Summary

The word-of-mouth diffusion has been regarded as an important mechanism to advertise a new idea, image, technology, or product in online social networks (OSNs). In this talk, I will introduce our recent research work on content propagation in Pinterest, a popular OSN where people can collect, organize, and share images that they find interesting. We propose models to predict whether a content will be (a) popular in terms of the volume of its cascade, or (b) viral in terms of the structural virality. I will also briefly introduce our work on conversation cascade in Reddit. We believe our work can provide an important insight for for content providers, OSN operators, and marketers in predicting popular or viral content diffusion.
