International Workshop on Recommendation and Collaboration (ReColl)
(in conjunction with IUI 2008)
Canary Islands, Spain
13 January 2008

*Topics of interest*
This workshop aims to identify emerging trends in recommendation 
technology and collaborative environments in the context of 
intelligent user interfaces. We will explore these two topics 
separately and the synergies between them.
Recommendation: In recent years, recommender technology has become 
a popular component of web-based commerce sites. With the growth 
of the social web, increasing mobility, and the rise of software 
as a service, a variety of new opportunities are opening for the 
application of recommender technology. These, and other trends, 
are driving a number of advances in this area. This workshop will 
give researchers in the area of recommender technology an 
opportunity to come together and discuss the "next generation" 
of research problems to be addressed. Emphasis will be on both the 
collaborative aspects of recommender systems, as well as other 
appropriate technologies, such as knowledge-based systems. 

*Topics that may be covered include:* 
- Applications of recommender technology 
- Hybrid recommender technologies 
- Combining social networking systems and recommender systems 
- Knowledge-based recommenders 
- Evaluation approaches 
- Intelligent and adaptive interfaces 
- Semantic web technologies and recommender systems 
- User intent and preference modeling 
- Recommendation as a service 
- Mathematical validity vs. scalability of algorithms 
- Explanations and other mechanisms to increase user confidence 

Collaboration: Modern collaborative environments enable large groups of 
users to share data and memories, different views about events, ratings 
about web sites or products, and models of user behavior. The internet, 
the World Wide Web (WWW) and modern peer-to-peer technology provide an
(infrastructure on top of which a variety of communication channels and 
collaborative environments have been established. Successful examples of 
collaborative environments include Web 2.0 content sharing systems (such 
as Flickr, YouTube and, recommender systems for products or 
other resources, peer-to-peer content sharing systems, and collaborative 
assistance systems. Design of novel interfaces for better supporting 
collaboration scenarios has been intensively studied in the Recent 
research. Our workshop reverses the common problem definition and 
poses the novel question: how can intelligent user interfaces benefit 
from user collaboration?

*Topics of discussion include, but are not limited to:*
- Combination and representation of content from different sources 
- Evidence combination for assistance interfaces 
- Interface personalization in collaborative environments 
- Summarization of content from different sources 
- Collaborative methods for personalized web search and retrieval 
- Combination of decision models from multiple users
- Collaborative methods for Web 2.0 applications 
- Collaborative recommender systems 
- Security and privacy aspects of collaborative interfaces 

*Submission instructions*
Authors are invited to submit original, unpublished contributions that are 

not being considered for publication or presentation in any other forum. 
ReColl 2008 submissions should be prepared according to the standard 
publications format: Submissions must be in PDF format. All papers must be 

submitted electronically via the Workshop Review site. You can continue to 

upload revised copies up until the deadline. 
Submission formats include research papers (up to 8 pages), 2-page 
position papers, or 1-2 page descriptions of demonstrations. ReColl does 
use blind review, so please include authors' names and affiliations on 
submission. Submissions will be judged according to their scientific 
and evaluated on significance, originality, technical quality, and 
At least one author per accepted submission is required to register for 
2008 at the full rate and to present the contribution in the workshop. All 

accepted submissions will be published in the CEUR Workshop Proceedings 
(, ISSN 1613-0073) and therefore indexed by services such as 

*Important Dates*
