Workshop on

Recommender Systems meet Databases

in conjunction with the 22nd DEXA Conference, August 29 - September 2, 2011 Toulouse, France

Call for Papers (pdf)

Recommender systems (RS) support users in personalized access to large collections of data. From a technical perspective, RS have their origins in different fields such as Information Filtering and Data Mining and they are built using a broad array of statistical methods and algorithms. E-Commerce and consumer decision support applications have been the traditional application domains of these types of systems. However, the ever-increasing plethora of information supply due to cheap storage, the web revolution and user generated content applications, fuels the need for user-centric and context-aware information access and presentation in many more database application domains. The aim of this workshop is therefore to provide a forum for discussion and presentation of latest results that are on the intersection of database and recommender systems research. Relevant topics for submissions include, but are not limited to:

·         Preference and context modeling in Databases

User and Community Modeling

Reputation and Trust Modeling

Context Modeling

·         New Database Architectures integrating Recommender Systems

Rank integration

Resource recommendations

Learning to rank

Personal and social aspects in databases

Query recommendations

Personalized privacy preserving

New data and query models involving users and contexts

Scalability issues of databases and recommender systems

·         Innovative applications of Recommender Systems in Databases

Preference elicitation from the Deep Web

Filtering based on data harvested from the Deep Web

Content-based recommendations from BLOBs

Reputation and trust management

Social recommender systems

Visual Analytics for Recommender Systems

·         Semantics in Recommender Systems and Databases

Semantic Indexing and Recommender Systems

Semantic Annotation and Recommender Systems

Semantic Deep Web and Recommender Systems

Annotation and Indexing of the Deep Web for Recommender Systems

Distributed Semantic Indexing for Recommender Systems

Filtering of the Deep Web

·         Evaluation methodologies and approaches

User-centric evaluation

Accuracy vs. error metrics

Evaluating for novelty, diversity and serendipity
