模态逻辑中的过滤方法被认为发展了一种形成粒推理的方法，粗略地说，粒推理指的是基于粒度的人类推理。然而，这种方法起源于纯粹的逻辑问题，比如可判断性。在此基础上，利用粗糙集理论中的上、下近似，引入了相对过滤的扩展概念。最后给出了一个使用相对过滤进行推理的实例。
The filtration method in modal logic is considered to develop a way of formulating an aspect of granular reasoning, which, roughly speaking, means human reasoning based on granularity. The method, however, originates in purely logical problems like decidability. Then, for our purpose, an extended concept of relative filtration is newly introduced using lower and upper approximations in rough set theory. An example of reasoning process using the relative filtration is illustrated.
