福岛^+──一种改进的福岛方法

FUKUSHIMA^+——AN IMPROVED FUKUSHIMA METHOD

本文分析了福岛法的缺陷及其起因,提出了称为福岛+的新的运算法。并编成程序在AST 386微机上得到了实现。用本法AST 386微机上处理了300多个国际联机检索提问逻辑式,结果表明:用本法处理所需工作区最大占用数为5,而用福岛法有63%的提问式需占用5-7个工作区,并有17%的工作区溢出率。

Based on the analysis of the short comings of Fukushima method and its origin,a new method called Fukushima+ i s presented in this paper.More than 300 retrieval prescriptions used in the int ernational online retrieval have been processed by both Fukushima method and F ukushima+ on AST 386 microcomputer.The results indicate that the maximum number of working areas needed for all the qu ery formulations in Fukushima+ is only 5,but in original Fukushima method,5-7 working areas are required for only 63% of query formulations with 17% of over flow rate.
