Fake review detection for online marketplaces using natural language processing – Complete Phd and Masters Thesis

[ad_1]

Introduction

With the rise of online marketplaces, the importance of customer reviews has increased significantly. Reviews play a crucial role in helping consumers make informed purchasing decisions. However, with the increase in fake reviews, the credibility of these online reviews has come under scrutiny. Fake reviews are created with the intention of deceiving consumers and manipulating their purchasing behavior. Detecting and filtering out fake reviews is essential to maintain the trustworthiness of online marketplaces.

Natural Language Processing (NLP) techniques have been widely used in various applications, including fake review detection. NLP involves the use of computational techniques to analyze and understand human language. By applying NLP techniques, researchers and practitioners can develop algorithms to automatically detect fake reviews with high accuracy.

This thesis aims to investigate fake review detection for online marketplaces using natural language processing. The study will explore various NLP techniques and apply them to detect fake reviews in online platforms. By developing effective fake review detection algorithms, this research aims to contribute to the integrity and reliability of online reviews.
