                         2nd CALL FOR PAPERS
       3RD WORKSHOP ON CONTEXT-AWARE RECOMMENDER SYSTEMS (CARS-2011)
  (In conjunction with the 5th ACM Conference on Recommender Systems)
               October 23, 2011 - Chicago, USA

                    http://www.cars-workshop.org

=======================================================================

Update: The workshop organizers are planning to organize a special issue
on this topic in an ISI-rated journal.


This workshop builds upon the success of the previous two Workshops on 
Context-Aware Recommender Systems held in New York in October 2009, and 
Barcelona September 2010, which brought together an international group of 
researchers to explore the importance and use of contextual information in 
recommender systems as well as to discuss new research directions.

The importance of contextual information has been recognized by researchers
and practitioners in many disciplines, including e-commerce personalization,
information retrieval, ubiquitous and mobile computing, data mining,
marketing, and management. While a substantial amount of research has
already been performed in the area of recommender systems, the vast majority
of existing approaches focuses on recommending the most relevant items to
users and does not take into account any additional contextual information,
such as time, location, weather, or the company of other people. Therefore,
this workshop aims to bring together researchers with wide-ranging
backgrounds to identify important research questions, to exchange ideas from
different research disciplines, and, more generally, to facilitate
discussion and innovation in the area of   context-aware recommender systems
(CARS).   In particular, topics of interest for this workshop include (but
are not limited to): 

-- Context modeling techniques for recommender systems;
-- Context-aware user modeling for recommender systems;
-- Data sets for context-dependent recommendations;
-- Algorithms for detecting the relevance of contextual data;
-- Algorithms for incorporating contextual information into recommendation process;
-- Algorithms for building explicit dependencies between contextual features and ratings;
-- Interacting with context-aware recommender systems;
-- Novel applications for context-aware recommender systems;
-- Mobile context-aware recommender systems;
-- Context-aware group recommendations;
-- Large-scale context-aware recommender systems;
-- Evaluation of context-aware recommender systems. 

In case the main topic of the paper is a challenging dataset for
context-aware recommender systems, the author(s) should describe the data
model and the main features of this dataset, and make the dataset available
for the research community. 

PAPER SUBMISSION
The length of submissions is 5 pages in the standard ACM SIG proceedings
format.  Microsoft Word and LaTeX templates for papers in ACM SIG format are
provided at: 

	http://www.acm.org/sigs/publications/proceedings-templates

All submissions must be in English and the files should be in PDF format.
Paper submissions and reviews will be handled electronically; each paper
will be evaluated by the workshop program committee based on originality,
significance, technical soundness, and clarity.  All papers must be
submitted through the CARS-2011 page on the EasyChair conference management
site (https://www.easychair.org/conferences/?conf=cars2011).

ACCEPTED PAPERS
The accepted papers will be made available on the workshop website and on 
CEUR Workshop proceedings (to confirm). Authors will present their work in 
front of the workshop audience.
The workshop will NOT request the copyright transfer from the authors;
therefore, after receiving feedback at the workshop, the authors will be
able to submit the improved versions of their papers to conferences and
journals (the workshop organizers are currently exploring the possibilities
to organize a special issue on this topic in the UMUAI journal).

IMPORTANT DATES 
Deadline for paper submission: July 25, 2011 
Notification of acceptance: August 19, 2011 
Final versions due: September 12, 2011
