Die Erzeugung, Verknupfung und Auswertung von grossen Datenmengen (oft als "Big Data" bezeichnet) gewinnt in nahezu allen Lebensbereichen rasant an Bedeutung. Mit dieser Entwicklung sind Fragen von erheblicher gesellschaftlicher Relevanz verbunden. Die Diskussionen uber eine neue Balance zwischen der Ausschoepfung von Innovationspotentialen einerseits und der Realisierung individueller und gesellschaftlicher Werte andererseits haben erst begonnen. Der Band nahert sich denen mit Big Data verbundenen gesellschaftlichen Herausforderungen aus einer multidisziplinaren Perspektive.
