The Anti-Social Web WWW 2012
The 2nd Joint WICOW/AIRWeb Workshop on Web Quality in conjunction with WWW 2012 in Lyon, France on April 16, 2012

News: WebQuality 2013 is planned to be organized at WWW 2013


The objective of the workshop is to provide the research communities working on web spam, abuse, credibility, and reputation topics with a survey of current problems and potential solutions. It will present an opportunity for close interaction between practitioners who may have focused on more isolated sub-areas previously. We also want to gather crucial feedback for the academic community from participants representing major industry players on how web content quality research can contribute to practice.

On one hand, the joint workshop will cover the more blatant and malicious attempts that deteriorate web quality such as spam, plagiarism, or various forms of abuse and ways to prevent them or neutralize their impact on information retrieval. On the other hand, it will also provide a venue for exchanging ideas on quantifying finer-grained issues of content credibility and author reputation, and modeling them in web information retrieval.
