项目摘要

This research has been studied on technical problems in order to utilize multimedia data distributed over networks. Since amount of database on internet increases drastically, it is difficult to find out required data from such environment. Hihg-level search facility is, therefore, required to solve the problems. This research focuses on geographic data, since a geographic system is a typical application of multimedia databases. Data over the distributed network often contain a kind of geographic information, so that maps can be considered as important interfaces for multimedia users.In this research, the following three topics have been studied, and a practical system has been developed in order to realize effective search mechanisms for data on internet.1.Function to decompose multimedia and hypermedia data.2.Function to compose usr-required representation from data of various source.3.Functions to display data which cannot be composed by 2 and to support modification of users query.For decomposition/composition of media objects, it is required to understand the characteristics of objects. Composite objects are media objects which exist on temporal or spatial environment. If a composite object is decomposed, resulting objects can be also become media objects. This research also proposed thesauruses operations, interference of queries, reutilization of query generation processes, and co-existence relationships as new thesauruses. In order to reduce the time to generate maps, temporal composition and concurrent composition mechanisms have been developed.

已经研究了有关技术问题的研究，以利用在网络上分布的多媒体数据。由于互联网上的数据库数量大大增加，因此很难从这种环境中找到所需的数据。因此，HIHG级搜索设施是解决问题所需的。该研究重点是地理数据，因为地理系统是多媒体数据库的典型应用。分布式网络上的数据通常包含一种地理信息，因此地图可以被视为多媒体用户的重要接口。在这项研究中，已经研究了以下三个主题，并且已经开发了实用的系统，以实现有效的有效性搜索机制在Internet上的数据。1。分解多媒体和HyperMedia数据的功能。查询。对于介质对象的分解/组成，需要了解对象的特征。复合对象是在时间或空间环境上存在的介质对象。如果分解复合对象，则可以将结果对象成为媒体对象。这项研究还提出了词库操作，查询的干扰，查询生成过程的重新化以及作为新的词库的共存关系。为了减少生成地图的时间，已经开发了时间组成和并发组成机制。
