Human social activities naturally are represented in a form of social networks. Since old ages, it has been noted the great power of the “word-of-mouth” effects, which is also called the “social influence strength”. Nowadays, the popularity of social platforms makes it easier to obtain, manipulate and utilize the power of social influence. Then, kinds of information are spread out much more quickly and widely than ever before. Thus, it raises a new problem: how to effectively utilize social influence to affect the largest number of people? This is known as the Influence Maximization (IM) problem. Furthermore, what if social influence is utilized to promote products? This is known as the Revenue Maximization (RM) problem. In this talk, some of my achievements regarding the IM and RM will be shared.
