论文部分内容阅读
1980年我在《情报科学》第2期上曾论述并绘出R—P的关系曲线图与其文氏图,并对图上的隅角A、B、C点作了简单的解释,说明了R—P的互逆关系。1982年在青岛召开的第2届全国机检年会上,我又发表论文,对美国国家橡树岭实验所O’Hara于1970年发表的对R-P矩阵图的边线与隅角的解释作过补充与修正,并率先提出模拟检索过程的动态文氏图的概念。这些问题曾引起国内学者的关注与讨论,有不同意见,是件好事。我仍认
In 1980, I discussed and plotted the R-P relationship graph and its Venn diagram in the second issue of “Information Science”, and gave a brief explanation of the points A, B and C in the figure. R-P reciprocal relationship. In 1982, at the 2nd National Inspection Conference held in Qingdao, I also published a paper supplementing the interpretation of the edges and corners of the RP matrix published by O’Hara at the Oak Ridge Institute in the United States in 1970 With amendments and pioneered the concept of a dynamic Ventringer that mimics the retrieval process. These issues have aroused the concern and discussion of domestic scholars, have different opinions, is a good thing. I still recognize
