SocialSensor is an EU initiative that aims to collect, and aggregate big streams of social media data and multimedia to discover trends, events, influencers, and interesting media content.

In this context, SocialSensor has developed a new framework for enabling real-time multimedia indexing and search in the Social Web. Moreover, it has moved beyond conventional text-based indexing and retrieval models by mining and aggregating user inputs and content over multiple social networking sites. Social Indexing incorporates information about the structure and activity of the users’ social network directly into the multimedia analysis and search process.
