Spam detection
A sophisticated system is built to detect spam reviews. Detection process involves two phases
- Logically detecting if user has reviewed multiple times on the same product
- Machine learning classification model (using Tensorflow lite) is used to analyze text and classify review into truthful or deceptive. Dataset is downloaded from Kaggle
If a review is detected as spam in both the phases, then review is confirmed to be spam and Alert Notification is show to admin. If review is detected as spam in anyone of the phase, then review is marked as potential spam and admin is notified.
