An automatic update system based on semantic web techniques to implement the drug-law checking automatically is proposed in this thesis. The design concept is to use OWL as the knowledge model. To represent the drug law knowledge, we view a drug law as a class of medical status, and we can use classification to implement the decision of drug use legality. This approach simplifies the design of inference engine. The OWL supports the syntax of class inherences, so it can reach the cognitive economy and shorten the drug laws encoding length. The OWL syntax can represent most drug laws style, so the system can just use one document and one inference engine to handle all drug laws rules.

本文导入语意网技术提出一法规检核同步化系统，来实现药品检核规则自动更新的功能，其主要设计理念为以语意网的OWL模型来实作法规检核系统，在法规的知识表徵上，系统将所有的药品规则视为医疗状态的类别，因此判别用药的合法性，便可使用分类运算达成，这简化了推理机的设计；利用OWL支援类别继承的语意，故能形成认知经济性效应，缩小医疗法规机器编码长度；最后OWL的语法能表示大部份规则型态，使得系统可以使用一个文件档，一种推理机模型便能表示所有的法规。
