ABSTRACT: 
Internet is currently the most popular source of information. But with the overabundance of online content much of Web content cannot be trusted. In this tutorial we will outline existing research dedicated to website credibility evaluations – pointing out main research trends and discussing major findings in this area so far.  We would also like to demonstrate functioning of Reconcile (http://www.reconcile.pl) system which is an open platform developed by Social Informatics research team from Polish-Japanese Institute of Information Technology. Reconcile is an online tool designed to  support credibility evaluations of Web content.

The tutors would like to kindly ask all prospective participants to register at http://sourceforge.net/projects/reconcile2011/ in order to get access to Reconcile documentation.

OUTLINE:

  • Introduction and basic definitions (information credibility, information controversy)
  • Factors affecting website credibility evaluations (sites’ and users’ features)
  • Supporting web credibility evaluations (user expertise, crowdsourcing systems, certifications)
  • How to measure credibility – discussion of aggregation measures
  • Reconcile system demonstration and case study results
