In earlier days the authors were asking their friends or relatives for their opinions regarding products which they want to purchase from the merchants. But now a day's E-commerce is gaining more and more popularity. Whatever query they are having, they can find its answer from World Wide Web. Merchants are also selling their products online and at a same time they are asking customer's review regarding products, which customer has bought.
