	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 topics:

    * 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
