Introduction:
In the era of online commerce and social media, user-generated reviews have become a crucial part of decision-making for consumers. However, the presence of fake reviews has become a significant issue, as they can mislead consumers and distort the reputation of businesses. Detecting fake reviews manually is a time-consuming and challenging task, which has led researchers to explore automated methods using natural language processing (NLP) and machine learning techniques.

Thesis Overview:
Fake review detection using natural language processing (NLP) and machine learning techniques has gained significant attention in recent years due to the prevalence of fake reviews in online platforms. This thesis aims to provide a comprehensive analysis of existing methods for fake review detection and propose an improved approach using advanced NLP and machine learning algorithms.
The literature review will cover various approaches for fake review detection, including sentiment analysis, feature extraction methods, data preprocessing techniques, and evaluation metrics. The research methodology section will detail the data collection, preprocessing, feature extraction, model selection, training, evaluation, and parameter tuning processes.
The discussion of findings will include a performance comparison of different algorithms, feature importance analysis, error analysis, interpretability of the models, generalization to different domains, scalability, and computational efficiency of the proposed method. Ethical considerations will also be addressed.
In conclusion, this thesis will summarize the findings, discuss the contributions of the study, suggest implications for researchers and practitioners, and propose future research directions in the field of fake review detection using NLP and machine learning.
