This repository contains datasets with online conversation threads collected and analyzed by different researchers. Currently, you can find datsets from different news aggregators (Slashdot, Barrapunto) and the English Wikipedia talk pages. Slashdot conversations (Aug 2005 - Aug 2006) Online conversations generated at Slashdot during a year. Posts and comments published between August 26th, 2005 and August 31th, 2006. For each discussion thread: sub-domains, title, topics and hierarchical relations between comments. For each comment: user, date, score and textual content.
