Social Media Systems

Social computing systems are an emerging class of societal-scale human-computer systems facilitating communication between individuals, organizations, and governments. Through user studies, analysis of large datasets, and design and deployment of new systems, this field seeks to understand and influence the behavior of these systems and their users.

Groups and Researchers in this Field


Machine Learning and Large-scale Data Mining Methods

Manuel Gomez Rodriguez is a research group leader at the Max Planck Institute for Software Systems. He is interested in developing machine learning and large-scale data mining methods for analysis and modeling of large real-world networks and processes that take place over them. His research comprises several dimensions: developing models of these networks and processes, assessing their theoretical properties and limitations; developing machine learning algorithms to fit the models and computational methods to influence processes over networks; and validating models and methods on gigabite- and terabyte-scale real-world datasets. Ultimately, he aims to provide computational tools with applications in a variety of domains, e.g. social and information sciences, economics, decision theory, causality, and epidemiology. Read more

Social Computing

Krishna Gummadi heads the Social Computing research group at the Max Planck Institute for Software Systems. He is broadly interested in understanding and building networked and distributed computer systems. Currently, the group’s research focuses on social computing systems: an emerging class of societal-scale human-computer systems that facilitate interactions and knowledge exchange between individuals, organizations, and governments in our society. A few examples include social networking sites like Facebook, blogging and microblogging sites like LiveJournal and Twitter, and content sharing sites like YouTube, among many others. Through user studies, examining data, and building systems, the group aims to understand, predict, and control the behavior of their constituent human users and computer systems. Read more

Exploratory Data Analysis

Jilles Vreeken is a senior researcher in the Databases and Information Systems Department at the Max Planck Institute for Informatics, and leads the Exploratory Data Analysis independent research group at the Cluster of Excellence on Multimodal Computing and Interaction. His research focuses on exploratory data mining: developing theory and algorithms to identify interesting structures within given data. Of particular value here are statistical methods, such as information-theoretic principles of minimum description length and maximum entropy. Next, he develops efficient algorithms to extract these structures from large and complex data, and investigates how they can be used in a range of applications, including identifying rare diseases, e-health, bio-informatics, market analysis, product recommendation, etc. Read more

Knowledge Harvesting

Gerhard Weikum is a Research Director at the Max Planck Institute for Informatics, where he leads the Databases and Information Systems Department. He is also an adjunct professor in the Department of Computer Science of Saarland University, and a Principal Investigator of the Cluster of Excellence on Multimodal Computing and Interaction. The long-term objective of his research is to develop methodology for knowledge discovery: collecting, organizing, searching, exploring, and ranking facts from a wide array of structured, semistructured, and textual information sources, which may exhibit varying levels of credibility. His group’s approach towards this goal combines concepts, models, and algorithms from several fields, including database systems, information retrieval, statistical learning, and data mining.
