CALL FOR PROPOSALS
===================================================

RecSys 2011 is pleased to invite proposals for workshops to be held in conjunction with the conference. The goal of the workshops is to provide additional venues for presenting research on topics of interest and an informal forum to discuss research questions and challenges.

We encourage proposals for a wide range of workshops, including but not limited to:

* One day mini-conferences on specialized topics; such workshops may have their own paper submission and review processes.
* Working group meetings organized around a specific problem; such workshops may wish to ask participants to submit a short white paper or position statement.
* Mini-competitions or challenges around selected topics with individual or team participation.

We welcome proposals for half-day and full-day workshops.

We encourage you to contact us in advance (werner.geyer@us.ibm.com,
riedl@cs.umn.edu) with workshop ideas; we will work with prospective workshop organizers to help them design successful proposals. We actively encourage both researchers and industry practitioners to submit workshop proposals.
