China's National Health Policies: An Ontological Analysis.

The health care system in China is facing a multitude of challenges owing to the changing demographics of the country, the evolving economics of health care, and the emerging epidemiology of health as well as diseases. China's many national health care policies are documented in Chinese text documents. It is necessary to map the policies synoptically, systemically, and systematically to discover their emphases and biases, assess them, and modify them in the future. Using a logically constructed ontology of health care policies based on the common bodies of knowledge as a lens, we map the current policies to reveal their 'bright', 'light', and 'blind/blank' spots. The ontological map will help (a) develop a roadmap for future health care policies in China, and (b) compare and contrast China's health care policies with other countries'.
