	Special Session on Social Media Retrieval and Filtering (SMRF)
				at the
       9th International Workshop on Content-Based Multimedia Indexing
                       13-15 June 2011, Madrid, Spain

Nowadays, an ever increasing amount of multimedia content is available
on content sharing websites such as Flickr, Youtube or Facebook. This
content consists of text and multimedia data, enriched with additional
metadata (annotations, comments, tags, etc.). In addition, semantic
relationships between content and content sharers can be inferred by
considering the structure of the social content sharing websites.
However, this social factor has hardly been studied in the information
retrieval and recommendation domain. This special session aims at
state-of-the-art research approaches that address the underlying
social structure for retrieval and filtering of multimedia content.

Scope and Topics
We are interested in works in multimedia retrieval and filtering on
the Social Web, including, but not limited to the following research

    * Analysis, indexing, search and retrieval of social media content
    * Scalable indexing and structure of social media content
    * Semantic-based retrieval and filtering of social media content
    * Learning, personalization, content adaptation, and relevance
fedback in social media systems
    * Personal multimedia content management in social media systems
    * Social and content-based multimedia recommendation
    * Summarization, organization, browsing, and exploration of social
media content
    * User interfaces for management, presentation and visualization
of social media content
    * Social media data indexing, search and retrieval in mobile environments
    * Context-awarenes in social media systems
