We are pleased to invite you to participate in this premier annual event on research and applications of recommender technologies.

The 5th ACM International Conference on Recommender Systems builds on the success of the Recommenders 06 Summer School in Bilbao, Spain and the series of four successful conference events from 2007 to 2010 in Minneapolis (2007), Lausanne (2008), New York (2009) and Barcelona (2010).

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 5th International conference will promote the same close interaction among practitioners and researchers. Published papers will go through a full peer review process. The conference proceedings, which are available both as bound volume and via the ACM Digital Library, are expected to be widely read and cited.

In addition to a regular technical program, there will be several tutorials covering the state-of-the-art of this domain, different workshops, a doctoral consortium, and an industrial program comprising of panel discussions and a practice/industry-paper track. We also expect to have keynote speakers who will address the major applications of recommendation technologies in industry. « less
