Abstract
An information propagation method includes: determining a first user corresponding to to-be-propagated information, the first user being a user whose influence is greater than a preset value in an interest type network to which the first user belongs; and acquiring a user relation network that takes the first user as a starting point, and propagating the information in the user relation network by taking the first user as a starting point. The method improves efficiency and credibility of information propagation.
Claims20
A method comprising:
- collecting user behaviors of user identifications (IDs) associated with commodities, the user behaviors including recorded purchasing histories of the user IDs associated with the commodities;
- calculating similarity degrees between commodities based on similarity degrees between attributes of the commodities;
- calculating labels associated with the commodities;
- associating the user IDs with the labels based on the user behaviors of the user IDs;
- extracting multiple interest type networks from the labels;
- determining a respective first user ID from a respective interest type network of the multiple interest type networks, the respective first user ID being a user ID whose influence is greater than a preset value in the respective interest type network to which the first user ID belongs based on user behaviors of the respective first user ID associated with respective commodities relating to the respective interest type network;
- and
- establishing a respective user relation network by using the respective first user ID as a starting point and exploring a social network of the respective first user ID, the respective user relation network including one or more contacts of the respective user ID in the social network.
An apparatus comprising:
- one or more processors;
- and
- one or more memories stored thereon computer readable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:
- calculating similarity degrees between commodities based on similarity degrees between attributes of the commodities;
- calculating labels associated with the commodities;
- associating the user IDs with the labels based on the user behaviors of the user IDs;
- extracting multiple interest type networks from the labels;
- and
- determining a respective first user ID from a respective interest type network of the multiple interest type networks.
One or more memories stored thereon computer readable instructions that, when executed by one or more processors, cause the one or more processors to perform acts comprising:
- determining a first user identification (ID) according to user behaviors associated with multiple user IDs on one or more shopping websites;
- and
- acquiring a user relation network according to one or more contacts of the first user ID in a social network.
