Penelitian ini mengeksplorasi deteksi ulasan palsu secara online menggunakan berbagai representasi data dan model deep learning, dengan menemukan bahwa kombinasi representasi data melalui teknik fusi data secara signifikan meningkatkan akurasi prediksi.
Penelitian menggunakan pendekatan eksperimental dengan mengevaluasi berbagai representasi data (emosi, document embedding, n-grams, noun phrases) pada model deep learning (BiLSTM, LSTM, GRU, CNN, MLP) menggunakan empat dataset publik. Selanjutnya, teknik fusi data awal dan akhir diterapkan untuk menggabungkan representasi dan model terbaik guna meningkatkan performa prediksi secara keseluruhan.

Many different Machine Learning based solu- tions have been proposed, using various data representations such as n-grams or document embeddings. In this paper, we first explore the effectiveness of different data representa- tions, including emotion, document embedding, n-grams, and noun phrases in embedding for- mat, for fake reviews detection. We evaluate these representations with various state-of-the- art deep learning models, such as a BILSTM, LSTM, GRU, CNN, and MLP. Following this, we propose to incorporate different data repre- sentations and classification models using early and late data fusion techniques in order to im- prove the prediction performance. The exper- iments are conducted on four datasets: Hotel, Restaurant, Amazon, and Yelp. The results demonstrate that a combination of different data representations significantly outperforms any single data representation.
