The Arg Lab, directed by Dr. Collin F. Lynch, is focused on developing innovative and effective educational interventions and educational data mining; on deploying those technologies to support students, educators, and educational institutions in rich complex domains such as Argumentation, software development, and design; and on analyzing the real-world impact of those technologies to develop appropriate policies that enhance their utility while safeguarding the rights of students, educators, and communities. The lab studies rich graph-mining techniques to handle heterogeneous relational data; text mining for the extraction of argument structures; and social network analysis for online learning.
