社会的发展进步离不开信息的存贮和检索。传统的人工查询资料方式,远远不能适应社会信息发展的步伐,取而代之的便是计算机辅助人们进行各种信息的管理和查询。计算机在检索领域里的应用为人们快速准确全面地获取有关信息,提供了一条崭新的途径。近年来发展起来的“电子档案系统”便是这一技术在档案界实际应用的成功范例。 在电子档案系统中,计算机存贮空间的大小是一个很重要的参数,在信息量增大到一定程度以后,检索软件编制的好坏,便直接影响到查找效果。 例如:要查找“单分子反应动力学”的有关资料,若查“动力学”,可能会命中成千上万篇;若查“单分子、反应动力学”,或者将查找词录入有误,可能一篇也找不到。这也是计算机查找的被动性。可见,如何与计算机对话,是衡量一个检索软件水平的标志。目前,微型机的普及应用,使各行各业都有一批软件研制人员研制各种检索软件,但一般用单项查找较多,不考虑上位类的自动登录和下位类的细分功 The development of society is inseparable from the storage and retrieval of information. The traditional method of manual inquiry of data, far from being able to adapt to the pace of social information development, replaced by computer-assisted people to manage and query a variety of information. The application of computer in the field of retrieval provides a new way for people to obtain relevant information quickly and accurately. The “electronic file system” developed in recent years is a successful example of the practical application of this technology in the field of archives. In the electronic file system, the size of the computer storage space is a very important parameter, the amount of information increased to a certain extent, the quality of the search software, it will directly affect the search results. For example, to find information about “single molecule reaction kinetics”, if you look at “Kinetics,” you may hit tens of thousands of articles. If you search for “single molecule, reaction kinetics,” or enter a search term incorrectly, May not find one. This is also the computer search of the passive. Obviously, how to talk to a computer is a measure of the level of a search software. At present, the popularization and application of microcomputers, so that all walks of life have a group of software developers to develop a variety of search software, but usually single find more, regardless of the upper class automatic login and sub-class breakdown
