档案计算机检索是指利用计算机对档案信息进行查找与利用与传统的档案信息查找方法相比,计算机检索的本质没有变,只是检索的手段、信息的表示方式、存贮结构和匹配方法发生了变化。计算机检索是用计算机可以识代码来表示信息,用便于计算机决速存取的方式来存贮信息,其匹配方法由人工比较变为机械匹配,匹配标准由隐式变为显式。在计算机匹配过程中,原先表达概念的问语符号变为没有内涵的字符串;信息检索过程是字符串匹配和逻辑运算的过 File computer retrieval refers to the use of computer file information to find and use Compared with the traditional file information search method, the nature of computer retrieval has not changed, but the means of retrieval, information representation, storage structure and matching methods have changed . Computer retrieval is the use of computer-readable code to represent the information, with a computer-speed access to store information, the matching method from manual comparison into a mechanical match, the matching standard from an implicit to explicit. In the process of computer matching, the question symbol originally expressing the concept becomes a string without meaning; the information retrieval process is a string matching and logic operation
