SUMMARY:PostCog: A “Search Engine” Enabling Interdisciplinary Research

DESCRIPTION:Underground forums provide useful insights into cybercrime\, w
 here researchers analyse underlying economies\, key actors\, their discuss
 ions and interactions\, as well as different types of cybercrime. This int
 erdisciplinary topic of study incorporates expertise from diverse areas\, 
 including computer science\, criminology\, economics\, psychology\, and ot
 her social sciences. Historically\, there were significant challenges arou
 nd access to data\, but there are now research datasets of millions of mes
 sages scraped from underground forums. The problems now stem from the size
  of these datasets and the technical nature of methods and tools available
  for data sampling and analysis at scale\, which make data exploration dif
 ficult for non-technical users.\n\nWe introduce PostCog\, a web applicatio
 n developed to support users from both technical and non-technical backgro
 unds in forum analyses\, such as search\, information extraction and cross
 -forum comparison. The prototype’s usability is evaluated through two us
 er studies with expert users of the CrimeBB dataset. PostCog is made avail
 able for academic research upon signing an agreement with the Cambridge Cy
 bercrime Centre.\n\nZoom details: https://us02web.zoom.us/j/81692776088?pw
