Abstract
An application service provider system for healthcare with a data mining function has been developed. The system provides computer-based healthcare service over the Internet to advice customers on how to improve their lifestyles on the basis of association rules relevant to their health and lifestyle data. These association rules can be automatically extracted using a data mining technology on the server computer on the basis of customers' stored time-series health and lifestyle data that are transferred through their mobile phones or PCs. The healthcare adviser can send comments made up of the rules to the customers over the Internet.
