1. Fake reviews and inflated ratings is a big concern for e-commerce platforms. A fake review is a review written by someone who has not actually used the product or given manipulated review to get refund or the offered incentive. (a) Suppose you aim to build a model to identify fake reviews. Unfortunately, we do not have any existing labelled dataset for this problem. We also lack sufficient human annotators to label big enough dataset for supervised learning. • Design a partially/fully automated solution to create labelled dataset. • How would you ensure the quality of the data? • Discuss the pros and cons of the proposed solution. (b) Design an approach to flag fake reviews. Clearly demonstrate all the modules using a diagram.

System Model Approaches

The systems model approach is a process-oriented representation that emphasizes the impact or flow of information between modules. The multidisciplinary study of the use of models to design and create systems in business and IT development is known as systems model approach. It models how processes interact and what these processes do, but it does not go into detail about how these processes are implemented. Functional decomposition may be utilized to enhance the models employed in this technique, and they can be coupled to requirements models for additional system partitioning.
