Short Bio.

Woo Seong Jo is a postdoctoral researcher at the Northwestern Institute on Complex Systems (NICO) and the Kellogg School of Management at Northwestern University. His research subjects cover various aspects of computational social science, complex networks, and modeling of complex systems with large-scale datasets. Recently, he focuses on understanding failures of a team using various datasets. He received his Ph.D. in physics from Sungkyunkwan University in 2018.

  • Visualization of Jokbo data
  • National Research Foundation (2015)

    I made the web site to visualize analysis results of Jokbo. This site visualize how the number of brides’ families are changed in time for given gloom’s family. As well as analysis of marriage patterns, the site shows alluvial diagram in time that visualize the trace of the top 10 families in people who passed the examination for high-ranked officer in Joseon Dynasty. I used D3.js library for visualization and set up web server in our lab.

  • Collection and analysis of social data
  • Samsung Economic Research Institute (2013-2014)

    In this project, I made crawling program to collect social data from web service and analyzed data. I constructed network using social connections and users’ attributes to find the features of targets. Our approach worked well to extract the latest features which were known from spreading rumors. I set up the service for collection and analysis of data.
