A tutorial about generative models for discussion threads in online forums

Generative models of online discussion threads

Welcome to our tutorial on generative models of online discussion threads. The tutorial is based on the survey:

• Aragón, P., Gómez, V., Garcı́a, D. & Kaltenbrunner, A. Generative models of online discussion threads: state of the art and research challenges. J. Internet Serv. Appl. 8, 15 (2017). DOI 10.1186/s13174-017-0066-z

The notebook for the hands-on session is based on the genthreads R package developed by Alberto Lumbreras and then extended in collaboration with Matteo Manca. The purpose is to provide tutorial attendeeds with computational and statistical tools to:

• Represent data from online discussion threads using array structures
• Visualize online discussion threads as tree networks
• Apply different generative models of online discussion threads:
  • Gómez et al. 2013
  • Aragón et al. 2017
• Validate generative models through structural properties:
  • Degree
  • Subtree (cascade) size
  • Depth
