RecSys'09 Workshops (Oct. 25)

Workshop 1: Recommender Systems and the Social Web

The Social Web has been enjoying huge popularity in recent years, attracting millions of visitors on sites such as Facebook, Delicious, YouTube. We are no longer mere consumers of information, but we also actively participate in social networks, upload our personal images, share our bookmarks, write web logs and annotate and comment on the information provided by others. This Social Web provides huge opportunities for recommender technology and in turn recommender technologies can play a part in fuelling the success of the Social Web phenomenon as new application reas for RS technology emerge, new sources of knowledge for RS become available, and richer user Web interfaces are possible.

The goal of this workshop is to explore, discuss, and understand new opportunities for recommender systems and the Social Web.

Workshop 2: Open Source Recommender System Software (cancelled!)

Workshop 3: Workshop on Context-Aware Recommender Systems (CARS-2009)

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;

Large-scale context-aware recommender systems;

Evaluation of context-aware recommender systems.

Workshop 4: 1st International Workshop on Recommendation-based Industrial Applications

Recommender systems help users to deal with large information systems by assisting them in their decision-making processes. Recommender systems have been applied to real industry software systems very successfully in a variety of domains. One of the most exciting characteristics of recommender systems is that they combine interest from the industry and businesses while posing very interesting research challenges. This workshop aims at bringing the gap between academic researchers and industry practitioners on the area of Recommender Systems. We are interested both in research work that faces real industry problems, and in industry cases that create research challenges. A main goal of the workshop is to promote the discussion among the academic researchers and industry practitioners, so the format of the workshop will combine formal paper presentations with open discussion sessions.
