GANs for Semi-Supervised Opinion Spam Detection (2019-03-19T00:00:00.000000Z)

TL;DR

This paper proposes spamGAN, a generative adversarial network which relies on limited set of labeled data as well as unlabeled data for opinion spam detection and improves the state-of-the-art GAN based techniques for text classification.

Abstract

Online reviews have become a vital source of information in purchasing a service (product). Opinion spammers manipulate reviews, affecting the overall perception of the service. A key challenge in detecting opinion spam is obtaining ground truth. Though there exists a large set of reviews, only a few of them have been labeled spam or non-spam. We propose spamGAN, a generative adversarial network which relies on limited labeled data as well as unlabeled data for opinion spam detection. spamGAN improves the state-of-the-art GAN based techniques for text classification. Experiments on TripAdvisor data show that spamGAN outperforms existing techniques when labeled data is limited. spamGAN can also generate reviews with reasonable perplexity.
