An Efficient Ensemble Approach for Fake Reviews Detection
Opinion spam on online restaurant review sites is a major problem as the reviews influence the users’ choice to visit or not a restaurant. In this project, we will address the problem of detecting genuine and fake reviews in restaurant online reviews. We propose a fake review detection technique comprising data preprocessing, detection and ensemble learning that learns the reviews and their features to filter out the fake reviews. Initially, decision trees, random forests and logistics regression algorithms will be implemented. Finally, a hybrid ensemble model from the two classifiers is built to detect genuine and fake reviews. Precision and recall will be used for performance measures.
The proposed methodology consists of the following steps:
1. Data Collection
2. Data preprocessing and preparation
3. Data summarization
4. Training model (Adaboost, Random Forest, and Logistic Regression classifier)
5. Grid Search Algorithm for Hyperparameters Optimization
6. Performance evaluation (Precision-Recall, F1-score)
1. This project is research-oriented and based on machine learning methods. It will help the researcher to find out the more optimal solutions to this problem.
2. Reviews are considered one of the important aspects of different online platforms. The quality of reviews also plays an important role in certain purchases on an online system. Therefore, different scientists have devised different strategies to detect fake reviews from the provided dataset. Moreover, detecting fake reviews also aids to identify fake accounts. In this project, we have successfully applied an ensemble learning approach to detect fake reviews which will useful for online customers and restaurants.
Because this project is based on research, so we will use a confusion matrix for evaluation. Precision, recall and F1-score will be measured for each algorithm. Also, we will publish a research paper in an impact factor journal.
