In response to the information needs of scientists and physicians who work in the field of vision, we have developed a direct-access, on-line specialized information retrieval system which combines computer-assisted instruction and bibliographic retrieval. An essential feature of the system is its accessibility via remote computer terminal. The key to the data base is a thesaurus which contains specific terminology arranged in a hierarchical structure. The thesaurus is used both for indexing the literature and for retrieving the information stored in the computer. Courses of instruction on selected subjects in ophthalmology have been programmed and form part of the data base. A search of the literature retrieval system by single subject, or by a combination of several subjects chosen from the thesaurus, retrieves the appropriate bibliographic citations. The response to the service offered by the Vision Information Center indicates that the center should expand its facilities to satisfy the needs of its clients.
为满足视觉领域科研人员和医生的信息需求，我们开发了一个直接访问的在线专业信息检索系统，该系统结合了计算机辅助教学和文献检索功能。该系统的一个基本特点是可通过远程计算机终端访问。数据库的关键是一个叙词表，它包含按层次结构排列的特定术语。叙词表既用于文献索引，也用于检索存储在计算机中的信息。眼科选定主题的教学课程已被编程并成为数据库的一部分。通过单一主题或从叙词表中选择的几个主题的组合来搜索文献检索系统，可以检索到适当的文献引用。对视觉信息中心提供的服务的反馈表明，该中心应扩大其设施以满足客户的需求。
