Social Media provide a giant pool with personal opinions and profiles, blogs, discussion forums, communities and networks which is continuously growing with exponential speed by new posts, blogs, messages, information and opinions. For human users it is completely impossible, to follow and capture this. Even when they aer merely interested to capture specific sectors of the world of social media, without computer-technical support they are lost.  

The team of Prof. Dr. Christoph Meinel investigates social media under the aspect of knowledge management. Research is focused on the challenge to generate new knowledge from the big data that are provided in the Internet by soical media. We investigate how computers can used to efficiently collect, consolidaten, and analyse all these information and data in order to generate new beneficial knowledge. Our research is quickend by the chance to have access to most recent computer systems with many cores and large main memory in the HPI Future SOC LabFuture SOC Lab (service-oriented-computing)
