Spreading processes, such as rumor and epidemic spreading, can be naturally seen as dynamic processes in complex networks. Individuals are represented by vertices and their relationship is represented by edges of a network. However, social networks can be too large to measure or even have an unknown size, making it hard to obtain a complete picture of them. Consequently, there are cases when sampled networks must be used instead of the real one. In this project, we intend to compare sampling techniques in order to learn which method is the best when dealing with spreading processes.
