In order to help buyers with their purchasing decision, this has given research community to work on the effectiveness in detecting unfair rating on the online system. In this report, it will discuss two existing detecting unfair rating models which are BRS and TRAVOS. To further help the researcher in these areas to evaluate the effectiveness of the detecting models, it will also be discussed on the development of a marketplace simulation where researcher can run a virtual marketplace simulation where buyers and sellers can do transactions.
