Abstract
The utilization of healthcare data analytics is expected to play an important role for future health management and public health policy making, especially considering the problem of our aging society. In this short paper we present the conceptual design of a Web based environment called Policy Development Toolkit (PDT), which aims to promote the exploitation of heterogeneous holistic health data and pre-existing knowledge on public health policy models. The proposed approach incorporates mechanisms for forecasting, causal and risk analysis, as well for the compilation and visualization of predictions.
