The aim of this research involves a development and evaluation of information system using the Internet to support satellite education. The followings are the achievements of this research.(1)Development of a System to Deliver Slide Patterns of Lecturer and a Feedback System Using the InternetThis system can deliver slide patterns shown by lecturer to a learners' web browser via a network or the Internet. A slide pattern is sent in sync with a lecture. By this function, learners can read slide patterns more clearly than a TV screen sent by satellite. In addition to this, this system can gather learners' real-time response for an enquete via the Internet. Furthermore, a lecturer is able to show a graph of result on a web browser.(2)Development of Notification System for Educational InformationUsers of this system can receive e-mail for notification of new educational information, which has relations with keywords that users have registered. This system has been released and used since September 2002 in the National Information Center for Educational Resources (NICER). Furthermore, this system have a function to detect whether an web page update is worth for users.(3)Development of an Information Retrieval System for Video-Based Learning MaterialsIn this system, video material is time coded by matching with manually transcribed speech data. Using time coded speech data, an information retrieval system of video-based learning materials was developed. This system offers a full-text retrieval, and replays retrieved video clips in which query terms are contained.

本研究的目的涉及利用互联网支持卫星教育的信息系统的开发和评估。本研究的成果如下：(1)开发利用互联网传送讲师幻灯片模式的系统和反馈系统该系统可以通过网络或互联网将讲师演示的幻灯片模式传送到学习者的网络浏览器。幻灯片模式与讲座同步发送。通过此功能，学习者可以比卫星发送的电视屏幕更清晰地阅读幻灯片图案。除此之外，该系统还可以通过互联网收集学习者对队列的实时响应。此外，讲师还可以在网络浏览器上显示结果图表。 (2)开发教育信息通知系统 该系统的用户可以收到与用户注册的关键字相关的新教育信息通知的电子邮件。该系统自2002年9月起在国家教育资源信息中心（NICER）发布并使用。此外，该系统还具有检测网页更新是否值得用户使用的功能。(3)基于视频学习材料的信息检索系统的开发在该系统中，视频材料通过与手动转录的语音数据匹配来进行时间编码。使用时间编码的语音数据，开发了基于视频的学习材料的信息检索系统。该系统提供全文检索，并重播检索到的包含查询词的视频剪辑。
