Fake Reviews Detection through Analysis of Linguistic Features
This addresses the issue of counterfeit reviews for businesses and consumers, but it is incremental as it builds on existing methods with new feature analysis.
The paper tackled the problem of detecting fake online reviews by analyzing linguistic features, achieving high accuracy in classification using machine learning algorithms.
Online reviews play an integral part for success or failure of businesses. Prior to purchasing services or goods, customers first review the online comments submitted by previous customers. However, it is possible to superficially boost or hinder some businesses through posting counterfeit and fake reviews. This paper explores a natural language processing approach to identify fake reviews. We present a detailed analysis of linguistic features for distinguishing fake and trustworthy online reviews. We study 15 linguistic features and measure their significance and importance towards the classification schemes employed in this study. Our results indicate that fake reviews tend to include more redundant terms and pauses, and generally contain longer sentences. The application of several machine learning classification algorithms revealed that we were able to discriminate fake from real reviews with high accuracy using these linguistic features.
