The two facets of a cascade Structural Temporal Who influenced whom to spread the content How many shares are there at any point in time (Day/Hour) 0! 6! 12! 18! 24! 30! 0! 2! 4! 6! 8! 10! Number of shares! Days after publishing!
Paper TOC Our paper answers the following questions about cascades: 1. What are they? definitions .. 2. What is their significance? 3. How cascade networks are constructed? 4. What are the effects of the content type and the available data on cascade construction approaches? 5. What features we can use to analyse cascades? i.e., how can we quantify cascades?

Why analysing cascades is important? 1. A proxy to unravel the way information is spread on the Web 2. Estimate influence and homophily between users 3. Estimate the value of the content 4.They are better indicators of users’ interest and trust networks 5.Explain social network evolution
Wrapping up .. • Cascades matter! • Platforms & content types matter! • They affect how data about cascades can be collected, prepared and analysed • Research tasks are affected (challenged!) by them
