Trustworthiness of User Feedback in the Context of E-Commerce

Due to the tremendous development in the field of web technology doors have opened for several e-commerce websites to market and sell products online. They also provide opportunity for the users to post opinions or reviews based on their experience in buying the products. So the trend has been set by buyers to go through reviews before buying any products and make decisions accordingly. But the main question that comes into picture is whether these reviews are believable or not. Nowadays due to review’s capacity to change buyer’s decision, there are people or firms whose only job is to write spam reviews either to falsely defame or to promote a product which is unethical. This paper mainly deals with a trust system through which the genuineness of the review is checked, which is based on the behavior of its reviewer towards other pre-fabricated reviews. Only those proved trustworthy can publish their reviews in the webpage so that those reviews are considered for opinion mining.
