkatkan kualitas pelayanan termasuk menyediakan berbagai layanan pengaduan. Selain fasilitas pengaduan yang telah disediakan oleh BPJS, media sosial seperti twitter sebenarnya dapat dijadikan sebagai tempat untuk mengumpulkan informasi yang berkaitan dengan BPJS. Berbagai keluhan maupun apresiasi terhadap pelayanan BPJS sering disuarakan melalui media twitter. Pada penelitian ini, dilakukan pengujian tiga algoritma machine learning yaitu Naïve Bayes, K-Nearest Neighbors dan Random Forest, untuk mengetahui dan membandingkan tingkat akurasi dari masing-masing algoritma tersebut dalam melakukan klasifikasi terhadap sentimen masyarakat terhadap BPJS Kesehatan melalui media twitter. Pada penelitian ini dataset diperoleh dengan melakukan scrapping menggunakan twitter API. Data yang diperoleh kemudian diseleksi dan dilakukan labeling. Dari hasil seleksi dan labeling didapatkan dataset sebanyak 150 tweet yang terdiri atas 50 tweet positif, 50 tweet negative dan 50 tweet netral yang akan digunakan dalam percobaan. Pada percobaan dengan menggunakan 90% data untuk training dan 10% data untuk testing, didapatkan tingkat akurasi sebesar 80% Naive Bayes, 67% K-Nearest Neighbors dan 87% Random Forest.Unduhan
