Research Abstract

As the use of the Internet is widespread the application area is getting wider. However, while the Internet is a hug bundle of data and is analogous to databases, the data format is too diversified for the database-like use. Hence, it is difficult to utilize them efficiently. This research has achieved the following three contributions :
(1) Analysis and application of local Internet
This research proposed retrieve methods of local information on the Internet, cooperating with ISP (Kyoto-Inet) that has many users around Kyoto. Especially, it consists mainly of two proposals ; computation methods of how strongly the information is associated with the local area, and caching technologies of web pages accessed frequently. In the latter we showed that it is practically useful, by applying the method to the real data of the ISP.
(2) Advanced Education with WWW
Since WWW is helpful to realize distant learning systems, we practiced and evaluated our long-time research proposals Cooperating with Kyoto board of education, the systems were applied to math classes at Horikawa high school. We have practiced educational activities to encourage to improve students' creativity at Takakura and Gosho-minami grade schools. We did researches on constructing databases of students' understanding processes. These systems are distinct from on another, but are still in practice now. Because of support by the teachers and students, the systems are getting widespread.
(3) Database Technologies for Electronic Commerce (E-Commerc)
This research presented statistical evaluations of methods to find out the items customers hope to get on e-commerce systems. It did theoretical researches on XML documents compatible among corporations. In E-Commerce, it is more importan to protect copyrights because of easier duplication of the items than in real commercial activities. It cooperated with Woodland, ASTEM and Kyoto Comparative Law Center to contribute to EC technology development and copyright protection.
