A Study on Efficient Information Sources Monitoring Method in Large-scale Network

在这项研究中，我们研究了一种有效的方法，从分散在一个大规模的网络，如互联网上的信息源的信息检索。该方法针对不同信息源的信息更新时间周期，制定有效的信息源监控计划，使获取的信息保持最新状态。此外，我们证实了该方法的有效性，通过使用计算机模拟和原型系统的实现。

In this study, we investigated an efficient method of information retrieval from the information sources scattered on a large-scale network like the Internet. Focusing on the information update time-cycle which varies with each information source, the method enables to make an effective schedule of information sources' monitoring so as to keep the retrieved information freshly updated. Furthermore, we confirmed the effectiveness of the method by using computer simulations and prototype system implementations.
