Chiba University Hospital website has a lot of information and helps visitors to find all kinds of information about the hospital, while too much information makes it difficult to find a suitable doctor as a specialist for them. Visitors have to search every department website one by one. This task is very troublesome, especially large hospital. To solve this problem, we developed a specialist search engine. By entering a disease name, the engine will find the specialists for the disease. The engine can control synonyms by using International Statistical Classification of Diseases and Related Health Problems (ICD), Japanese Standard Disease-Code Master and arrange the specialists in order of the experience.
