文献[1]的第四部分曾“从查全率、查准率的定义出发,用数学的方法给查全率与查准率的互相制约关系以较为严格的说明”。笔者认为,“说明”是不严格的,结论是不成立的,该文所采用的数学方法也是值得商榷的。最近笔者还从文献[2]的有关部分发现,把 The fourth part of the literature [1], “starting from the definition of recall rate and accuracy rate, uses the mathematical method to give a more rigorous explanation to the mutual restraint relationship between recall rate and accuracy rate.” The author believes that the “explanation” is not strict, the conclusion is not valid, the mathematical method used in the article is also debatable. Recently I also found from the relevant part of the literature [2], put
