Before revision:  With the proposed computational framework, we derive significant findings, e.g. the percentage of females in both hoarding and anti-hoarding groups is higher than that of the general Twitter users . Furthermore, using topic modeling, we investigate the opinions expressed about the hoarding behavior by categorizing these topics according to demographic and geographic groups.
