This document discusses the challenges of governance in a complex world and proposes research directions for ICT-enabled governance. It notes that society is increasingly fast-changing while governance remains siloed and linear. This creates a gap between society and governance. It proposes that by 2020, policy-making could involve more collaborative and data-driven approaches utilizing modeling, simulation, and collective intelligence tools. Key research challenges include developing integrated and reusable models simulating large societal phenomena, facilitating collaborative modeling between citizens and groups, and ensuring real-time open government data. The document outlines several European research projects exploring these directions to support more evidence-based and participatory decision-making.
