—With the popularization of computers and
advancement of information technology (IT), there has been a
rapid growth in the application of IT, thus greatly changed
living habits, consumption behaviors, and health awareness of
the modern society. Meanwhile, the demand is ever increasing
for healthcare services based on information and knowledge
that lead to personal health attention by people gradually.
This research aims to design and develop an ontology driven
knowledge-base system for generating personalized Diet-Aid
web services based on standard Health Level Seven (HL7)
health screening data. The system provides intelligent,
personalized web services of Diet plan for users through an
ontological knowledge engine. The system developed is capable
of generating a dietetic plan and filter out unsuitable food on
site according to user’s health conditions and the accessible
recipe information. The REST-based Diet-Aid web services can
be accessed service ubiquitously by using any Internet-enabled
—Diet plan, health level seven international
