Internet Distributed Database

在本研究中，我们开发了一个互联网网页搜索机器人，以及一个名为“千里感”的搜索引擎。“森日根现在已经投入使用，每天大约有10万人进入。根据千里观收集的数据，可以推断出日本目前大约有10万个网页，每半年翻一番。目前日本最受欢迎的网页是《朝日新闻》网页。搜索机器人需要大约一周的时间来搜索日本所有网页，这太长了，无法更新。因此，分布式机器人的设计和实施。还提出了用于该服务的协议。

In this research, we developed an Internet Web home page search robot, and a search engine called "Senri-gan."Senri-gan is now in service, and about 10thosands access are being made everyday. Using data collected by Senri-gan, we can infer that there are about 100thousands Web pages now in Japan, and the number doubles in every half an year.Right now, the mosy popular page in Japan in terms of the number of links pointing it is "Assahi Shinbun" page.The search robot takes about a week to search all pages in Japan, which is too long to up-date. Hence distributed robots have been designed and implemented. Protocols for this service has been also proposed.
