Trust, Risk, Reputation and Recommendation on the Web

Riga, Latvia, September 7, 2009

Call for Papers

Recent years have witnessed the transition of the Web from an information repository service to a social and business platform. New, unprecedented services are available on the Web that capitalize on the social aspects of user communities. Crowd-sourcing, user-generated content, folksonomies, social computing, are all examples of services that were made possible by the recent shift in application design paradigms. Unfortunately, pseudoanonymity of Web users combined with strong financial incentives encourage many users to perform malicious activities. These activities range from relatively harmless (e.g. trolling), through irritating (e.g. spamming), up to criminal (e.g. online auction fraud). In order to protect the community of users from malevolent wrong-doers, new tools and techniques need to be developed. In particular, trust, risk and reputation management systems must be designed and implemented to enable the emergence of fairness in Web environments. In parallel with user protection, user accessibility to high quality sources in Web environments must be granted. Recommendation systems are the primary tool to allow users to access most valuable sources.

The objective of the workshop is to create a common space for researchers and practitioners of trust, risk and reputation management to collaborate, exchange and discuss ideas, case studies, and solutions. The management of trust, risk and reputation, as well as recommendation engines, are ubiquitous in Web environments. They apply to webpages, blogs, social networks, Internet forums, P2P networks, online auction markets, and business to business markets, to name a few. Hence, workshop topic list is very broad and includes (not exclusively):

  • ranking algorithms for social networks
  • anomaly detection in social networks
  • spam detection in social networks
  • personalization of interaction in social networks
  • community detection and evolution
  • webpage ranking
  • link analysis
  • link and webpage spamming
  • ranking relational data
  • P2P ranking and spamming
  • fairness in P2P networks
  • blog search, ranking, and retrieval
  • spam detection in blogs
  • trust and reputation management in the blogosphere
  • social role discovery in Internet forums
  • reputation of Internet forum community members
  • trust and reputation in online auctions
  • risk analysis and risk propensity
  • recommendation systems
  • group recommendations

The main objective of the workshop is to create a community of researchers around trust, risk and reputation management in Web environments. The workshop is aimed primarily at young and prospective researchers to allow them to exchange ideas, tie professional relationships, and collaborate scientifically. Also, we welcome the input from commercial parties, demonstrations and in-progress research reports.

The workshop is open to all registered ADBIS participants. We invite researchers, practitioners, and PhD students who are interested in workshop subjects to participate and contribute to the discussion.
