Today's web is so huge and diverse that it arguably reflects the real world. For this reason, searching the web is a promising approach to find things in the real world. This paper presents NEXAS, an extension to web search engines that attempts to find real-world entities relevant to a topic. Its basic idea is to extract proper names from the web pages retrieved for the topic. A main advantage of this approach is that users can query any topic and learn about relevant real-world entities without dedicated databases for the topic. In particular, we focus on an application for nding authoritative people from the web. This application is practically important because once personal names are obtained, they can lead users from the web to managed information stored in digital libraries. To explore effective ways of finding people, we first examine the distribution of Japanese personal names by analyzing about 50 million Japanese web pages. We observe that personal names appear frequently on the web, but the distribution is highly in uenced by automatically generated texts. To remedy the bias and find widely acknowledged people accurately, we utilize the number of web servers containing a name instead of the number of web pages. We show its effectiveness by an experiment covering a wide range of topics. Finally, we demonstrate several examples and suggest possible applications.
