Norihiro Ohira, Shinichi Tomiyama

  For solving problems inside an enterprise or research groups, finding the expert persons who have the pertinent knowledge is a key for solving the problems. In recent years, several expert search systems have been devised for finding experts. However, it has been pointed out that the conventional methods used in such systems may not be capable of properly finding experts in case where the search keywords have some synonyms or an expert has multiple areas of specialization. In this study, applying a hierarchical tagging technique, an expert finding system has been developed which can output more appropriate rankings in such cases.
