網路上資訊的快速成長成為民眾獲取醫療資訊的來源之一，然而醫療資訊有其專業性，而網路資訊的氾濫無法有效避免民眾接收錯誤的醫療資訊，加上眾多的資訊湧入易造成資訊過載，因此如何快速的找到正確的醫療資訊尤為重要。本研究建置一套醫療知識查詢系統，透過Web Spider 技術搜索以瑞士健康網站基金會（Health On the Net Foundation、HON）評鑑網站八大原則為基礎，經過衛生署五大標準認證之網頁頁面並進行發掘連結，從中擷取醫療訊息後以網頁排序技術給予民眾最新資訊。如此本系統除可針對醫療知識進行快速查詢外，並可提供最新的訊息給與使用者。

The rapid growth of information on the network becomes a source for the public to obtain medical information. However, medical information is professional, and the network cannot effectively prevent people from receiving the wrong information. Furthermore, much of the influx of information could easily lead to information overload. Therefore, quickly finding the appropriate medical information is particularly important. In this study, we built a medical knowledge query system to search and explore the link to the websites that are certified by the Department of Health through Web Spider technology. The method of authentication is based on the five criteria and the eight principles established by Health On the Net Foundation. After capturing the medical information from the website, we used web page ranking technology to give people the latest information. In addition to quickly query for health information, the system can provide the correct knowledge to users.
