Smart city capabilities are currently realized in a staggered fashion or they exist in silos. However continuous improvement and personalization is expected by citizen for sustained engagements. This is possible only if the service enabling platform is able to continuously learn about the citizen persona and her need. This enables a platform to transform the way the services are delivered to an individual citizen. The current study provides insights to develop Digital Citizen Engagement Framework (DCEF) to build a platform for citizen to personalize the engagements with smart city services. The framework is arrived at through Content Analysis, a qualitative research methodology identifying various categories and themes to manage technical components and features that need to be part of DCEF that can be deployed in a Smart City to make it future ready. Our initial experiments on an Ambient Assisted Living (AAL) use-case for geriatric care proves the effectiveness of our proposed framework.
