项目摘要

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 InternetThis 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 WWWSince 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.

随着互联网的使用广泛，应用区域越来越大。但是，虽然互联网是一个拥抱的数据包，并且类似于数据库，但数据格式过于多样化，无法使用数据库。因此，很难有效利用它们。这项研究实现了以下三项贡献：（1）本地互联网的分析和应用本研究提议在Internet上检索本地信息的方法，并与ISP（京都）合作（Kyoto-Inet）在京都周围有许多用户。特别是，它主要由两个建议组成。该信息与局部区域的密切相关性的计算方法以及网页的缓存技术经常访问。在后者中，我们证明，通过将方法应用于ISP的真实数据。（2）与wwwsince www的高级教育有助于实现遥远的学习系统，我们练习和评估了我们的长期研究建议合作，很有帮助。在京都教育委员会的情况下，这些系统应用于Horikawa高中的数学课程。我们已经从事教育活动，以鼓励在高仓和巨毛米纳米小学上提高学生的创造力。我们对构建学生理解过程的数据库进行了研究。这些系统与另一个系统不同，但现在仍在实践中。由于教师和学生的支持，这些系统正在广泛扩展。（3）电子商务数据库技术（E-Commerc）这项研究对方法进行了统计评估，以找出客户希望使用电子商务系统的商品。它对公司兼容的XML文档进行了理论研究。在电子商务中，保护版权比实际的商业活动更容易复制更为重要。它与林地，阿斯特和京都比较法律中心合作，为EC技术开发和版权保护做出了贡献。
