Abstract
Recently, public interest in health is growing, and the number of people who have a regular medical checkup is increasing for early detection of disease. On the other hand, the rapid development of information technology gives us much medical information, and the demands on needs for medical support system will continue to grow. The aim of this study is to develop a hospital search support system (HSSS) for integrated medical support system. It employs Hierarchical Keyword Graph (HK Graph) for the disease search support system (DSSS). DSSS can infer the name of disease from the symptoms inputted by a user. First, this paper shows the extraction method of symptom words for DSSS. And then it shows disease ranking method based on the information of symptoms on HK Graph considering inputted severity of symptoms by user. This paper studies the effectiveness of the proposed method based on the accuracy and coverage rate of symptoms and the transition of ranking of diseases.
