MODEL TERBARUKAN HYBIRD CNN DAN LEXICON-BASED UNTUK MENDETEKSI SENTIMEN PUBLIK TERHADAP DANANTARA
Abstrak
Danantara merupakan dana kekayaan negara yang mendapat perhatian luas di media sosial, termasuk di “X”. Berbagai opini publik tentang danantara muncul, baik dalam sentimen positif maupun negatif. Untuk memahami persepsi masyarakat secara lebih akurat, diperlukan metode analisis sentimen yang efektif. Metode Lexicon-Based sering digunakan tetapi memiliki keterbatasan dalam menangkap konteks, sementara Convolutional Neural Network (CNN) mampu mengenali pola dalam teks tetapi membutuhkan banyak data. Maka dari itu penelitian ini bertujuan untuk mengembangkan model hybird CNN dan Lexicon-based guna meningkatkan akurasi analisis sentimen publik terhadap Danantara. Data akan dikumpulkan dari media sosial “X” menggunakan metode scraping atau API, kemudian melalui proses preprocessing sebelum dianalisis menggunakan pendekatan hybird. Evaluasi model dilakukan dengan membandingkan performa CNN, Lexicon-based dan hybird model menggunakan metrik seperti akurasi, precision, recall dan F1-Score. Hasil peneltian ini memberikan model yang lebih akurat dalam memahmi opini publik serta memberikan wawasan bagi pemangku kebijakan dalam merancang strategi komunikasi yang lebih efektif dengan tingkat akurasi sebesar 86%. Selain itu peneliti juga akan berkontribusi dalam pengembangan Natural Languange Processing (NLP) dana analisis sentimen berbasis deep learning.
