To help users select and understand people during searches for them, we present a method of assigning Nippon Decimal Classification (NDC), which is a system of library classification numbers, to people on the web. By assigning NDC numbers to people, we can assign not only labels to people but also build a NDC-based people-search directory. We use a relative index in NDC, which lists the related index terms attached to NDC. We developed a prototype based on this approach. We evaluated the usefulness of our proposed method and directory and found that extracting relative index terms from the titles of web pages outperformed comparative methods.
