The 4th 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; the 2nd Conference in Lausanne, Switzerland; and the 3rd Conference in New York, USA. 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 4th 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.

For the first time, ACM RecSys 2010 had more than 200 submissions. Of 129 full paper submissions, 25 were accepted (19.4%) for oral presentation at the conference. Of 78 short paper submissions, 32 were accepted (41.0%) for poster presentation. In addition, we introduced a new track for submission of demos and case study reports, which have also been presented at the poster session.
