Multimedia plays a major role in medicine. Databases containing images, movies or other types of multimedia objects are increasing in number, especially on the WWW. However, no good retrieval mechanism or search engine currently exists to efficiently track down such multimedia sources in the vast of information provided by the WWW. Secondly, the tools for searching databases are usually not adapted to the properties of images. HTML pages do not allow complex searches. Therefore establishing a more comfortable retrieval involves the use of a higher programming level like JAVA. With this platform independent language it is possible to create extensions to commonly used web browsers. These applets offer a graphical user interface for high level navigation. We implemented a database using JAVA objects as the primary storage container which are then stored by a JAVA controlled ORACLE8 database. Navigation depends on a structured vocabulary enhanced by a semantic network. With this approach multimedia objects can be encapsulated within a logical module for quick data retrieval.
多媒体在医学领域发挥着重要作用。包含图像、电影或其他类型多媒体对象的数据库数量不断增加,尤其是在万维网上。然而,目前还没有良好的检索机制或搜索引擎能够在万维网提供的海量信息中有效地找到此类多媒体资源。其次,搜索数据库的工具通常不适合图像的特性。HTML页面不允许进行复杂搜索。因此,要建立更便捷的检索方式,需要使用像JAVA这样更高层次的编程语言。使用这种与平台无关的语言,可以为常用的网络浏览器创建扩展程序。这些小程序提供了用于高级导航的图形用户界面。我们使用JAVA对象作为主要存储容器实现了一个数据库,然后由一个JAVA控制的ORACLE8数据库进行存储。导航依赖于由语义网络增强的结构化词汇表。通过这种方法,多媒体对象可以封装在一个逻辑模块中,以便快速检索数据。
