Introduction

E-commerce platforms such as Amazon, AliExpress, and Shopify allow users to upload items they would like to sell. Thousands of vendors use them to connect with potential consumers.

But not everything can or should be sold there, and it’s the responsibility of the platforms to monitor what’s being sold on them. In this article, you will learn how multinational online shopping company AliExpress does just that.

What is item moderation?

Item moderation for e-commerce is a classification problem. After looking at pictures of the product, its description, and the price, we need to decide if it is suitable for sale on the platform.

AliExpress has a few categories they classify items into:

  • OK. Products without display restrictions. They can be sold and displayed everywhere.
  • RESTRICTED. Products restricted to display. They can only be shown on direct request.
  • ADULT. Adult products related to sex. They have a separate category since there is a unique logic for them (blair[JF1] , age confirmation, display only by request).
  • PROHIBITED. Products prohibited from sale according to the country’s laws or company policy. They can’t be shown anywhere or sold at all.
  • SUSPECT OF FRAUD. Products with unreasonably high or low prices or without a clear description.

What makes item moderation such a challenge?

If you want to decide on a product category, you often need to understand the context. You have to know where items are sold before you can adhere to local laws. Below you can see examples of different gift vouchers that are sold in Aliexpress in China but would not be allowed on the platform in Russia.
