Abstract

Google Play Store adalah tempat berbagai macam aplikasi tersedia, baik berbayar ataupun tidak. Halaman Google Play Store menjadi tempat pengguna aplikasi untuk menyampaikan pendapat, ulasan dan penilaian. Ruang Guru, Zenius dan Quipper tersedia di platform tersebut. Data pada ulasan, menjadi sangat bermanfaat untuk dianalisa. Analisa dilakukan dengan menggunakan sentimen analisis dan algoritma SVM. Data diperoleh dengan menggunakan teknik scraping data, dengan menggunakan bantuan library google-play-scraper. Proses web Scraping, dibagi menjadi 3 tahap yaitu Fetching, Extraction, dan Transformation. Data dikumpulkan sebanyak 30.000 data, yang dibagi menjadi 10.000 data Ruang Guru, Zenius dan Quipper. Peneltian diawali dengan Tahap preprocesing data meliputi normalisasi, case folding, cleaning, tokenizing, dan  Stopword. kemudian data dibagi menjadi 90% data latih dan 10% data uji. Data latih diberi label dengan nilai 1, 0, dan -1. Nilai 1 berarti positif, nilai 0 berarti netral dan -1 berarti negatif. Hasil sentimen klasifikasi menggunakan SVM, menunjukkan bahwa Ruang Guru memiliki nilai positif tertinggi dibandingkan Zenius dan Quipper. Akan tetapi, respon pengguna sama-sama memberikan nilai positif untuk aplikasi tersebut. Nilai akurasi dari penelitian menunjukkan bahwa, data Klasifikasi sentimen dengan SVM, mempunyai akurasi rata-rata untuk Ruang Guru sebesar 99%, Zenius sebesar 96%, dan Quipper sebesar 82%.

Abstract

Consumers believe that restaurant reviews are very important when choosing a restaurant. Due to the fact that reviews have become one of the most effective ways to influence customer decisions, research that has been done on restaurant customer reviews is about sentiment analysis. Previous studies have only used sentiment analysis at the sentence or document level, while a better level uses Aspect-Based Sentiment Analysis (ABSA), or a type of aspect-based sentiment analysis. LSTM is a variant of RNN that stores long-term information in memory cells. Use of global max pooling to reduce output resolution features and prevent overfitting. In addition, the optimization method used by Adam Optimizer is an adaptive learning rate optimization algorithm specifically designed to train deep neural networks. This study aims to classify restaurant customer opinions based on aspects (food, place, service, and price) based on restaurant customer reviews on Indonesian-language TripAdvisor with LSTM and global max pooling for sentiment classification (negative, half negative, neutral, half positive, positive). The results of this study indicate that the ABSA in restaurant customer reviews for sentiment classification accuracy is 78.7% and the aspect category accuracy is 78%, both are interconnected and can help understand restaurant customer opinions on TripAdvisor.
