关于“R-P矩阵的边线与隅角”问题

ON THE SIDELINE AND CORNER PROBLEM OF R-P MATRIX

文章在系统讨论R—P概念的基础上，着重论述了所谓“R—P矩阵的边线与隅角”问题。对于与此相关的“R—P互逆相关性”问题也发表了原则性的见解。作者认为：“R—P矩阵”问题是由于处理方法不当引起的，而“R—P互逆相关性”问题则是由于问题本身的复杂性造成的。因此，解决这两个问题的方法应有所不同。

This paper discusses emphatically the problem of ＂sideline and corner of the R-P matrix＂ on the basis of a systematic study of the inverse relationship between recall and precision on which a personal viewpoint of the author, in principle, is also presented, In his opinion, the first problem arises from the wrong methods used for its solution, while the second is the very complexity of the problem itself, Therefore, it is necessary to solve the two in different ways,
