Examination of the online reputation systems problems and provide solution

Electronic commerce communities are considered to be communities that provide opportunities for the sellers on the one hand and include threats for the purchasers on the other hand. One of the ways to reduce such threats in these open communities is to use transaction-based reputations. These pieces of reputation information may assist estimation of the trustworthiness and evaluation of the future behaviors of peer. Many of the presented reputation evaluation models for such communities are merely based upon transaction-based feedbacks. We are going to open our discussion that exclusively feedback-based reputation models are inaccurate and ineffective. Then, we will introduce parameters for the more accurate measurement of reputation, namely: feedback, credibility of feedback source, time of feedback, number and value of transaction and based on these parameters, we will offer an evaluation model and finally provide a report on all the initial experiments showing the possibility of this model.
