Influence Maximization in Real-World Closed Social Networks

Understand

In the last few years, many closed social networks such as WhatsAPP and WeChat have emerged to cater for people's growing demand of privacy and independence.

• In a closed social network, the posted content is not available to all users or senders can set limits on who can see the posted content.
• Under such a constraint, we study the problem of influence maximization in a closed social network.
• It aims to recommend users (not just the seed users) a limited number of existing friends who will help propagate the information, such that the seed users' influence spread can be maximized.
