- 1/5 🚨 New publication alert (@socialnetworkslab.bsky.social)! Join work w/ @auzaheta.bsky.social, @cstadtfeld.bsky.social, and Viviana Amati: “Modeling the duality of content niches and user interactions on online social media platforms” www.sciencedirect.com/science/arti... #sna #bayesian #DyNAM
- 2/5 We propose a two-step framework: 📌 Hierarchical Stochastic Block Models (hSBM) — to uncover content niches from metadata 📌 Dynamic Network Actor Model (DyNAM) — to model time-stamped interactions using niche membership as a predictor
- 3/5 Our two-step approach leverages rich timestamp resolution to explore how content niche affiliation evolves and influences interactions over time. It extends Breiger’s classic concept of the duality of persons and groups to the digital context.
