METHOD AND SYSTEM FOR IDENTIFYING BAD COMMODITIES BASED ON USER PURCHASE BEHAVIORS
First Claim
1. A method for identifying bad commodities based on user purchase behaviors, the method comprising:
- selecting, by a user screening module, from a set of all customers received from a customer transaction system, a set of users who only perform a single shopping behavior within a specific time period;
constructing, by the user screening module, a user-commodity purchase relationship matrix based on the specifications of the commodities purchased by the set of all customers and the set of users;
calculating, by an identifying module, a probability for each of the commodities that a corresponding commodity is bad based on the user commodity purchase relationship matrix;
generating, by the identifying module, a list of bad commodities based on the identified bad commodities; and
pushing, by a pushing module, the generated list of bad commodities to a commodity intervention system.

Abstract
A method and system for identifying bad commodities based on user purchase behaviors is disclosed. In one aspect, the method includes selecting, by a user screening module a set of users who only perform a single shopping behavior within a specific time period and constructing, by the user screening module, a user-commodity purchase relationship matrix based on the set of users and specifications of the commodities purchased by all the customers. The method also includes calculating, by an identifying module and based on the user-commodity purchase relationship matrix, a probability that a commodity is bad to identify bad commodities, generating, by the identifying module, a list of bad commodities based on the identified bad commodities, and providing, by a pushing module, the generated list of bad commodities to a commodity intervention system.
