Comparison and evaluation of online products based on a web application

Abstract

In recent years, e-commerce has developed rapidly and this leads to the appearance of many e-commerce websites. Especially, e-commerce is a young industry in Vietnam, which is in the ideal development momentum. In particular, more than 2 years of the Covid epidemic have changed the shopping habits of the majority of consumers from direct shopping to e- commerce. The number of e-commerce sites so far is very large, leading to the market being diluted and new e-commerce sites being difficult to reach users. Most e-commerce websites have their own special features to attract users such as marketing, making beautiful and easy to-use interfaces, offering many attractive incentives, etc... But what if the user buys a product from an e-commerce site and then finds out that they can buy the same product at another e- commerce website with a more attractive price and offer, the user will feel a loss. and do not return to the website again. So for commerce sites to be more accessible to customers, I came up with the idea to develop the functions of comparing and evaluating products from many different e-commerce websites. In this thesis, I propose a solution for developing the functions of comparing and evaluating products based on web applications. The solution includes the following steps, collecting data from three or more e-commerce websites, analyzing collected data, and showing data on a website.
