| Research Abstract |
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.
