With the further popularity of online shopping, people can buy the goods they want on online platforms without leaving home. However, due to the asymmetry of information, it is difficult for consumers or companies to compare the advantages and disadvantages of the same goods on different e-commerce platforms. This paper uses the word cloud method for text mining and Python to crawl and analyze customer reviews of the same product on two e-commerce platforms, which are Taobao and Jingdong, in order to compare the similarities and differences of the same product on different platforms. Through the comparison, we found that customers on the Jingdong platform think that the Jingdong platform provides good logistics services, while customers who consume on Taobao more often think that the products on that platform have high cost performance.
