 Argument mining is a subfield of data mining, or text mining (and computational linguistics). It uses software and algorithms that automatically process texts looking for argument structures — for premises, conclusions, argumentation schemes, and extended webs of argument. The texts studied include legal documents , on-line debates, product reviews, academic literature, user comments on proposed regulations, newspaper articles and court cases, as well as dialogical domains.  ARG-tech,  the Centre for Argument Technology, has played a central role in studies of this sort.
