Philipp Berger

Social Network Researcher, Software Engineer, Phd Student, Data Scientist

My name is Philipp Berger and I study and work as Phd student and research associate at the Hasso Plattner Institute, Germany.
My main research focus is social network analysis. Thereby, I am working on a full-blown prototype reaching from an extraction component to diverse analytical algorithms and easy-to-use visualizations. The problems of Social Media Analytics and Network Mining are so manyfold that I recommend everybody to join this field!


Information Visualization Weblogs Analyzers Data Framework Blogosphere Crawler Content Extraction Intuitive Bloggers Blogs

The BlogIntelligence portal is the last step in a long history of research and scientific work on the upcoming topic and media phenomena of weblogs. For years, there have been high-effort research activities on how to index and examine the blogosphere. This project shows, by way of example, in which perspectives the entirety of weblogs can be analyzed and visualized in order to extract valuable aggregated information.
