3rd ACM Conference on Recommender Systems

New York City, NY, USA, 22nd-25th October 2009

The 3rd ACM Conference on Recommender Systems has been built on the success of “Recommenders 06 Summer School” in Bilbao, Spain; the 1st Conference in Minneapolis, USA; and the 2nd Conference in Lausanne, Switzerland. In these events many members of the practitioner and research communities valued the rich exchange of ideas made possible by the shared plenary sessions. The 3rd conference promoted the same close interaction among practitioners and researchers, reaching a wider range of participants including those from Europe and Asia. Published papers went through a full peer review process. The conference proceedings are widely read and cited.

In addition to a regular technical program, there were tutorials covering the state-of-the-art of this domain, a doctoral consortium, and an industrial program comprising of keynote speakers and practice/industry-paper tracks.

With 187 submissions the 2009 ACM RecSys has continued to grow at a fast rate of over 50%. Authors from 35 different countries from all over the world submitted their papers. After the program committee consisting of 78 researchers finished a thorough scientific review process in two rounds writing almost 700 reviews, less than 19% of the long submissions have been accepted, the overall acceptance rate for long and short papers is less than 40%. Besides a deepened interest in algorithms for recommender systems, this year tags and social networks, privacy and security and trust attracted the most attention by authors.
