Abstract

We developed an online keyword search system on a WWW server to help medical doctors to introduce their patients to specialists. The system stores special knowledge and advanced techniques of 287 medical specialists in Kyushu University Hospital. The data set was presented by the medical specialists themselves. Specialists can rewrite their data set using the browser anytime to keep their data set up to date. In addition, the specialists are reminded to keep their data set up to date by direct mail once a year. The system does not use any database management systems. We used only two text files and the "grep" command, one of the basic commands of the UNIX system. Then, it takes less than 1 sec to search one medical specialist's data set from 200 specialists' data sets. The system is useful not only inside the hospital but also for practitioners in the local area.
