Network science aims at developing methods and tools for the collection, processing, and analysis of relational data (e.g., from social media or sensor data) which can be modeled as a network. Network models facilitate the explanation and prediction of the structure and dynamics of social systems.
Our research on Network Science
- Measuring face-to-face interactions via RFID sensors in various environments (e.g., academic conferences) and combining these data with survey data on behavior and personality traits
- Networks of interactions between users of online platforms (such as Wikipedia, Reddit, Twitter), statistical modeling of patterns of online interactions (regarding information behavior, cooperation, conflict etc.)
- Generative network models which aim to explain and predict the behavior of subpopulations (e.g., collaborations between female and male researchers)
- Cultural networks that link geographical regions through shared online preferences
