A STUDY OF KNOWLEDGE BASE ORIENTED IR SYSTEM FOR AUDIO VISUAL MEDIA

综合科学教育必须同时涵盖自然科学、社会科学、人类学等广泛领域。为此，经常使用团队教学，并使用一些多媒体教材。主要实现了以下目标：(1)收集了中小学、高校、成人教育、企业职工技术培训和非技术培训使用的视听教材信息，如16mm短片、录像带等，建立了1.4万册教材数据库。(2)将(1)中准备的数据库转移到大阪大学大型计算机中心。在那里，通过名为“JSR”的校际网络，开始了一项全国性的信息检索服务。(3)利用(1)的数据库，编制了一份1000页的教材目录，分发给大量感兴趣的组织。(4)面向知识库的视听媒体IR系统开发。

Comprehensive science education must cover such broad fields as natural science, social sience and anthropology simultaneously. For this purpose team teaching is often used, together with a number of multimedia teaching materials.The following goals were accomplished:(1) Information on audio-visual teaching materials to be used in schools, universityies, adult education programs, and both technical and nontechnical training programs for company employees such as 16mm short films and video tapes was collected, and a data base for 14,000 teaching materials was prepared.(2) The data base prepared in (1) was transferred to the Large Scale Computer Center of Osaka University. There, through the interuniversity network under the title of "JSR" , a nationwide information retrieval service was started.(3) Using the data base in (1) , an 1000-page catalog of teaching materials was prepared and distributed to a large number of interested organizations.(4) Development of a Knowledge base oriented IR system for audio-visual media.
