摘要
作者在《从检索实例看查全率与查准率之间的关系》一文中揭示了查全率与查准率之间不仅存在互逆关系 ,而且还可以存在互顺关系和其他关系。本文则对这些关系进行理论上的分析论证 ,以证实这些关系的普遍性与客观性。
The document “Relationship between Recall and Precision Ratio in Terms of Retrieval Example” reveals that there is not only the inverse relationship,but also the direct and other relationship between them.This paper carries out the theoretical analysis and proof of these relationships so as to verify its universality and objectivity.
