目前,在计算机检索系统未进入应用阶段的各地、市局科技情报站中,多数的单位著录标引跟不上,数据量不足,存在情报站购置一台台计算机如同一口口等米的锅,在等待着数据的输入,数据充足,计算机可投入运行;数据不足,它就只能长期赋闲,或充当摆设,因此紧紧抓好数据准备工作是实现情报计算机检索的当务之急!所谓数据准备,即根据国家有关标准,将一次文献(情报)通过著录、标引转换或二次文南,并输入计算机,转换为机读形式.数据准备工作专业性强、花费人力多,工作量大,数据准备工作的好坏是检索系统建设成败的关键.
At present, most of the units in the Municipal Science and Technology Information Station have failed to keep up with the index numbers of the scientific research units in the computer science and technology information centers, and the data amount is not enough. There is an intelligence station to purchase a computer such as a rice pan, Waiting for the data input, enough data, the computer can be put into operation; data is not enough, it can only be idle for a long time, or act as a decoration, so firmly grasp the data preparation is to achieve intelligence computer retrieval urgent task! The so-called data preparation, namely According to the relevant national standards, a document (intelligence) through the record, index conversion or secondary Wennan, and enter the computer, converted to machine-readable form.Data preparation work professional, labor-intensive, heavy workload, data preparation The quality of the job is the key to the success of the search system.
