This book provides a profound discussion about the Blogosphere, the world of interlinked weblogs in the World Wide Web. The authors guide the process of understanding and analyzing the Blogosphere as an example for social networks and discuss the weblog phenomena with the ultimate objective to conceptualize a framework capable of analyzing and providing the rehashed information of the Blogosphere. The main goal is to show new ways and measures to extract reliable and valuable knowledge out of the Blogosphere. Starting with the first Web server and just a few web pages in 1990, the World Wide Web has since then experienced tremendous acceptance and growth. Nowadays, it is a platform used daily by millions of people worldwide to publish and share information online and to reference related resources on the Web through so-called hyperlinks. By creating a vast, global and easy to use network of information it has revolutionized the way people disseminate and exchange information.

Christoph Meinel (1954) is President and CEO of the Hasso-Plattner-Institut for IT-Systems Engineering (HPI) and full professor (C4) for computer science at the University of Potsdam. His research field is Internet and Web Technologies and Systems. Beside he is a teacher at the HPI School of Design Thinking, a visiting professor at the Computer Science School of the Technical University of Beijing (China) and a research fellow of the interdisciplinary center SnT at the University of Luxembourg. Since 2008 he is program director of the HPIStanford Design Thinking Research Program. He is author or co-author of 10 text books and monographs and has published more than 350 per-reviewed scientific papers in highly recognised international scientific journals and conferences. Philipp Berger is a Ph.D. student at the Hasso-Plattner-Institute,Germany, investigating new algorithms for analyzing social media channels. Currently, his focus is the identification of important authors and topics among weblogs.His research results are part of a joint research project called BlogIntelligence that offers a web prototype portal (blog-intelligence.com). Philipp, born in Berlin, earned his Bachelor and Master degree in IT Systems Engineering at the Hasso-Plattner-Institute. During his studies he went abroad for an internship on product feature extraction of product Reviews at SAP Labs, India. Dr. Justus Bross joined the research organization "Bell Labs" of Alcatel-Lucent as head of the newly formed research department "Strategic Industries Research". He published several papers in the research area of the collaborative- and social web in general, and weblogs in particular. His thesis also focuses on the Understanding and Leveraging the Social Physics of the Blogosphere and was mentored by Prof. Dr. Christoph Meinel. Justus, born in 1979 in the city of Bonn (Germany), graduated from the University of Maastricht in theNetherlands with a master degree (M.Sc.) in International Business, earned a master degree in engineering (MBE) from the Steinbeis academy and the D.E.L.E language diplomaat the University of Salamanca in Spain. He wrote his final thesis about the disruptive character of VoIP in collaboration with Deutsche Telekom AG. Patrick Hennig, born in 1988 in the city of Walldürn, Germany, got a bachelors degree (B.Sc) in IT-Systems Engineering from Hasso-Plattner-Institute in Potsdam, Germany. He wrote his bachelor thesis in cooperation with SES Astra, Belgium and SAP Research Pretoria, South Africa about project management with SCRUM in small scale projects. After he received his bachelors degree he studied abroad at University of Coimbra, Portugal in Computer Engineering. Since his masters studies (M.Sc.) in IT-Systems Engineering and the master thesis about "Identifying Trends based on the Blogosphere" at Hasso-Plattner-Institute in Potsdam, Germany, he is focusing on the topic of social media monitoring especially by working on an analysis framework for blogs, integrated into a web portal (blog-intelligence.com), with the objective to leverage content- and context-related structures and dynamics in the blogosphere. Particularly he is working on the challenge to do real-time analyses on this big set of data. Currently, Patrick is a PhD student at Hasso-Plattner-Institut in Potsdam, Germany.
