Tracing Community Genealogy: How New Communities Emerge from the Old

This repo has dataset and code for visualization of paper : Tracing Community Genealogy: How New Communities Emerge from the Old

Dataset present in data directory :

data.csv and data-full.csv consists of children and parent subreddits with weights (indicating 100 early adopters)
data.csv has minimum weights higher than 0.04 with 90K adoptions.
data-full.csv has minimum weights higher 0.02 with 390K adoptions.
We use data-full.csv for visualization.

Abstract

The process by which new communities emerge is a central research issue in the social sciences. While a growing body of research analyzes the formation of a single community by examining social networks between individuals, we introduce a novel community-centered perspective. We highlight the fact that the context in which a new community emerges contains numerous existing communities. We reveal the emerging process of communities by tracing their early members' previous community memberships.
