植物病理学文献计算机检索系统研究

A Flexible Information Retrieval System on Phytopathology

可在微机上运行的植物病理学文献检索系统,已在Foxbase或dBAsE III支持下开发成功,用户可以从作物、病原、研究专题、题录、作者、年份、期刊等几个方面查询到所需要的文献,查询结果以整齐的格式打印出,也可以各个条录单独地打印在卡片上;同时可以把挑选出的题录保留下来,成为某专题的数据库.检索词建立、查询操作等均在菜单提示下进行,键入代码或检索词即可查询,系统具有一定的模糊查询功能.本文提出的孪生数据库技术可节省大量的存储空间.

The information retrieval system on Phytopathology running on the Microcomputer supported by Foxbase or dBASE was established. Request topics would quickly be output when the search terms were input into the computer. According to the prompts in the menu, one can either type the codes standing for various crops, pathogens and subjects, or input the searching terms in Chinese. This system possesses the capacity of free text searching, so that the informal keywords in Chinese can be used as searching terms. Search results can be printted out either in neat format or in card format separately. Meantime the request topics can be retrieved as a special base. A twin base technique presented in the paper was drawn out to economize the memory space.
